I will be straight with you: for years I filed El Salvador under places I would get to eventually. Tiny country, a rough reputation in the old news, no direct flight from Singapore, nothing on my list. Then a friend who surfs sent me a photo of a black-sand beach at sunset with a line of pickup trucks parked in front of a seafood shack, and the caption was simply, 'Why did nobody tell us?' That photo started a long habit of reading, asking and planning, and this guide is what came out of it. It is written for Singapore travellers who are curious but cautious, which is exactly where I started.
El Salvador is roughly the size of Wales, small enough that you can wake up on a volcano rim, eat lunch in a flower-lined mountain village and watch the sun drop into the Pacific the same day. It is the smallest country on the Central American mainland and the only one without a Caribbean coast. It uses the US dollar, which makes budgeting painless. Its food is built around one gloriously simple thing, the pupusa. And in recent years its tourism has grown quickly, so much that surf towns that were sleepy a decade ago now have boutique hotels and yoga decks.
What follows is practical rather than poetic: who needs a visa, how the long journey from Singapore really works, when the weather helps you, what a day costs, how to stay safe without being paranoid, where to go, what to eat and how to stay connected. I have also added a sample week, a table of neighbouring trips, and a short section on the two bookable items we currently list for El Salvador. Where something changes quickly, such as entry rules or security conditions, I say so and point you to the official source rather than pretending a blog post can be the final word.
El Salvador at a glance
Before the detail, here is the one-screen summary I wish I had been given at the start. Treat it as a planning cheat sheet, and read the sections below for the reasoning behind each line.
| Topic | What to know |
|---|---|
| Capital and main airport | San Salvador; the international airport (Monseñor Óscar Arnulfo Romero, code SAL) sits on the coastal plain roughly 45 km from the capital |
| Currency | US dollar (coins are the same size and value as American ones; some local centavo coins circulate too) |
| Language | Spanish; English is common in surf towns, upmarket hotels and tour offices, rare elsewhere |
| Time difference | Singapore is 14 hours ahead of El Salvador (no daylight saving there) |
| Electricity | 120 V, flat two-pin sockets (type A and B); bring a Singapore-to-US adapter |
| Best months | November to April, the dry season |
| Singapore passport | Visa-free entry for short tourist stays under the regional four-country arrangement; confirm current rules before you fly |
| Typical trip length | 5 to 8 days is comfortable; the country is small and distances are short |
| Biggest surprise | How easy and cheap it is to eat well, and how quickly the landscape changes |
Do Singapore passport holders need a visa?
This is the question everyone asks first, so let me answer it carefully. Based on the embassy and government sources we track, holders of Singapore passports can currently enter El Salvador for tourism without a prior visa. The stay allowed falls under the Central America Four (CA-4) arrangement, which El Salvador shares with Guatemala, Honduras and Nicaragua, and that arrangement works on a combined 90-day allowance counted across all four countries, not 90 days in each. Entry is usually granted at immigration on arrival, and some travellers are asked to pay a modest tourist card fee, so keep a few small US dollar notes handy.
Please do not treat that as permanent. Entry rules are the sort of thing that changes without much notice, and the practical details, such as whether an online pre-registration form or a health declaration is requested, can differ from one year to the next. Before you buy tickets, check the current requirements for your own passport on our visa requirements pages, and cross-check with the Salvadoran consulate or the official immigration channel. If you are travelling on a different passport from a Singaporean one, say an Indian, Chinese or Philippine passport, a consular tourist visa may be required, and processing can take a few weeks, so start early.
A few document basics apply to everyone. Your passport should be valid for at least six months from the day you arrive and have blank pages. Airlines flying you onward from the Americas may ask for proof of an exit flight, because you are entering on a short-stay basis. If you are applying for a visa for El Salvador or for a transit country such as the United States, many embassies ask for a flight itinerary before they will stamp anything, and it makes little sense to buy a non-refundable ticket before you are approved. That is the situation our flight reservation service is designed for: a dated reservation for visa paperwork, which is not an issued ticket and does not promise that a visa will be granted. Read its description carefully so you know exactly what it is and is not.
Getting there from Singapore, honestly
There is no nonstop flight between Singapore and San Salvador, and I would rather say that early than let the fare search surprise you. The journey is a one-stop or two-stop affair, and the total travel time is usually somewhere between 28 and 40 hours door to door, depending on connections. The good news is that you have several sensible routing families, and you can pick the one that matches your tolerance for layovers and your appetite for a stopover city.
| Routing idea | How it works | Pros | Watch out for |
|---|---|---|---|
| Via the United States | Singapore to a US gateway, then a short regional hop to San Salvador | Many daily connections and the shortest overall time | US transit entry rules; long immigration queues on arrival |
| Via Europe or the Gulf, then the Americas | Long-haul to a hub, onward to a US, Mexican or Panamanian city, then to SAL | Chance for a free stopover; sometimes simpler transit rules | Three flights, more places for a delay to ripple |
| Via Panama City or Bogotá | Position yourself in Latin America, then take a regional carrier | Regional airlines with frequent flights to SAL | Two separate bookings can leave you unprotected if the first is late |
| Via Mexico City | Enter Mexico, then connect south | Good if you want to add Mexico to the same trip | Mexican entry formalities and baggage re-check on some tickets |
My own rule on long journeys is to book everything on a single ticket whenever possible. If the first flight is late and your second flight is on a separate reservation, the airline owes you nothing, and a 30-hour trip is a bad place to learn that lesson. I also like to arrive in the daytime. The airport is on the coast, a good drive from the capital and the surf beaches alike, and arriving after a full day of travel in the dark is more tiring than it needs to be.
From the airport to your first bed
The airport is about 45 km from San Salvador and a little closer to the beach towns of the Costa del Bálsamo, the coastal strip around La Libertad. A taxi or pre-arranged transfer to the capital takes roughly 40 to 60 minutes with normal traffic, and a little longer around rush hour. Most hotels and hostels will arrange a pickup for a modest fee, and I recommend doing that for your first night, so there is no negotiating at the kerb while you are tired. Check the fare in US dollars before you set off.
If you have a long wait on the way out, the airport also has a premium lounge. We list the Avianca VIP Lounge at El Salvador International Airport, which sits airside after passport control and security. Its page lists runway views, hot and cold food, shower facilities and Wi-Fi, and its opening hours run roughly from 5 am to 10 pm. I would only book it if your departure leaves you several hours to fill, since the best use of a lounge is a proper shower and a seat before a very long flight home.
When to go: seasons, surf and volcano views
El Salvador has two seasons, not four. The dry season runs from roughly November to April, and the rainy season from May to October. If you are a Singaporean, you will find the rainy season oddly familiar, because the pattern is a hot, bright morning followed by a heavy afternoon downpour that clears by evening. It is not a washout, but it does change how you plan days.
| Months | Weather | Good for | Trade-offs |
|---|---|---|---|
| November to February | Dry, sunny, cooler nights in the highlands | Volcano hikes, coffee-country villages, long beach days | Busiest and priciest period, especially around Christmas and New Year |
| March to April | Hot, very dry, clear skies | Beach holidays; Semana Santa (Holy Week) festivities | Holy Week is crowded and many locals head to the coast |
| May to July | Green landscapes, afternoon storms | Cheaper stays, fewer visitors, lush hiking | Roads and trails can be muddy; plan outdoor activity for the morning |
| August to October | Wettest stretch, occasional tropical systems | Surfing swells on the Pacific coast, lowest prices | Higher chance of weather disruption; flexible tickets are wise |
If I were choosing one window for a first visit, I would aim for late November through early February. The hills are green from the rains, the skies are clear for volcano views, and the Pacific is warm. March and April are better still for pure beach time, but the heat builds and Holy Week turns the coast into a family festival. For surfers, the rainy months bring bigger swells to the Pacific coast, which is exactly why many surf trips are planned for the middle of the year.
One practical note on the weather: because the country is small and mountainous, you get big temperature changes within a short drive. San Salvador can feel warm and sticky, while a village on the Ruta de las Flores at around a thousand metres is distinctly cooler, and a night on the rim of a volcano can need a jacket. Pack for both ends.
Money: dollars, cash and what a day costs
El Salvador adopted the US dollar in 2001, and prices are quoted in dollars everywhere. For a Singapore visitor that is a relief, because there is no currency exchange to fiddle with on arrival and no foreign coins to carry home. You will see Bitcoin mentioned in the news, since the country made it legal tender in 2021, but I would not plan around it. It was changed from a compulsory acceptance rule to a voluntary one in 2025, and in practice you will pay in dollars, either in cash or by card where accepted.
Carry small notes. Many small restaurants, bus conductors, market stalls and taxi drivers do not have change for a twenty, let alone a fifty. ATMs are plentiful in cities and malls but can be sparse in small villages and on the coast, so withdraw before heading to the hills or beach. Cards are accepted at hotels, larger restaurants and shops, but cash is king for pupusa stands, public buses and tips. Tell your bank you are travelling, and keep one backup card in a separate bag.
| Spending style | Typical daily budget per person (US dollars) | What that usually covers |
|---|---|---|
| Backpacker | About 35 to 55 | Dorm bed or basic room, pupusas and set lunches, chicken buses, one paid activity every couple of days |
| Comfortable mid-range | About 90 to 160 | Private room in a good guesthouse or small hotel, restaurant dinners, shuttles or private drivers, one or two tours |
| Treat yourself | From about 220 | Boutique beach or lake hotel, private transport, guided day trips, nicer dinners |
Getting around the country
The roads are surprisingly good for the region, and distances are short. A drive from the capital to the surf coast takes around 45 minutes to an hour, to the Ruta de las Flores about two hours, and to the far eastern beaches perhaps three. That means you can base yourself in one or two places and make day trips, rather than packing and unpacking every night.
| Option | Best for | Rough feel | Notes |
|---|---|---|---|
| Private driver or transfer | Families, first-timers, airport days | Comfortable, door to door | Agree the price in dollars before the journey; most hotels can arrange one |
| Shared shuttle | Backpackers and couples | Fixed routes between popular hubs | Book a day ahead in high season; confirm pickup spots |
| Rental car | Confident drivers who want freedom | Flexible, but demanding on mountain roads | Take photos of the car at pickup; avoid night driving in rural areas |
| Public buses | Adventurous travellers on a tight budget | Cheap, crowded, colourful | Keep valuables close; carry small notes for the fare |
| Ride-hailing app | Within San Salvador and larger towns | Convenient where available | Check which app is active; confirm the plate before you get in |
My advice for a first trip is to hire a driver for the long hops and use walking and short taxi rides within each base. Salvadoran drivers can be assertive on the highways, overtaking on blind curves in a way that will make a Singaporean flinch. Having a calm local driver at the wheel solves that and also gets you stories and restaurant tips for free.
Safety, said plainly
I am not going to pretend this section is not necessary. El Salvador had one of the highest homicide rates in the world not many years ago, and that reputation still colours how people talk about it. The situation has changed a lot since a nationwide security crackdown began in 2022, under a state of exception that the government has repeatedly extended. Tourism officials and many visitors report that streets, beaches and tourist areas feel much calmer than the old headlines suggest. At the same time, the measures are controversial in terms of civil liberties, and conditions can change, so please read your own government's current travel advisory rather than rely on a blog.
From a practical traveller's point of view, I follow a handful of simple habits that make the biggest difference. None of them are unusual, but together they lower your risk of the common problems, which are petty theft and being in the wrong place at the wrong time.
- Stay in established areas. Ask your hotel which neighbourhoods are comfortable to walk in after dark, and take a taxi or ride-hailing car at night rather than walking.
- Keep valuables out of sight on buses, in markets and at crowded beaches, and never leave bags unattended on the sand while you swim.
- Carry ID, leave the original passport. Keep a photo or photocopy for day trips, but have identification on you, since police checkpoints are normal.
- Be calm at checkpoints. Have documents ready, follow instructions and avoid photographing security forces or installations.
- Do not hike remote trails alone. Volcano and national park routes are best done with a registered guide or group, and some require one.
- Respect the sea. Pacific beaches have strong rip currents and heavy shore breaks, and many popular surf beaches have no lifeguards.
Buy travel insurance that covers medical care and evacuation, and read whether it excludes activities such as surfing, volcano hiking or ATV riding. Private hospitals in San Salvador are decent, but anything serious in a rural area means a long ride. Tap water is not recommended for drinking; stick to bottled or filtered water, and be sensible with ice and raw salads from roadside stalls until your stomach settles in.
Where to go: the five areas worth your time
El Salvador's appeal is compact variety. I think of the country as five zones, each of which suits a different kind of traveller. You do not have to see all of them; most one-week itineraries pick three.
1. The surf coast: El Tunco, El Zonte and La Libertad
This is the part of El Salvador that has put the country on the travel map. The coastal strip west of the airport, often called Surf City, holds a string of black-sand beaches with strong waves and a relaxed, sun-baked, flip-flop vibe. El Tunco is the busiest, with a small main street of bars, restaurants and hostels. El Zonte, a little further west, is quieter and friendlier to beginners, and has become something of a digital nomad hangout. La Libertad, the nearby port town, has a pier and a seafood market worth a wander in the morning.
Even if you have never touched a surfboard, this coast is a good place to learn. Lessons are inexpensive, boards are rented by the hour, and the evening scene is built around watching the sunset from a beach bar with a cold drink. If you want a calm sea for swimming, ask locals which beach is safest on the day, and never swim at beaches where flags or signs warn against it.
2. Ruta de las Flores: coffee, murals and food markets
A scenic road winds through highland villages in the west, past coffee farms, waterfalls and hillsides full of flowers in the dry months. The towns have names like Juayúa, Apaneca, Ataco and Nahuizalco, and each has a different character. Juayúa is famous for its weekend food festival, where rows of stalls serve grilled meats, tamales, fried frogs' legs, and sweets in the square. Ataco is known for its murals, craft shops and cafés. Apaneca is the quiet one, with a laid-back feel and good lookouts.
A visit to a coffee farm is worth an hour of your time. Many offer tours that walk you through planting, picking, drying and roasting, followed by a tasting that will change how you think about a cup of coffee. Go in the morning, when the air is cool, and stay for lunch. You can do the whole route in a long day trip from San Salvador or the coast, but sleeping in one of the villages gives you a slower and more atmospheric experience.
3. Volcanoes and Lake Coatepeque
The Santa Ana volcano, known locally as Ilamatepec, is the highest in the country, and the climb ends at a crater rim with a turquoise lake inside. From the top you can see across to the cone of Izalco, sometimes called the Lighthouse of the Pacific because its eruptions once guided sailors. Hikes are done in groups with police or park escorts, usually starting early to avoid cloud and heat. They are moderate rather than technical, but the trail is steep in places, so wear proper shoes.
Nearby Lake Coatepeque fills an ancient caldera and is a favourite weekend spot for Salvadorans. The water is a startling blue-green, you can kayak or swim, and a number of lakeside restaurants serve fresh fish with a view. It is an easy place to build a lazy afternoon after a morning volcano climb.
4. San Salvador and the archaeological sites
The capital is not pretty in the postcard sense, but it rewards a day or two. The historic centre has a cathedral, a national palace and a revitalised plaza; the museums cover everything from Maya heritage to modern art. The hillside suburbs have good restaurants and craft shops. Joya de Cerén, often called the Pompeii of the Americas, is a small farming village preserved under volcanic ash about 1,400 years ago and listed as a UNESCO World Heritage Site. Nearby, the ruins of San Andrés and Tazumal show you pre-Hispanic ceremonial architecture.
If you only have one cultural day, pair Joya de Cerén with San Andrés in the morning, and then have a long lunch in the capital. The sites are modest in scale but make the history tangible in a way that a museum label rarely does.
5. The north and east: Suchitoto, Perquín and the quieter beaches
Suchitoto, a cobblestone colonial town on a hill above a reservoir, is the calm cultural alternative to the beach scene, with art galleries, pretty churches and waterfalls close by. Further north and east, in Morazán, Perquín holds a museum about the country's civil war that is moving and thought-provoking. The eastern beaches, such as El Cuco and Playa Las Flores, are less developed, with fewer services but wider, emptier sand.
| Area | Best for | Suggested time | Base from |
|---|---|---|---|
| Surf coast | Beaches, surfing lessons, sunsets | 2 to 3 nights | El Tunco or El Zonte |
| Ruta de las Flores | Coffee, food, villages, waterfalls | 1 night or a long day | Juayúa or Ataco |
| Santa Ana and Coatepeque | Volcano hike, lake views | 1 night | Santa Ana city or the lake |
| San Salvador and ruins | History, museums, food | 1 to 2 nights | A neighbourhood hotel |
| Suchitoto and the north | Colonial streets, culture, quiet | 1 night | Suchitoto |
What to eat: pupusas and everything around them
If you remember only one word, make it pupusa. It is a thick, hand-patted corn tortilla, griddled and stuffed, most classically with cheese, refried beans or chicharrón, a seasoned ground pork paste. It is served with curtido, a lightly fermented cabbage slaw, and a thin tomato salsa. The experience is a bit like eating a hot, savoury pancake with a crunchy-sour salad on top, and it is eaten with your hands. In many places they cost around a dollar or so each, and two or three make a proper meal.
Look for the variety. A revuelta combines pork, beans and cheese; a loroco pupusa features the flower buds of a Central American vine that has a distinctive green, slightly earthy taste; and some places stuff them with shrimp, spinach or jalapeño. For a Singaporean who loves local hawker food, the pupusería is the closest cousin: a short menu, cooked in front of you, and every shop has a loyal following.
Beyond pupusas, the table is simple and satisfying. Here are the dishes I would not miss, with a note on what to order.
| Dish | What it is | Where to try it |
|---|---|---|
| Pupusa | Stuffed corn tortilla with curtido and salsa | Anywhere; busy stalls are best |
| Yuca frita con chicharrón | Fried cassava with crispy pork | Casual restaurants and market stalls |
| Pan con pollo | A warm chicken sandwich with a rich sauce, tomato and cucumber | Bakeries and street vendors |
| Sopa de pata | A hearty tripe and cow-foot soup | Traditional comedores and weekend markets |
| Mariscos and ceviche | Fresh seafood by the coast | La Libertad and the surf towns |
| Atol de elote | A warm, sweet sweetcorn drink | Morning stalls and village squares |
| Horchata de morro | A creamy, nutty drink made from morro seeds and spices | Street vendors and local cafés |
| Salvadoran coffee | Mountain-grown, smooth and slightly sweet | Ruta de las Flores and city cafés |
Vegetarians can manage with cheese and bean pupusas, fried plantain, beans and rice, and fresh fruit, though meat is central to many dishes and broth often hides pork. Say 'sin carne' when ordering and ask about the filling. If you eat halal, you will have to be careful, as pork is common and halal certification is rare; seafood, vegetables and fruit will be your safest choices.
Staying connected: the eSIM question
A data connection makes a trip like this easier. You will want maps for the long drives, a translation app for conversations that outrun your Spanish, ride-hailing in the capital, and a way to message your hotel and driver. Roaming from a Singapore plan is usually costly, and buying a physical SIM on arrival means an extra errand at a busy airport.
That is where an eSIM helps. We list the Airalo El Salvador eSIM package, which is a digital profile you install on a compatible phone before you leave, so that data is ready the moment you land. The product page notes that your device must be carrier-unlocked and support eSIM technology, and that a stable internet connection is needed to install it. It keeps your regular number for messaging apps, since the eSIM is for data. Check that your phone supports it before you buy, choose a data allowance that fits your trip length, and install it on Wi-Fi at home.
A sample seven-day itinerary
Here is the route I would suggest for a first visit, designed to keep driving short, include variety and avoid a punishing schedule. Adjust it to your arrival time and energy.
| Day | Plan | Notes |
|---|---|---|
| 1 | Arrive, transfer to the surf coast, sunset on the beach | Pre-book the pickup; keep the evening easy after the journey |
| 2 | Surf lesson or beach day at El Zonte; seafood dinner | Sunscreen and a rash vest help; check the surf conditions |
| 3 | Morning in La Libertad's market, then drive to San Salvador | Check into a city hotel; dinner in a leafy neighbourhood |
| 4 | Joya de Cerén, San Andrés and Tazumal, then the historic centre | Start early; carry water and a hat |
| 5 | Drive to the Ruta de las Flores; coffee farm and village stroll | Stay overnight in Juayúa or Ataco |
| 6 | Weekend market if timing allows, then Santa Ana volcano or Lake Coatepeque | Volcano hikes start early; the lake is the relaxed alternative |
| 7 | Return toward the airport; lounge or last-minute shopping before departure | Leave generous time, as traffic near the capital can be heavy |
Adding neighbouring countries
Because the region is compact, it is tempting to stack several countries into one trip. It can work well, but be realistic about border time, and remember that the CA-4 allowance counts days across the group of countries. These are the neighbours I hear about most, along with a little context on the connections we list for them.
| Neighbour | Why combine it | Travel feel | Planning note |
|---|---|---|---|
| Guatemala | Colonial Antigua, Lake Atitlán, Tikal ruins | Long but scenic overland journey, or a short flight | Counts toward the shared 90-day CA-4 allowance |
| Honduras | Copán ruins and Caribbean islands | Overland border crossing in the west | Check the latest safety advice for your route |
| Costa Rica | Rainforest, wildlife and volcano parks | Short flight from San Salvador | Different entry rules; check separately |
| Mexico | Cities, ruins and Caribbean beaches | Flight connections via major hubs | Separate entry formalities |
| Panama | Panama Canal and city stopovers | Common regional hub for flights | Easy to use as a stopover |
If you do continue to Costa Rica, we list tours in San José such as a private bites-and-sights tour and a food-and-culture evening, as well as an airport service at Juan Santamaría International Airport. Honduras and Guatemala have connectivity products too, and Mexico has a much larger selection, from Chichen Itza guided visits to island tours. These are not El Salvador activities, so I mention them only as ideas for building out a wider route.
Culture, etiquette and small things that matter
Salvadorans are warm, polite and a little formal at first. A greeting matters: buenos días, buenas tardes, buenas noches, said to shopkeepers, drivers and hotel staff when you walk in, is a small effort that changes how people treat you. Many locals use 'vos' instead of 'tú', a quirk of Central American Spanish you will hear constantly. If you learn only a handful of phrases, make them 'por favor', 'gracias', 'cuánto cuesta', 'la cuenta, por favor' and 'sin picante'.
Booking what we list for El Salvador
At the time of writing, HolidaySG lists two items for El Salvador, and they are both practical rather than headline attractions. That is deliberate: this is a country where you will mostly be arranging stays and local transport on the ground, and the sensible things to sort in advance are your airport time and your data connection.
| Item | What it is | When it helps |
|---|---|---|
| Avianca VIP Lounge, El Salvador International Airport | Airside lounge with food, showers, Wi-Fi and runway views | A long wait before an overnight or multi-leg departure |
| Airalo El Salvador eSIM package | Data-only digital SIM for your phone | From landing onward, for maps, messaging and ride-hailing |
Both can be booked through HolidaySG, a licensed Singapore travel agency. Tickets and confirmations are emailed after our team confirms your booking, and support is handled by a Singapore-based team via chat or email, in the hours shown in our site footer. Cancellation and refund terms vary by item, so read the conditions on each page before you pay. For anything beyond these two listings, such as accommodation, local tours and drivers, you will arrange them directly or through your hotel.
If you are still working out whether you can travel at all, start with the visa side. Our visa requirements section lets you check destinations by passport, and the flight reservation page explains the dated reservation some applicants need for an embassy file.
Frequently asked questions
Is El Salvador safe for tourists in 2026?
Conditions have improved a great deal since 2022, and many visitors now describe tourist areas as calm. That said, a security state of exception has been in place, and rules and risks can shift. Read your government's current advisory, use reputable accommodation and transport, avoid isolated areas and trails alone, and follow the common-sense habits listed in the safety section above.
Do I need a visa as a Singapore passport holder?
Based on the official sources we follow, Singapore passport holders can enter for tourism without a prior visa under the CA-4 arrangement, for a short stay counted across the four countries. Always verify the current rules, any tourist card fee and any online forms before you fly, since requirements can change.
What currency should I bring?
US dollars. Bring a mix of small notes and coins for everyday purchases, and use a card at hotels and larger restaurants. Withdraw cash in cities before heading to villages and the coast, where machines are fewer.
How many days do I need?
Five to eight days works well for a first visit. With a week you can cover the surf coast, the capital with its ruins, and the Ruta de las Flores without rushing. Add days if you want volcano hikes, Suchitoto or the eastern beaches.
What is the best time of year to visit?
November to April is the dry season, with the most reliable weather for hiking and beach days. May to October is wetter and cheaper, with green landscapes and bigger surf, but expect afternoon storms and plan outdoor activity for the morning.
Can I drink the tap water?
It is best not to. Use bottled or filtered water for drinking and brushing your teeth, and be careful with ice and uncooked food from roadside stalls until you know how your stomach reacts.
Will my phone work, and do I need an eSIM?
Most Singapore phones will work with international roaming, though it can be costly. A data eSIM is a practical alternative if your phone supports it and is carrier-unlocked. Install it before departure on a reliable connection, and keep your normal number for messaging apps.
Is there a direct flight from Singapore?
No. You will connect through at least one other airport, often in the United States, Europe, the Gulf, Panama or Mexico. Plan around total travel time of roughly one and a half days, book on a single ticket where possible, and check transit rules for each stop.
Planning your El Salvador trip?
Check your entry requirements, sort out a flight reservation for your visa file if you need one, and line up your airport lounge and data eSIM before you go. Start with the El Salvador page and build from there.
One last thought. El Salvador is the sort of destination that rewards an open mind and a flexible plan. You will not find the polished infrastructure of a well-trodden route, and some days will be slower than you expected. But you will also find friendly people, memorable food for a few dollars, and landscapes that change every hour's drive. Go with good information, sensible caution and a taste for pupusas, and I think you will wonder, like my friend, why nobody told you sooner.
