Koh Samui Travel Checklist for First-Time Visitors

I went to Koh Samui the first time with a suitcase full of the wrong things and a head full of a brochure. I packed a blazer. I did not pack a dry bag. I assumed the beach I had saved on my phone was walking distance from my room, and it was not, and I found out at 2 pm in the sun with a flat phone battery. Nothing went badly wrong, but I lost a few hours and a bit of money to things I could have sorted out in ten minutes at home. This guide is the checklist I wish someone had handed me, written for a friend who is about to go for the first time.

A quick correction before we begin. Some older write-ups of the island, including an earlier version of this very page, mix Samui up with Phuket. Patong Beach and the Chalong Bay area are on Phuket, a different island on the other coast. Samui sits in the Gulf of Thailand, and the places that matter here are Chaweng, Lamai, Bophut, Maenam and Choeng Mon. I will stick to those.

Before you book anything: what Samui actually is

Samui is one of Thailand's biggest islands, about 21 km long and not much wider, with a single ring road that runs most of the way round the coast. It is not a place where you wander out of your hotel and everything is next door. Distances look small on a map and feel large in a hot songthaew with no air conditioning. The practical result is that where you sleep decides what kind of holiday you have.

The island has an airport of its own, a small open-air affair with a couple of cafes and a very short walk from plane to terminal. Flights come mostly from Bangkok and a handful of other hubs. The other way in is by ferry from the mainland, typically from the Surat Thani side, often as a combined bus and boat ticket. If you are cost-conscious and have time, the ferry route works. If you have only four or five days, fly. Everything else on this checklist assumes a short first trip.

My honest suggestion for most first-timers is five to seven nights. Three nights feels rushed once you count arrival and departure, and ten nights is lovely but better suited to a second visit when you know which side of the island you like.

Visa, passport and arrival paperwork

This is the part people skip and then regret in a queue. Entry rules for Thailand change, so always check the latest official position before you fly. As a general picture, the official facts we hold list a visa exemption for tourism for travellers on Singapore and Indian passports for up to 30 days per entry, with no application needed beyond the digital arrival card, and a tourist e-visa route for people who need a visa or want to stay longer. The e-visa fee we last verified was THB 1,000, with processing of roughly 14 working days, so do not leave it to the last week.

Two things to do at home. First, check your passport validity. Most airlines and immigration desks want at least six months left, and two blank pages is the safe minimum. Second, complete the Thailand Digital Arrival Card online ahead of arrival if it applies to your trip. I do it on the sofa two or three days before departure and screenshot the confirmation, because airport wifi is never as generous as you hope.

If your own passport needs a visa, our visa requirements checker lets you pick your nationality and see the current options for Thailand in one place, including fees and processing times we have verified from official sources. It is the quickest way to find out which of the two groups you are in.

One more thing that catches people out. Visa applications for some countries ask for proof of onward or return travel before they will approve you. If that is you, and you do not want to pay for a fully ticketed flight you may change, we offer a flight reservation service made for visa applications. To be clear about what it is: a reservation document for your application, not an issued airline ticket and not a promise of visa approval. Useful if an embassy form is waiting on a flight itinerary, irrelevant if you are visa-exempt.

The documents and money folder

I keep a single zip-top pouch for the dull but vital things, and I photograph every item in it. Here is what goes in mine for Samui:

• Passport and a saved copy of the data page
• Digital arrival card confirmation (screenshot, saved offline)
• Accommodation address in Thai script, because taxi drivers will ask
• Travel insurance policy number and the emergency line
• Two payment cards from different banks, plus a little baht in cash
• Your booking confirmations for tours and tickets

On insurance, I will be blunt: buy it. Samui has good private hospitals, and they are priced like private hospitals. A scooter slide on a wet road is the classic first-timer injury on this island, and a bill for stitches and a hospital night adds up quickly. Check that your policy actually covers motorbike riding if you plan to hire one, because many standard policies exclude it.

On money, ATMs are everywhere in Chaweng and Lamai, and each one charges a flat foreign card fee on top of whatever your bank adds. Withdraw larger amounts less often rather than small amounts daily. Smaller restaurants, market stalls, massage places and songthaew drivers still prefer cash. Larger resorts, tour operators and malls take cards without fuss.

Choosing a beach side: Chaweng, Lamai, Bophut, Maenam

This is the decision that shapes everything else, so it deserves a table. These are my impressions from several stays, not an official ranking, and you should read them as a feel for each area rather than a promise.

If it is truly your first time and you are travelling with a friend or partner, Chaweng or Bophut is the safe choice. If you have children under six, I would lean Choeng Mon or Bophut because the water is gentler. If you are travelling alone and want to meet people, Lamai has a friendly hostel scene.

What to pack, and what to leave at home

Samui is hot and humid most of the year, and the temperature barely drops after dark. The old checklist on this page suggested sunscreen, a hat and sunglasses, and that is a fine start, but it is not enough. Here is how I would build a bag today.

Clothing. Lightweight cotton or linen, quick-dry swimwear (take two sets so one is always dry), a light rain shell, and one set of smarter clothes that cover your shoulders and knees. That last item matters. Temples, including the Big Buddha complex, expect modest clothing, and some of the better restaurants appreciate it too. Leave the blazer at home. I mean it.

Footwear. Flip-flops for everything, one pair of closed shoes or sandals with grip for jungle tours and slippery boat decks, and nothing with heels. Many tours will give you water shoes for kayaking, but check.

Sun and bugs. Reef-safe sunscreen (national park islands ask for it), a hat, sunglasses, and a repellent with a decent concentration of the active ingredient. Evenings near the waterfall trails and in jungle-edged villas are mosquito territory.

Electronics. Most sockets in Thai hotels take both flat two-pin and round two-pin plugs, but pack a universal adapter anyway. Bring a waterproof phone pouch, a small power bank for long boat days, and a charging cable you do not mind losing.

Health. Rehydration salts, plasters, anti-diarrhoea tablets, motion sickness pills (speedboats can be bumpy), your regular prescriptions in original packaging, and a basic antiseptic. The pharmacies on the island are good, but you do not want to hunt for them while seasick.

Packing light. A rolling case is fine for the airport and hotels, but a soft duffel is easier on a ferry or in the back of a pickup. I travel with a carry-on and a small day bag. Laundry is cheap and quick in Samui, so a week of clothes can be five days of clothes.

Connectivity: the first thing to sort at the airport, or before

Arriving with working data makes everything else easier. Maps, translation, taxi bookings, the arrival card and your tour vouchers all live on your phone. I used to queue for a physical SIM at the airport. Now I install an eSIM before leaving home and switch it on after landing. It is less fuss, and I do not carry a tiny card that I then lose. If you want to see what we list, there is a Thailand unlimited data eSIM from S$12.43. Check that your phone supports eSIM before you buy, because older or carrier-locked models do not.

How to get around once you land

Getting around is the single biggest source of first-timer grief on Samui, so here is the plain version.

Airport taxis and fixed-price counters. Easy, slightly pricey, and absolutely fine on the day you arrive when you are tired. Ask for the price before you get in.

Songthaews. The converted pickup trucks that circle the ring road. They are cheap and a good way to feel the island, but they are slow, the fares are not always posted, and they mostly stop running by evening. Agree the fare before you hop on, and carry small notes.

Ride-hailing and private cars. App-based rides exist but coverage is patchy compared with a big city, and some areas are controlled by local taxi cooperatives. Hotel desks can arrange a private car at a stated price. For a first visit I usually book a driver by the day for the loop around the island.

Scooters. Everyone hires one and many people crash. If you have never ridden a motorbike, a Samui hillside in a rainstorm is not the place to learn. If you do ride, wear a helmet (it is required), carry your licence with the right category, check your insurance covers it, and take photos of the bike before you leave the shop so there is no argument about scratches.

The things worth doing on a first trip

I will keep this honest. Samui is not about ticking off forty attractions. It is about choosing three or four experiences you will remember and leaving the rest of the days for the beach. Here is how I would shape a week.

Angthong Marine National Park. If you only do one boat day, do this. The park is a cluster of limestone islands northwest of Samui, with an emerald saltwater lagoon, kayaking, snorkelling and a short but steep climb to a viewpoint that earns the photograph. You can go by big boat from S$37.61 or by speedboat from S$65.63. The big boat is slower, cheaper and more social. The speedboat is quicker and gets you more time on the water. A national park fee is collected in cash on arrival, so keep some baht ready. The best months for calm seas and clear water tend to be roughly November to February, with the shoulder months still good.

Koh Tao and Koh Nangyuan. A longer boat day for snorkelling people. The reefs around Koh Tao are the draw, and Koh Nangyuan, three small islands joined by a sandbar, is the postcard stop. It is a full day, about eight to ten hours with transfers, so go to bed early the night before. Our Koh Tao and Koh Nangyuan speedboat day starts from S$65.63.

Koh Tan and Koh Mudsum (Pig Island). Shorter and gentler, and great if you are travelling with children. You snorkel on the coral near Koh Tan and then visit Koh Mudsum, where the resident pigs roam the beach. Tides can affect beach access at Koh Mudsum, so listen to your guide. Price starts from S$53.01, via our Koh Tan and Koh Mudsum speedboat tour.

Elephant sanctuary. I want to say something here, because elephant tourism is a tricky area. The sanctuary we list is built around feeding, mud-bathing and watching rescued elephants rather than riding them, which is the part I look for. Wear clothes you do not mind getting muddy and bring a towel and swimwear. Roughly five to six hours with transfers. See the Elephant Jungle Sanctuary Samui page, priced from S$24.26. Whatever you choose, ask yourself whether the animals look like they have a choice. If not, walk away.

Jungle safari and waterfalls. The inland half of the island is where Samui turns into rainforest, with waterfalls, rubber plantations and the odd roadside monkey. A 4x4 tour usually stitches in the Big Buddha, the Namuang waterfall, the Grandfather and Grandmother rocks (Hin Ta and Hin Yai) and a viewpoint, and takes most of a day. Take a look at the Samui jungle safari 4x4 tour, from S$52.22.

ATV. If you want adrenaline in a smaller dose, the two-hour ATV ride goes through mountain trails and coconut groves and includes transfers. It is dusty and loud and a lot of fun, and not ideal for anyone with back problems. See the 2 hour ATV experience, from S$91.53.

Go-karting. Not what you expect from a beach island, but EasyKart at Chaweng Lake is a reliable family evening or rainy afternoon. Karts are matched to age and height, safety gear is provided, and you need no experience. Allow an hour to an hour and a half. EasyKart Samui starts from S$26.57.

Muay Thai. Watching a live Muay Thai evening is a very Thai thing to do, and it is not as intimidating as it sounds. The fights, the ritual dance before each bout and the music make it feel like theatre. Samui has two main stadiums. Samui International Stadium runs shows on Sunday, Tuesday and Friday nights, starting at 21:00, with tickets from S$55.30. Samui Phetch Buncha Boxing Stadium runs on Monday, Wednesday and Saturday, also at 21:00, from S$59.08. Check the schedule for your dates before you plan the rest of your evening. Both are ringside experiences and the front rows are close enough to hear every impact, so think twice about bringing very young children.

Temples and the free-to-wander sights

Not everything needs a ticket, and some of the best hours I have spent on Samui cost nothing. The Big Buddha at Bophut is the best known landmark, a seated golden figure near the airport, visible from the sky as you land. Wat Plai Laem, not far from Chaweng, has a striking multi-armed statue of Guanyin beside a lake and is gentler and quieter. Hin Ta and Hin Yai, the two rocks on the southern coast, are a short stop that people find either funny or charming. Fisherman's Village in Bophut has a Friday-night walking street I enjoy, with grilled seafood, small stalls and live music.

A small note on temple behaviour that I always wish I had been told earlier. Cover your shoulders and knees, remove shoes at the door, keep your feet pointing away from Buddha images when you sit, and keep your voice low. Nobody will lecture you, but the small courtesies get noticed.

Eating on Samui: what to try first

Food is a real reason to come. Most of the best meals I have had on the island were not at the places on the postcard strip. Look for a plastic stool, a cluster of locals and a menu with fewer than ten dishes.

Start with the classics: green curry, pad krapow with a fried egg, tom yum goong, fresh grilled fish with a lime and chilli dip, and mango sticky rice when mangoes are in season. Southern Thai cooking tends to be spicier and more turmeric-heavy than the central Thai dishes you may know from Thai restaurants back home, so if you cannot take heat, say mai phet (not spicy) and then expect it to still be warm.

Night markets are the easiest way to taste widely without committing to one plate. The Lamai and Chaweng night markets are both good, and the Fisherman's Village Friday street is a more polished version. For seafood by the beach, expect to pay more for the sunset view, and check the price per 100 grams for fish before you order, so the bill does not surprise you.

A word on water. Do not drink from the tap. Bottled water is cheap, and most hotels provide a bottle or two. Ice in restaurants is usually made from purified water, so you can generally accept it without worry. Smoothies and fruit shakes are worth every baht.

When to go: weather and seasons

This changes more with the year than most people expect, and it works differently from Phuket and the Andaman side. The Gulf coast has its own pattern, with its wettest stretch usually landing later in the year than the Andaman coast. As a general picture, expect the following, though any given year may surprise you.

Our country notes put the cool and dry stretch at roughly November to February, with the monsoon rains from around June to October on the wider Thai calendar. Samui's own rainy peak can arrive later than that, so if you are going in the last quarter of the year, check a recent forecast and keep your plans flexible for boat trips, which can be moved when the sea is rough.

A budget that matches reality

Prices change, so treat the numbers below as a rough planning guide rather than a quote. Our own country notes suggest planning around THB 1,500 to 5,000 per person per day for Thailand as a whole. On Samui, the high end is easy to reach if you eat at beach restaurants and book several tours, and the low end is possible if you stay in simple rooms and eat at markets.

A good rule: add ten percent for things you did not plan. Park fees, tips, an extra drink, a taxi that costs more than you expected. It always ends up being something.

A sample five-day plan for first-timers

This is the loose shape I would give a friend. Swap days around to follow the weather, and do not feel you must fill every hour.

Day 1, arrive and slow down. Land, check in, walk the beach, eat somewhere close, sleep early. Nothing else.

Day 2, the island loop. Big Buddha in the morning, Wat Plai Laem, Fisherman's Village for dinner. A hired driver or the 4x4 safari makes this simple.

Day 3, the big boat day. Angthong Marine National Park. Back by late afternoon, a massage, an early night.

Day 4, beach and a show. Sleep in, spend the day on the sand, then a Muay Thai evening after dinner.

Day 5, animals or adrenaline. The elephant sanctuary in the morning if you have a flight late in the day, or the ATV ride, or simply one last swim.

Travelling with children or older parents

I have done Samui both with a friend and with my parents, and the two trips could not have been more different. With children, the water matters most. Pick a bay with gentle, shallow water and a short walk from your room to the sand, because a long hot walk with a tired five-year-old ends every plan. Choeng Mon and the quieter parts of Bophut work well. Build a nap or a pool hour into the middle of each day, and keep boat trips to the shorter ones, since eight to ten hours on the water is a long time for small legs.

With older parents, the issues are heat, steps and uneven ground. Many of the best viewpoints involve stairs, and the Angthong climb is steep, so tell them they can skip it and wait at the beach with a cold drink. Choose a hotel with a lift or ground-floor rooms if stairs are a problem, and book a private driver rather than relying on songthaews. Evening shows like Muay Thai start late, so check whether that suits your group before you commit.

Rainy-day and evening ideas

Even in the best months a shower can arrive without much warning, and a travel plan that depends on blue sky all week will let you down. Keep a few indoor or covered options in your pocket. A long Thai massage costs far less than back home and takes up a whole afternoon. A cooking class gives you something to take home. Go-karting at Chaweng Lake is a good option when the weather clears for an hour or two. Cafes along the Bophut shoreline are pleasant with a book while the rain passes.

For evenings, the choice is wider than people expect. Walk the Friday street in Fisherman's Village, share a plate of grilled prawns at a night market, take in a Muay Thai bout, or just sit on the sand with a cold coconut. If you plan to be out late, agree a price with your driver before you set off, because getting home after the songthaews stop is where visitors pay the most.

Small mistakes to avoid

• Booking tours for every day. Leave at least two days empty for weather and tiredness.
• Leaving the national park fee out of your cash plan. It is paid on the spot.
• Renting a scooter without a licence or insurance. A fine or an uncovered claim spoils a trip.
• Assuming everything is walkable from your hotel. Check the map distance, then add heat.
• Forgetting a dry bag for boat days. Phones and speedboats do not mix.
• Skipping the sun. The haze fools you, and a burnt first day is hard to recover from.
• Changing all your money at the airport. Rates there are rarely the friendliest.

Safety, scams and common sense

Samui is a relaxed and generally safe island, and most visitors have no trouble. A few sensible habits go a long way. Keep valuables in your hotel safe, carry a copy rather than the original of your passport on day trips, and lock your door even when you are inside. Be wary of anyone who approaches you at a tourist spot offering a very cheap tour, and check the operator and the inclusions before paying. Never leave your bag unattended on the beach while you swim. If you rent a scooter, photograph it before and after.

Jellyfish can appear in some seasons, so look for warning flags. In rough weather, take red flags seriously. Rip currents are real on certain stretches. The sea looks calm and then it is not.

Our country notes also suggest sharing your itinerary with family at home, keeping digital and physical copies of your passport, and having an eSIM or local SIM working on arrival so you can reach emergency services. That advice is sensible anywhere, and Samui is no exception.

Frequently asked questions

Do I need a visa for Koh Samui?

It depends on your passport. Based on the official facts we hold, travellers on Singapore and Indian passports can enter Thailand for tourism visa-free for up to 30 days per entry, and other nationalities may need a tourist e-visa. Rules change, so confirm on the visa requirements checker before you book.

What is the best time to visit Koh Samui?

The cooler, drier months between December and February are the most comfortable for most visitors, and boat days are usually at their best from roughly November to February. The wetter months can still be enjoyable, but plan with flexibility.

How many days do I need on Koh Samui?

Five to seven nights suit a first visit. Three nights feels short once you count travel, and ten gives you room for several boat days and slow beach time.

Is it safe to rent a scooter?

It is the most common way visitors get hurt on the island. If you are an experienced rider with a valid licence, a helmet and insurance that covers motorbikes, it can work. If you are new to riding, use a driver or a tour with pickup instead.

Can I book Muay Thai tickets in advance?

Yes. Samui International Stadium and Samui Phetch Buncha Boxing Stadium both list tickets with HolidaySG, and their fight nights fall on different days of the week, so check which venue fits your dates before booking.

Do I need to pay extra at Angthong Marine National Park?

Yes. A national park entry fee is typically paid in cash at the park on the day, in addition to the tour price, so keep some baht aside.

What should I wear at temples?

Cover your shoulders and knees, remove your shoes before entering, and keep your voice low. A light scarf or shirt in your day bag solves it.

Do I need a flight reservation for a visa application?

Some visa applications ask for proof of onward travel. If yours does, our flight reservation service provides a reservation document for the application. It is not an issued ticket and does not guarantee approval.
