Whether you’re a first-time visitor or a seasoned traveller returning for more, snorkeling, island hopping, and scuba diving around Phi Phi offer some of the most thrilling marine experiences in Southeast Asia. The waters here are warm, crystal clear, and teeming with life — from vibrant coral gardens to reef sharks gliding silently beneath long-tail boats. Here’s how to make the most of every moment on and under the water.
Choose the Right Base for Your Adventures
Where you stay makes a significant difference in how easily you can access the best water activities. Staying directly on the islands — rather than day-tripping from Phuket or Krabi — gives you first access to sites before the crowds arrive.
SAii Phi Phi Island Village is one of the most well-positioned properties for this. Set along a quiet stretch of Loh Dalum Bay, the resort offers direct beach access and can connect guests with reputable local operators for guided snorkelling tours, island-hopping excursions, and dive trips. Starting your morning from the resort means you’re already at the water’s edge — no ferry transfers needed.
Snorkelling: Know Where to Go
The waters around Phi Phi are dotted with excellent snorkelling spots, but not all are created equal. The most rewarding sites include:
-
- Hin Klang — a submerged pinnacle between Phi Phi Don and Phi Phi Leh, ideal for intermediate snorkellers looking for an immersive experience among schooling fish and soft corals.
- Maya Bay Reef — the lagoon itself may be famous, but the reef just outside is where the real colour lives. Arrive early or late in the day to avoid boat traffic.
- Ao Nui — a sheltered cove on Phi Phi Leh with calm, shallow water perfect for beginners and families.
Bring reef-safe sunscreen, a quality mask and snorkel (or rent from a trusted operator), and always snorkel with a buddy.
Island Hopping: Build the Right Itinerary
A classic island-hopping day around Phi Phi typically takes in three to five stops and can be done by chartered longtail boat or joined tour. The key is balancing the iconic landmarks with the quieter, lesser-visited spots.
A well-rounded route might include:
- Viking Cave on Phi Phi Leh, where swiftlets build nests high on the cliff walls
- Monkey Beach for a brief stop to observe (but not feed) the local macaques
- Bamboo Island (Koh Mai Phai) for some of the whitest sand and clearest water in the area
- Pileh Lagoon, a stunning emerald-green lagoon enclosed by towering limestone
Book your boat early in the day. Afternoons can get choppy, and popular spots like Pileh fill up quickly with tour groups from the mainland.
Scuba Diving: From Beginner Dives to Advanced Sites
Phi Phi’s diving ranges from gentle introductory dives to exhilarating drift dives and shark-spotting sites. The visibility here regularly reaches 20–30 metres in the dry season (November to April), making it one of Thailand’s best diving destinations.
Key dive sites to know:
Hin Daeng and Hin Muang (accessible as a day trip) — for advanced divers, these twin seamounts are considered among the best dives in all of Thailand, with manta rays and whale sharks occasionally spotted.
- King Cruiser Wreck — a sunken ferry that now teems with marine life, suitable for divers with Open Water certification.
- Anemone Reef — a soft coral-draped pinnacle bursting with clownfish, moray eels, and lionfish.
If you’re a beginner, many local dive shops offer PADI Discover Scuba Diving experiences that require no prior certification. A single day is enough to complete a confined water session and do two open-water dives.
Practical Tips
- Best season: November to April offers calmer seas and better visibility. May to October is monsoon season — diving is still possible but conditions vary.
- Book ahead: During peak season (December–February), reputable dive operators and island-hopping boats fill up fast. Reserve at least a day in advance.
- Respect marine life: Do not touch coral, chase marine animals, or collect shells. Phi Phi’s reefs have recovered significantly in recent years and responsible tourism keeps it that way.
- Sun protection: The tropical sun is intense on the water. Wear a rash guard, apply reef-safe sunscreen, and stay hydrated throughout the day.
- Cash on hand: Many longtail boat operators and smaller dive shops on the islands are cash-only. ATMs are available on Phi Phi Don but can run out during busy periods.
- Start early: The best light for underwater photography, the calmest seas, and the thinnest crowds all happen before 9 a.m. Make sure to set your alarm.
