The Phi Phi archipelago rises from the Andaman Sea as a cluster of six limestone towers, their cliffs plunging into water so clear that visibility routinely exceeds twenty meters.
Designated a marine national park in 1983, the islands shelter over 200 coral species and serve as feeding grounds for blacktip reef sharks, leopard sharks, and seasonal manta rays. Maya Bay — closed for ecological recovery between 2018 and 2022 — now operates under strict daily visitor quotas, its crescent beach accessible only before 10:00 and after 14:00 to protect nesting sea turtles. The 400-baht conservation fee, collected at park checkpoints, funds reef restoration projects and patrol vessels that enforce no-anchor zones around fragile staghorn colonies.
A phi phi snorkeling tour from krabi departs the Ao Nang pier complex at 79 Moo 5, where speedboats and longtail vessels queue under the shade of casuarina trees. Most operators follow a counter-clockwise route: north to Bamboo Island's shallow sandbar, east to Phi Phi Leh's Viking Cave, then south into Pileh Lagoon, a jade-green fjord enclosed by 100-meter karst walls. The lagoon floor drops to fifteen meters, its gradient reef hosting parrotfish, damselfish, and moray eels that hunt from crevices in the coral bommies. Early morning departures reach sites before the midday swell stirs sediment, offering the season's best visibility from November through April when monsoon winds subside.
Monkey Beach, on Phi Phi Don's western shore, anchors most itineraries as a final stop. Long-tailed macaques descend from the canopy to forage tidal pools at low water, their troop numbering roughly eighty individuals. Park rangers prohibit feeding, a policy enforced since 2019 after human food altered the macaques' foraging patterns and dental health. The beach itself curves along a fringing reef where elkhorn coral and brain coral form a breakwater visible from the surface. Guides brief snorkelers on current direction and exit points before entering the water, a protocol standardized after the park authority mandated safety briefings in 2021. The phi phi snorkeling tour from krabi ticket includes mask, fins, and buoyancy vest, distributed aboard the vessel during the 45-minute crossing from Krabi's coastline.
