The first time I put my face in the water off Sanur, I nearly drank half the Bali Strait. I had read three articles, watched a dozen videos and still managed to fog my mask, forget to breathe through my mouth and panic when a shoal of silver fish swept past my elbow. Then something clicked. The noise of the beach dropped away, my breathing slowed, and below me a whole busy neighbourhood of coral, sea cucumbers and striped damselfish carried on as if I were not there. I have been chasing that quiet ever since.
This guide is what I wish someone had handed me before that first trip. It covers where to snorkel in Bali, which spots suit beginners and which ones demand respect, when the water is clearest, what a day out realistically costs in Singapore dollars, and the small habits that keep you safe and your holiday photos sharp. I have also added the practical bits Singapore travellers keep asking us about: entry rules, flights, transfers and how to stitch a snorkelling day into the rest of your trip.
Bali's dry season, roughly April to October, gives the calmest seas and the best visibility. Nusa Penida is the headline act for manta rays and dramatic cliffs, Amed is the gentle choice with a wreck close to shore, Nusa Lembongan and Sanur suit first-timers, and Menjangan in the northwest is the quiet, clear-water escape. Boat tickets from Sanur start from about S$8 one way, and a guided snorkelling safari from the Sanur side starts from around S$31.
Why Snorkelling in Bali Is Worth Planning Properly
Bali has a reputation for temples, rice terraces and beach clubs, and snorkelling sometimes gets treated as an afterthought, something you tick off on a free afternoon. That is a mistake. The island sits at the edge of the Coral Triangle, the most biologically rich marine region on the planet, and even a casual swim in the right spot can show you more species in an hour than most places manage in a week.
The trouble is that Bali's coastline is wildly uneven. Some beaches are lovely for sunsets and useless for snorkelling: murky, wave-battered, or crowded with surfers. Others, sometimes only twenty minutes down the road or a short boat hop away, are glassy and full of life. Choosing the right place and the right month matters far more than gear or experience. I have watched confident swimmers have a miserable morning at the wrong beach, and nervous first-timers have the day of their lives at the right one.
So before booking anything, it helps to understand the shape of the options. Broadly, Bali snorkelling falls into four groups: the island-hopping trips from the southeast (Nusa Penida and Nusa Lembongan), the shore-entry spots on the east coast (Amed, Padang Bai and Candidasa), the sheltered lagoon-style stops around Sanur and Tanjung Benoa, and the remote northwest corner at Menjangan. Each has its own personality, and I will take them in turn.
The Main Snorkelling Areas at a Glance
If you only skim one section, make it this one. The table below puts the major areas side by side so you can match them to your comfort level, your base in Bali and your appetite for early starts.
| Area | Character | Getting there | Best for | Watch out for |
|---|---|---|---|---|
| Nusa Penida | Dramatic cliffs, mantas, clear blue water | Fast boat from Sanur, about 30 to 45 minutes | Confident swimmers, bucket-list wildlife | Strong currents, choppy crossings |
| Nusa Lembongan | Sheltered bays, coral gardens, mangroves | Fast boat from Sanur | First-timers and families | Busy boats at midday |
| Amed | Calm, black-sand shore, shallow wreck | Road transfer to the east coast, long day | Relaxed shore snorkelling | Rocky entry, long drive from the south |
| Sanur | Shallow reef flats and protected water | Right on the southeast coast | Absolute beginners, short outings | Tide changes affect depth and clarity |
| Tanjung Benoa | Water sports and marine tours | South, near Nusa Dua | Mixed groups wanting activities | Busy and commercial |
| Menjangan Island | Clear water, wall dives, quiet reef | Northwest Bali, long road journey | Photographers, those with spare days | Distance from the south |
Nusa Penida: Mantas, Cliffs and a Little Respect for the Current
Nusa Penida is the one everyone talks about, and for good reason. You leave Sanur on a fast boat, spend half an hour bouncing across the Bali Strait, and step off onto an island that feels like it belongs on a different planet: limestone cliffs dropping straight into water so blue it looks edited. The snorkelling here is the most dramatic in the region.
The star turn is Manta Point, a cleaning station where manta rays glide in to be groomed by small fish. Seeing a creature with a wingspan wider than a small car pass beneath you in total silence is the sort of thing that rearranges your sense of scale. Sightings are common but never guaranteed, and I have been out when the mantas simply did not show. Treat them as a bonus rather than a promise, and the rest of the day will still be wonderful.
Crystal Bay is the calmer cousin. The water is clearer, the coral is healthy, and the beach makes a pleasant lunch stop between swims. Further along, spots such as Toyapakeh and the waters around the small offshore islets bring in schooling fish and the occasional turtle. Guides here are worth their fee. Currents around Penida can switch from gentle to powerful with little warning, and a good guide reads the water for you, tells you where to enter and where to get out, and keeps a boat close by.
If you are a nervous swimmer, I would not make Penida your first snorkel. Do a gentle outing at Sanur or Lembongan first, get your breathing and mask routine sorted, and then step up. If you are comfortable in open water, wear a flotation vest anyway. It costs nothing, makes floating effortless, and lets you watch the fish instead of thinking about your legs.
Many travellers book the island as a guided day from Bali, which bundles the boat, the driver on land and the snorkel stops. Others buy a fast boat ticket and organise their own scooter or driver. Both approaches work, and I will compare the costs further down.
Nusa Lembongan and the Blue Lagoon: The Friendly Side of the Strait
Hop a little further across the water and Nusa Lembongan feels like a softer, gentler version of its bigger neighbour. The coastline is dotted with sheltered bays, there are mangrove channels you can drift through, and the snorkelling spots tend to be easier. The Blue Lagoon and the nearby coral gardens are classic first-timer territory: clear shallow water, a lot of colour, and relatively little drama.
This is where I would send a family with children, or a group with mixed confidence. The water is usually calmer, the boats are used to beginners, and you can spend a long time drifting over coral without ever feeling out of your depth. Turtles are regularly spotted around the seagrass and reef edges, and I have counted more than a dozen species of reef fish on a single lazy swim.
A combined outing that touches both islands is a popular way to see more in one day. The cruise below visits Nusa Penida and Nusa Lembongan, with time at the water in between. It is a sensible compromise if you cannot decide between the dramatic and the gentle.
One practical note: both islands get busy from late morning, when the day-trip boats all arrive together. If you can choose, join an early departure. The water is calmer, the light is better for photos and the crowds are thinner.
Amed: Calm Water and a Wreck Close to Shore
Amed is not a single beach but a long string of fishing villages along Bali's east coast, with black volcanic sand, wooden jukung boats pulled up on the shore, and Mount Agung looming behind. For snorkellers it offers something the southern islands rarely do: you can walk straight into the sea from the beach and be over coral within a few strokes.
The best-known site is the Japanese wreck near Jemeluk and Lipah, a shipwreck from the Second World War lying in shallow water close to shore. It is overgrown with coral and ringed with fish, and it is calm enough that I have seen nervous swimmers spend an hour over it, entranced. Visibility is usually good in the dry season, though it softens when swells arrive.
The honest downside is distance. Amed is a long drive from the southern tourist belt, and a day trip means hours in a vehicle. If you are short on time, it is better to stay a night or two on that coast, wake to flat morning water and snorkel before breakfast. It also pairs nicely with a sunrise outing on Mount Batur, which sits not far inland.
Sanur and Tanjung Benoa: Easy Water Close to Home Base
Sanur gets overlooked because it is gentle and a little sleepy, but that is exactly its strength. The reef flats here are protected, the water is shallow and the pace is slow. It is also the departure point for most boats to the Nusa islands, so many travellers pass straight through without ever swimming here.
A guided half-day outing from the Sanur side is the most relaxed way to learn. You get a mask that fits, a guide who watches your breathing, and a handful of stops that cover different bits of reef. Tanjung Benoa, near Nusa Dua, is the commercial cousin: banana boats, parasailing and jet skis jostle alongside snorkelling and turtle-island trips. It is not the place for solitude, but it works when your group wants a mix of activities, not just fish.
Pricing note: some water sport products here are sold separately for Indonesian ID holders and for non-Indonesian visitors, so pick the option that matches your passport. Singapore travellers should choose the non-Indonesian version.
Menjangan Island: The Quiet Corner in the Northwest
If you have a spare couple of days and want the clearest water Bali offers, head to the northwest. Menjangan Island sits inside a national park, and the reef there drops off in dramatic walls close to the shore. Visibility is often superb, the crowds are thin, and the whole place feels a world away from the southern traffic.
The trade-off is simple: it is far. Reaching it means a long road journey from the south, and most travellers break the trip with a night in the north. I would only add it if snorkelling is the centre of your holiday, or if you already plan to explore Bali beyond the southern beaches. For a short break, the Nusa islands deliver more reward for the travel time.
The Best Time of Year to Snorkel in Bali
Timing shapes your experience more than any other single choice. Bali has a dry season and a wet season, and while you can snorkel year-round, the quality shifts noticeably.
| Months | Season | Sea and visibility | What to expect |
|---|---|---|---|
| April to June | Early dry season | Calm and clear | Great all-round conditions, fewer crowds than July |
| July to September | Peak dry season | Generally clear, can be breezy | Busiest months, book boats and tours early |
| October | Late dry season | Good, sometimes warmer | Pleasant shoulder period |
| November to March | Wet season | Variable, rain can cloud water | Cheaper stays, choose sheltered spots and be flexible |
The dry window from April to October is the sweet spot, and the climate notes we keep on file for Indonesia say the same: warm year-round, with the wetter months running from about November to March. Temperatures sit in the high twenties to low thirties, so water is comfortably warm without a wetsuit for most people, though a thin rash vest keeps the sun off your back and adds a little warmth on long swims.
Time of day matters too. Mornings usually bring flatter water and better light. Winds tend to pick up in the afternoon, and by then the day boats have churned up the shallows. I always book the earliest slot I can stomach, even when it means a pre-dawn alarm.
Manta sightings around Penida are possible through much of the year, but nobody can promise a particular day. If seeing them is your priority, give yourself more than one chance rather than staking everything on a single morning.
How Much Does Snorkelling in Bali Cost?
Costs vary with how much you want organised for you. A guided half-day and a full island adventure sit at very different price points, and the cheapest route is often a boat ticket plus self-guided exploring. The figures below are starting prices shown on our site in Singapore dollars and can move with season and date, so treat them as a planning guide rather than a quote.
| Option | What it covers | Starting price (per person) | Good fit for |
|---|---|---|---|
| Fast boat ticket to Nusa Penida | Crossing from Sanur, you organise the rest | From about S$8 to S$13 one way | Independent travellers, scooter riders |
| Guided snorkelling safari, Sanur side | Guide, gear and several stops | From about S$31 | Beginners, short on time |
| Two-island fun day cruise | Day on the water around Penida and Lembongan | From about S$47 | Those who want variety without planning |
| Nusa Penida day tour from Bali | Full day with transfers and sightseeing | From about S$67 | First visit to Penida |
| Speedboat beach day trip, guided | Boat, guide, island stops | From about S$116 | Travellers wanting a more private feel |
Beyond the headline price, budget for the extras that always creep in: a reef-safe sunscreen, a waterproof phone pouch, tips for the crew and guide, lunch if it is not included, and park or entry fees at some stops. Read the product page carefully for what is covered, because inclusions differ between operators.
As a rough rule, I tell friends to leave a little breathing room in the budget. Spending slightly more on a well-reviewed guided outing is usually wiser than saving a few dollars and ending up on a crowded boat with ill-fitting gear.
Getting to Bali, and Getting Around Once You Land
From Singapore, Bali is a short flight of under three hours, which is a big part of why it is such an easy snorkelling trip for us. Most visitors land at Ngurah Rai International Airport near Kuta and then head to their base: Sanur for the boats, Canggu or Seminyak for surf and cafes, Ubud for rice fields, Uluwatu for cliffs.
If you do not yet have flights confirmed and need a booking on paper for a visa application, our flight reservation service can help arrange a reservation for that purpose. It is a reservation to support your paperwork, not an issued ticket, so read the details before you rely on it.
Once you land, a pre-booked airport transfer saves the haggling and the jet-lag confusion. Distances from the airport are short by any standard: roughly 45 to 60 minutes to Uluwatu, around 30 to 45 minutes to Canggu, and less to Kuta or Jimbaran depending on traffic. Traffic is the wild card in southern Bali, so always allow extra time on the way back to the airport.
For the boats, base yourself in or near Sanur the night before an early departure. Harbour pickups can also be arranged from many hotels, and several of our boat products include or can be combined with a harbour transfer. If you plan to visit more than one island, a private car charter on land makes a long day a lot easier than negotiating with drivers one after another.
Entry Rules for Singapore and Other Travellers
Entry requirements change, so always check before you fly. As things stand in our verified notes, Singapore passport holders enjoy visa-free entry to Indonesia for stays of up to 30 days, thanks to the ASEAN exemption, which is why Bali is such a spontaneous trip for us. Visitors from many other countries, including India, can use the visa on arrival or the electronic version, which our records list at around IDR 500,000 with a 30-day stay.
| Option | Who it suits | Fee noted | Maximum stay | How you get it |
|---|---|---|---|---|
| ASEAN visa exemption | Singapore and other ASEAN passport holders | Free | 30 days | At immigration on arrival |
| e-Visa on Arrival | Eligible nationalities, including India | About IDR 500,000 | 30 days | Apply online before departure |
| Visa on Arrival (airport counter) | Same eligible nationalities | About IDR 500,000 | 30 days | Buy at the arrival counter |
Our visa requirements pages list the current rules by passport and destination, and they are the first place to check if you are travelling on a passport other than Singapore's. Make sure your passport has enough validity left, carry proof of onward travel, and keep digital copies of everything. Rules and fees can change, so confirm against the official source before you go.
What to Pack and What to Leave on the Boat
Most operators provide masks, snorkels and fins, and many add flotation vests. Even so, I take a few things of my own, and the list is short.
A mask that fits properly beats everything else. If you are particular, buy your own before you travel, because rental masks vary and a leaking mask ruins a good reef. Test it on dry land by pressing it to your face without the strap and sniffing in gently. If it holds, it seals. A little anti-fog gel, or a tiny dab of baby shampoo rubbed on the inside and rinsed lightly, prevents most fogging.
A long-sleeved rash vest and reef-safe sunscreen protect your back, which takes the brunt of the sun while you float face-down. Bali's equatorial sun is fierce, and I have seen more ruined holidays from burnt shoulders than from anything under the water. Add a hat and sunglasses for the boat ride, a dry bag, a towel, a refillable water bottle, and a little cash for tips and snacks.
For cameras, a waterproof pouch rated for your phone and a wrist strap are enough for most people. Do not trust a cheap pouch with an expensive phone. Test it with a tissue inside, submerged in a sink, before you board.
| Item | Why it matters | Provided? |
|---|---|---|
| Mask, snorkel, fins | The basics for any swim | Usually, check the product page |
| Flotation vest | Makes floating easy and safer | Often available on request |
| Rash vest or thin top | Sun and warmth protection | Bring your own |
| Reef-safe sunscreen | Protects skin and coral | Bring your own |
| Waterproof phone pouch | Photos without a drowned handset | Bring your own |
| Cash for tips and snacks | Crew, guides, warung stops | Bring your own |
What You Might See Beneath the Surface
The sea life is the reason you came, so here is what to look for. On the reefs you will find parrotfish crunching coral, butterflyfish in pairs, bannerfish, wrasse in every colour, and the ever-popular clownfish tucked into their anemones. Look closely at the sand for garden eels and small flatfish that vanish when you drift too near, and under ledges for the hidden shapes of moray eels.
Sea turtles show up regularly, especially in seagrass beds around Lembongan and parts of the Penida coast. Stay calm, keep your distance and never chase them. They surface to breathe, and a swimmer crowding them keeps them from doing so. Reef sharks are rare in the usual snorkelling sites and harmless to people, while mantas, as noted, are the big prize at Penida.
On wreck sites like Amed's, expect large schools of small fish swirling around the structure, with coral growing in layers over the hull. Early morning is the best time to catch them active, before the water clouds with swimmers.
| Marine life | Where you are most likely to see it | Tip |
|---|---|---|
| Manta rays | Manta Point, Nusa Penida | Stay on the surface and keep calm |
| Sea turtles | Lembongan and Penida seagrass areas | Never touch or chase |
| Clownfish and reef fish | Most reef sites | Look near anemones and coral heads |
| Wreck fish schools | Amed wreck | Go early for clearer water |
| Mushroom coral and sea fans | Menjangan walls | Float above, keep fins away |
Safety, Currents and Looking After the Reef
Snorkelling is gentle, but the sea is still the sea. Most incidents come from the same handful of causes: ignoring currents, overestimating swimming ability, burning in the sun, and fatigue. A little respect prevents nearly all of them.
Be honest about your swimming
If you are not a strong swimmer, say so. Operators would far prefer to hand you a vest and keep you close than find out mid-trip. A flotation device is not a sign of weakness. It lets you rest, breathe easily and actually enjoy the view.
Respect the current
Around Nusa Penida in particular, currents can sweep you off course quickly. Listen to the briefing, keep your guide in sight, and if you feel yourself drifting, signal early rather than fighting the water. Swim across a current, not against it.
Protect the coral
Never stand on coral, touch it or kick it with your fins. Even a light brush can kill a colony that took decades to grow. Wear reef-safe sunscreen, avoid feeding fish, and take every scrap of rubbish back with you. The reefs you admire today depend on that kind of care.
Health and common sense
Drink water, eat before you go, and avoid heavy alcohol the night before an early boat. If you have asthma, heart or ear problems, ask your doctor before booking. Travel insurance that covers water activities and medical evacuation is worth having, and our notes for Indonesia recommend it for every trip.
Wear a flotation vest if unsure. Keep the boat and guide in sight. Do not touch marine life. Reapply sunscreen on the boat, not in the water. Surface and rest at the first sign of fatigue.
Sample Itineraries: Fitting Snorkelling Into Your Bali Trip
Most of us do not have weeks, so here are three ways I would shape a trip depending on your time and appetite. They are guides, not rules, and every one leaves slack for rain, tired legs and long lunches.
A relaxed long weekend, three days
Land, transfer to Sanur and settle in. Day two is your guided snorkelling outing on the Sanur side, followed by an evening stroll and dinner by the beach. Day three can be a slow morning, a final swim and an easy afternoon before your flight home. It is gentle, forgiving and ideal if you are travelling with children or just want to decompress.
Five days with an island day
Spend your first night near Sanur, then take an early fast boat to Nusa Penida or a two-island cruise on day two. Rest the next day with a cultural morning in Ubud, perhaps the Monkey Forest or a dance performance, and keep a day for the east coast or a sunrise volcano ride. Our verified itinerary notes suggest that a mix of water, culture and one adrenaline activity keeps a trip balanced.
Seven days for the keen snorkeller
Split your week between the south and the east. Begin with Sanur to find your feet, take the Nusa islands for two days, then drive to Amed for a pair of mornings over the wreck and the shore reefs. If you have energy left, add Menjangan on your way through the north. This is the version that rewards you with the most variety, though it asks for more driving.
| Trip length | Suggested base | Snorkelling plan | Pace |
|---|---|---|---|
| 3 days | Sanur | One guided half-day on the Sanur side | Easy |
| 5 days | Sanur and Ubud | One Nusa island day plus a gentle swim | Moderate |
| 7 days | Sanur, Amed, then north | Two Nusa days, Amed wreck, optional Menjangan | Active |
Beyond the Reef: What to Do Before and After
A snorkelling trip is better when you do not spend every hour in the water. Bali packs a remarkable amount into a small island, and it rewards a bit of variety.
Ubud, an hour or so inland, is the cultural heart, with rice terraces, workshops and dance evenings. A morning in the Sacred Monkey Forest is a pleasant counterpoint to a day at sea, as long as you keep your belongings zipped away from the macaques. Food lovers will enjoy an evening street food or night market tour, which tends to run three to four hours and gives you a crash course in Balinese flavour.
For a splash of adventure, there are river rafting, quad biking and volcano jeep options, plus helicopter flights for a bird's-eye view of the coast. Seafood dinner on Jimbaran Bay at sunset is a Bali classic, and the beach barbecue ritual of picking your catch and watching it grill on coconut husk fires is hard to beat after a salty day out.
Whatever you choose, leave an unscheduled half-day. Some of my best Bali memories came from a missed turn, a roadside warung and a conversation I would never have planned.
Booking Smart: Tips From Many Trips
After a lot of mornings on Bali's boats, a few lessons keep repeating themselves, and they are worth passing on.
Book popular departures ahead in the dry season, especially July to September, when seats on fast boats and day tours fill early. Pick morning slots. Read the inclusions list, because some tickets cover only the crossing while others bundle lunch, gear and a guide. Check the meeting point and the pickup time before you pay, since harbour mix-ups are the most common cause of missed boats.
Keep your plans flexible around weather. Rough seas can cancel crossings, and the safest approach is to avoid cramming a snorkelling day right before a flight home. At HolidaySG, bookings made on our site are confirmed by our team before your e-tickets are emailed, so give yourself time between booking and travel rather than leaving it to the last minute.
Also remember the small things that affect comfort: take motion-sickness tablets if you are prone to it, because the Strait can be lively, sit near the back of the boat where the ride is smoother, and eat something light first.
Start with a guided snorkelling outing on the Sanur side, then add a boat to the islands, an airport transfer and a few things to do on dry land. Our team confirms each booking before your e-tickets are emailed.
See Bali snorkelling tripsFrequently Asked Questions
Is snorkelling in Bali suitable for beginners?
Yes, as long as you choose the right place. Sanur, Nusa Lembongan and guided half-day outings are well suited to first-timers. Save the stronger currents at Nusa Penida for when you feel confident, and wear a flotation vest if you are at all unsure.
What is the best time of year to go?
The dry season from about April to October gives the calmest seas and clearest water. July to September is the busiest stretch, so book early. Wet-season snorkelling is possible but conditions vary, so stay flexible.
How much should I budget for a snorkelling day?
A fast boat ticket from Sanur starts from about S$8 to S$13 one way, a guided snorkelling safari from around S$31, and a full day tour or cruise from roughly S$47 to S$116 depending on what is included. Add tips, lunch and sunscreen to your total.
Do Singapore citizens need a visa for Bali?
Singapore passport holders can enter Indonesia visa-free for up to 30 days under the ASEAN exemption. Other nationalities may need an e-visa or visa on arrival. Check our visa requirements pages and the official source before you travel, since rules can change.
Can I snorkel if I am not a strong swimmer?
Many people do. Tell your guide, wear a flotation vest, choose calm sites such as Sanur or Lembongan, and stay close to the boat. Never go out alone in open water.
Will I definitely see manta rays at Nusa Penida?
Not guaranteed. Mantas are wild animals, and sightings depend on tides, season and luck. Plan for a great day regardless and treat any manta encounter as a bonus.
What should I bring on a snorkelling trip?
Bring reef-safe sunscreen, a rash vest, a towel, a hat, a dry bag, a waterproof phone pouch, water and a little cash for tips. Most operators provide a mask, snorkel and fins, but check the inclusions.
Is Bali snorkelling family friendly?
It can be, especially at sheltered spots. Children should wear vests, stay within arm's reach of an adult and take regular breaks. Choose operators who list child-appropriate equipment and shorter outings.
