Diving & Snorkelling on Koh Phi Phi
Andaman limestone, gentle sharks, turtles and a wreck

Underwater, Koh Phi Phi is sheer limestone pinnacles where fish gather, turtles drift past, and shy, harmless blacktip sharks patrol the shallows. Here's the honest version: the top dive sites for certified divers, the best snorkelling for non-divers, island-hopping boat tours, the clearest Andaman season, and how to choose a dive shop on safety — not just on price.

Why dive Phi Phi

The magic here is as much under the water as above it

Koh Phi Phi (เกาะพีพี) is an Andaman island group in Krabi province, out in the sea between Phuket and Krabi/Ao Nang. There are two main islands: Ko Phi Phi Don (the inhabited one, with Tonsai village and the pier) and Ko Phi Phi Leh (uninhabited, day-trip only, home to Maya Bay). What the world knows Phi Phi for isn't only the sheer limestone cliffs above the waterline — it's the world below: submerged limestone pinnacles where fish school thickly, turtles, small harmless reef sharks, and the clear water of the Andaman side.

The good thing about Phi Phi is that it has something for both divers and non-divers. Certified divers can head out to pinnacles like Bida Nok and Bida Nai and the King Cruiser wreck, while anyone who has never dived can snorkel over coral and fish at Bamboo Island or Monkey Beach. We'll say it plainly from the start: Phi Phi is gorgeous, but it's also busy and boat-heavy, especially mid-morning when the day-trip crowd arrives all at once. If you want clear water and fewer people, a sunrise trip is the answer — worth knowing before you come, so you set your expectations right.

The short version, before the detail: the headline dive sites are Bida Nok and Bida Nai · Shark Point (Hin Bida) for blacktip sharks · the King Cruiser wreck (between Phi Phi and Phuket) and Anemone Reef · snorkel at Bamboo Island, Monkey Beach and Loh Samah · the best season is Nov–Apr (clearest water) · sharks and any wildlife sighting come down to luck — never guaranteed — and the single most important thing is to pick a dive shop that's safe and well-reviewed, not the cheapest one.
Pick what suits you

Dive deep, snorkel, or learn from scratch

Around Koh Phi Phi there are snorkelling tours for non-divers, fun dives for the certified, and courses if you want to qualify. Prices are given as ranges because they shift with the year, season and shop.

Island-hopping snorkel tour
No deep dive · suits everyone

The easiest option for non-divers. A boat tour (speedboat or longtail) links several spots in one trip — Bamboo Island, Monkey Beach, the Maya Bay area, Loh Samah — over a half-day or full day. Snorkel gear is provided and some trips include lunch. It costs about ฿800–2,500 depending on the boat type and stops. A sunrise trip arrives ahead of the fleet, so the water is clearer and there are far fewer people.

Time: Half-day–full day · no experience needed
Price: About ฿800–2,500 (park fees extra)
Best for: Everyone, families and kids included

Fun dives (already certified)
Go deep · on a dive shop's boat

If you're already certified, just book fun dives on a dive shop's boat. These usually run as two-dive trips out to pinnacles like the Bida rocks and Shark Point, or further afield to the King Cruiser wreck. A trip costs around ฿2,500–4,500 (cheaper in a multi-dive package, and usually discounted if you bring your own full set of gear). Bring your certification card and logbook. Which sites you can do depends on your level and the sea conditions that day.

Format: Two dives per trip · on a shop's boat
Price: About ฿2,500–4,500/trip (packages cost less)
Bring: Certification card + logbook
🤿3
Open Water course
Your first certification · PADI or SSI

Want an internationally recognised dive certification you can use anywhere? The Open Water course takes about 3–4 days, split between theory, skills in shallow water, and several dives in the open sea. On Phi Phi it costs around ฿13,000–17,000, usually covering tuition, gear and the exam (more than the budget learn-to-dive islands on the Gulf side, because this isn't a cut-price training market). Ask clearly what is and isn't included, and choose a shop that puts safety first.

Time: About 3–4 days · theory + shallow + open water
Price: About ฿13,000–17,000 (usually gear + certification)
You get: A dive certification valid worldwide

Discover Scuba (a first try-dive)
Never dived · try before you commit

Never dived and want to find out if you like it? Discover Scuba Diving takes just half a day to a day: an instructor teaches the basics in shallow water, then takes you on a real, shallow sea dive under close supervision. You don't get a certification, but you get the genuine experience. It costs about ฿3,000–4,500, and if you enjoy it, many shops will credit it towards a full Open Water course. Tell your instructor honestly about any health issues before you get in.

Time: Half a day–1 day · no experience needed
Price: About ฿3,000–4,500 (ask what's included)
Best for: Trying it before the full course
How to book: dive courses and fun dives are best booked directly with a dive shop on the island, or in Phuket/Ao Nang — you can talk through the details, see the gear and negotiate. Snorkelling boat tours and inter-island ferries, though, can be booked ahead on Klook — see the foot of this page.
Top dive sites

What's down there to see

There are several dive sites around Koh Phi Phi; these are the ones people talk about most — some suited to certified beginners, some you'll need experience or an Advanced certification for first.

🪨 Bida Nok
The standout site · south of Phi Phi Leh

A limestone pinnacle rising from the sea south of Phi Phi Leh, which many rate as the best dive site at Phi Phi. Its walls drop away sheer, drawing thick schools of fish, with a chance of turtles, leopard sharks resting on the sand, and sometimes blacktip sharks. Best for certified divers with a bit of experience.

Level: Certified beginners and up · Highlight: Turtles + leopard sharks + fish
🪸 Bida Nai
Paired with Bida Nok · walls and small caverns

A pinnacle paired with Bida Nok and close by, so dive trips often do both in a day. The highlights are its walls, soft coral, small swim-through caverns and fish schools, with a chance of turtles and blacktip sharks too. The current is gentle to moderate, and visibility is usually good in the dry season. Instructors like it for both training and fun dives.

Level: Certified beginner–general · Highlight: Walls + soft coral
🦈 Shark Point (Hin Bida)
A submerged reef · blacktip sharks (harmless)

A submerged reef known for blacktip reef sharks — shy and harmless to people — with frequent turtles, bright soft coral and sea anemones. (Don't confuse it with the other Shark Point near Phuket; the area has duplicate names.) It's an open-water site, best for certified divers with some experience. Watch the wildlife from a distance and never chase it.

Level: Certified/experienced · Highlight: Blacktip sharks + turtles
🚢 King Cruiser Wreck
Between Phi Phi and Phuket · for experienced divers

A large car ferry that sank in 1997, lying in open water between Koh Phi Phi and Phuket. It's now an artificial reef swarming with fish, and one of the most popular wreck dives in the Andaman. It's a deep site and the current can be strong at times, so it's best for divers with an Advanced certification or solid experience. Trips often run from Phuket or Ao Nang rather than Phi Phi itself.

Level: Advanced/experienced · Highlight: The wreck + fish
🌺 Anemone Reef
A submerged pinnacle · anemones + clownfish

A submerged pinnacle near the King Cruiser, its top carpeted in sea anemones and full of clownfish and other reef fish, with a chance of larger species passing through to feed. It's an open-water site where the current can run, so it suits experienced divers, and it's often paired with the King Cruiser wreck on one trip.

Level: Certified/experienced · Highlight: Anemones + clownfish
🐠 Palong + around Phi Phi Leh
Shallow–moderate · good for training and fun dives

The reef around Palong Bay and the shallower spots near Phi Phi Leh — shallow to moderate, gentle current, plenty of coral and fish. They're where instructors like to take students for their first dives, and they're snorkellable too, with a chance of small blacktip sharks in places. Good for beginners and anyone after an easy dive.

Level: Beginner/course dives · Snorkellable: In parts
⚠️ On sharks, to be clear: the sharks you'll see around Phi Phi are blacktip reef sharks and leopard sharks — shy and harmless to people, not the predators of the movies. They tend to swim away rather than towards you. A sighting comes down to luck and season, and nobody can guarantee it. Some people see one on their first dive; others dive a whole trip and never do. The rule is to watch from a distance, never chase, touch or feed them — and if you don't see one, there's still plenty else to see.
Snorkelling for non-divers

No deep dive needed to see reef and fish

No certification, no course — just a mask and snorkel and you can see Phi Phi's underwater world. These are the best snorkelling spots.

🎋 Bamboo Island (Ko Mai Phai)
North of Phi Phi Don · white sand + shallow reef

A small island north of Phi Phi Don and the most popular snorkelling spot: fine white sand and shallow reef around it where you can see fish easily right off the water's edge. It's part of a national park, so there's an entry fee on arrival, and some years it closes for periods to let the reef recover. It gets busy by mid-morning — a sunrise trip means clearer water and fewer people.

Highlight: White sand + shallow reef · Note: Park fee, may close at times
🐒 Monkey Beach
Phi Phi Don · reef close to shore + monkeys

A small cove on the west side of Phi Phi Don, reached by boat, with coral and fish close to shore that make for easy snorkelling — and a troop of macaques living on the beach, as the name suggests. Don't feed or approach the monkeys; they bite and snatch things. Keep food and bags zipped away. Most island boat tours stop here.

Highlight: Reef close to shore · Watch: Monkeys — don't feed/approach
🏝️ Loh Samah + Pileh Lagoon
Phi Phi Leh · clear water in sheltered bays

Loh Samah, on the back side of Phi Phi Leh near Maya Bay, has clear water and lots of fish and is a popular snorkelling spot. Pileh Lagoon is an emerald-green lagoon ringed by cliffs, beautiful for a swim and gentle snorkel. Both sit in sheltered bays, so the water is calmer than the open sea outside.

Highlight: Clear water + a stunning lagoon · Best for: Snorkelling/swimming
⛵ Mosquito Island + Nui Bay
Further out · quieter, clearer water

Mosquito Island (Ko Yung), a small island to the north, has shallow reef and fewer people than Bamboo Island, while Nui Bay, on Phi Phi Don, is a small, quiet cove with clear water for calm snorkelling. Both are on some island boat-tour routes — if you want to escape the crowds, ask whether your tour stops at these.

Highlight: Quiet + clear water · Best for: Avoiding the boat fleet

Maya Bay — know before you go

The most famous beach has rules you need to understand

Maya Bay on Ko Phi Phi Leh is the image of Phi Phi, but after its reefs and marine life took a heavy battering, it was completely reorganised — you can visit, but you have to know the rules.

🚫 Usually no swimming in the bay
Enter via the back bay + boardwalk

Maya Bay was closed for recovery from 2018 to 2022, then reopened with strict rules. These days you usually can't swim in the bay itself, and boats can't anchor in it. Visitors come in via a pontoon in the back bay and walk in along a boardwalk, with limited numbers and timed entry. Check the latest rules before you book.

Note: Usually no swimming in the bay · enter via the back
📅 Periodic seasonal closures
Some years ~Aug–Sep · always check first

As well as the daily rules, Maya Bay has periodic seasonal closures — some years it shuts around August–September to let nature recover — and no overnight stays are allowed on Phi Phi Leh. The dates and rules change every year, so before you buy a tour that advertises Maya Bay, ask clearly whether the bay is actually open during your dates.

Note: May close at times · no overnight stays on Phi Phi Leh

Choosing a dive shop — straight talk

Don't choose on lowest price alone

There are plenty of dive shops around Phi Phi, Phuket and Ao Nang, and many are good, but the very cheapest can mean big groups or worn gear. This is a safety decision — choosing well is worth more than saving a few hundred baht.

🛡️ Check the safety record and real reviews
Read reviews from several sources, not just the shop's own site. Look for comments about safety, how attentive the instructors are, and care — not only "fun" or "cheap". A shop that's been running a long time with consistent reviews is usually safer to trust.
👥 Ask about group size and instructor ratio
The fewer students per instructor, the better — especially on a beginner course. Ask directly how many people there are per instructor. A small group means closer supervision and a safer dive. If the shop is evasive, or the groups are very large, look elsewhere.
🤿 Ask to see the condition of the gear
Good dive gear should look well looked-after and regularly serviced. Drop by the shop and see it in person before you sign up, and ask how often the equipment is serviced. Gear that looks very old or damaged is a warning sign — seeing it for yourself tells you a lot.
💬 Talk before you pay, and trust your gut
A good shop answers your questions happily and won't pressure you to pay quickly. Ask what certifications the instructors hold and what their safety procedures and emergency plan are. If you feel rushed, the answers are vague, or you're just not comfortable, walk on — there are plenty more shops here.
⚠️ Why we don't name a specific shop: there are many good dive shops around Phi Phi, Phuket and Ao Nang, but shops open and close, change owners, and quality varies over time. So we won't name a shop whose current status we can't verify — we'd rather you choose using the criteria above yourself than trust one name. That approach works whatever year you visit.
Season, visibility and underwater etiquette

When to go and how to dive so the sea stays

Koh Phi Phi is on the Andaman side, so its season is the opposite of the Gulf islands — some months have much clearer water and calmer seas — and whenever you go, reef etiquette is something everyone needs to know.

☀️ The best window: Nov–Apr
Calm seas, clear water, best visibility

The Andaman is best from around November to April — calm seas, clear water, the best underwater visibility, and all the tours running. It's the easiest time to reach far sites like the King Cruiser. March and April are very hot, and it's also the busiest stretch, so book tours and ferries ahead.

Best: Nov–Apr · Clear water: The year's best visibility
🌧️ The rougher window: May–Oct
Southwest monsoon · some days still diveable

May to October is the Andaman monsoon — rougher seas and more rain. Some ferry crossings can be cancelled and underwater visibility is more variable. But on calm days you can still dive, with fewer people, and more sheltered sites often still run even when the open sea is up. If you come now, allow flexible days and check conditions with your shop.

Monsoon: May–Oct · Diving: Some days still run, allow for cancelled ferries
🪸 Don't touch or stand on coral
Coral is alive, and very slow to recover

The first rule of every dive: don't touch, hold or stand on the coral. Coral is a living thing — slow-growing and fragile, and even a touch or a fin kick can damage it. Phi Phi's reefs have taken heavy use, so control your buoyancy, keep your gear from dangling and dragging, and don't take anything from the sea. Just look.

Hard rule: No hands, no fin kicks, never stand on coral
🧴 Reef-safe sunscreen
Don't chase or feed wildlife · take your rubbish

Choose a reef-safe sunscreen that avoids chemicals known to harm coral, or wear a long-sleeve rash top instead. Don't feed the fish, don't chase or crowd turtles and sharks for a photo, and take every piece of rubbish back out with you. Good diving leaves as little trace as possible, so the next generation sees the same sea you did.

Do: Reef-safe sunscreen/rash top, pack rubbish out · Don't: Feed/chase wildlife

So, is Phi Phi for you?

Honestly — worth it if you love the sea, but brace for crowds

If you want to dive or snorkel in clear Andaman water, see sheer limestone both above and below the surface, and stand a chance of turtles and harmless sharks — Phi Phi is one of the most beautiful places in Thailand for exactly that. There's something for divers and non-divers alike, the dive sites are varied, and it's easy to reach from Phuket, Krabi or Koh Lanta (in high season).

But here's the truth: Phi Phi is very busy and very boat-heavy, especially mid-morning when the day-trips arrive together. Popular bays can be crowded and loud, and some reefs have taken heavy use. The way to enjoy it is to take a sunrise trip that beats the boat fleet, choose a smaller-boat tour with fewer people, and pick the quieter outer spots. Set your expectations there and you'll enjoy it far more.

⚠️ Getting around the islands, to be clear: Koh Phi Phi has no cars and no roads for vehicles. You get around on foot (Tonsai village is a maze of walkable little lanes, all within reach of each other) and reach the far spots by longtail or speedboat. There are no taxis and no scooters to rent for getting anywhere. For getting on and off tour boats, watch for slippery wet decks and swell, wear the life jacket the boat provides, and listen to the safety briefing before every trip.
Frequently asked

FAQ · before you dive Koh Phi Phi

What are the best dive sites around Koh Phi Phi?
The most talked-about dive sites around Koh Phi Phi are Bida Nok and Bida Nai, two limestone pinnacles south of Phi Phi Leh where you've a chance of turtles, leopard sharks resting on the sand, and big schools of fish. Shark Point (Hin Bida) is known for harmless blacktip reef sharks. Certified divers after something different head to the King Cruiser wreck, a sunken ferry between Phi Phi and Phuket, and Anemone Reef, a pinnacle carpeted in sea anemones and clownfish. Which site suits you depends on your certification level and experience, so always talk it through with a dive shop before you book.
Can you see sharks diving at Koh Phi Phi, and is it safe?
Yes, you can — especially small blacktip reef sharks at Shark Point (Hin Bida) and sometimes in the shallow bays around the islands, and leopard sharks (also called zebra sharks) resting on the sand near the Bida pinnacles. Both are shy and harmless to people; they're not the predators of the movies and tend to swim away from divers. The rule is to watch from a distance, never chase, touch or feed them, for everyone's safety, theirs included. Seeing a shark comes down to luck and season, and nobody can guarantee it, so treat it as a bonus if it happens.
Where's the best snorkelling for non-divers at Koh Phi Phi?
Koh Phi Phi has plenty of good snorkelling for non-divers. Bamboo Island (Ko Mai Phai) has white sand and shallow reef close to shore and is the most popular spot. Monkey Beach and Loh Samah, on the back side of Phi Phi Leh, have clear water and lots of fish, and you can snorkel in parts of the Maya Bay area at designated spots (you usually can't swim in the bay itself). The easiest option is a half-day or full-day snorkelling boat tour that links several spots in one trip, with gear provided. Bring a mask that fits and reef-safe sunscreen, and never stand on or touch the coral.
Is Bamboo Island worth it?
It's worth it if you love white sand and clear-water snorkelling. Bamboo Island (Ko Mai Phai) is a small island north of Phi Phi Don with fine white sand and shallow reef around it where you can see fish easily without diving deep. Most boat tours stop here. It's part of a national park, so there's an entry fee on arrival, and some years it closes for periods to let the reef recover. The downside is that it gets busy and the beach crowds by mid-morning, so a sunrise tour that arrives before the fleet of boats is well worth it. Always check the latest rules and any closures before booking.
What's the best season for diving at Koh Phi Phi?
Koh Phi Phi is on the Andaman side, so the best season for diving and snorkelling is roughly November to April: calm seas, clear water, the best visibility, and all the tours running. March and April are very hot. The monsoon runs roughly May to October, with rougher seas and more rain; some boat crossings can be cancelled and underwater visibility is more variable, but on calm days you can still dive and there are fewer people. If you come in the monsoon, allow flexible days and check conditions with your dive shop, as more sheltered sites often still run even when the open sea is rough.
