Phi Phi Snorkeling Tour From Ao.nang

The Hat Noppharat Thara-Mu Ko Phi Phi National Park protects 390 square kilometres of limestone karst and coral shelf between Krabi's mainland coast and the open Andaman. Established in 1983, the marine reserve encompasses six principal islands, two of which—Phi Phi Don and Phi Phi Leh—anchor most visitor itineraries.

Phi Phi Leh's Maya Bay, closed to boats between 2018 and 2022 to allow reef regeneration, reopened with a 300-visitor hourly cap and a permanent swimming ban within the cove itself. The measure has stabilised blacktip reef shark populations and restored seagrass meadows that had disappeared under decades of anchor drag and sunscreen runoff.

Departures from Ao Nang's long-tail pier follow a westward arc across Phang Nga Bay's shallow shelf before crossing open water to the islands. Speedboat operators typically bundle Phi Phi Leh's Pileh Lagoon, Viking Cave, and Loh Samah Bay with stops at Bamboo Island's white-sand spit and Phi Phi Don's Tonsai village. Longtail routes cover fewer sites but allow slower approaches to shallow coral gardens where visibility peaks in the early morning hours. The 200-baht conservation fee, collected at Bamboo Island or Maya Bay depending on your route, funds reef-monitoring buoys and seasonal beach cleanups. All operators departing Krabi province waters are required to carry Thai Marine Department permits and limit group sizes to fifteen passengers per vessel.

Snorkeling conditions depend on monsoon patterns. November through April brings two-to-three-metre visibility and calm surface chop; May through October sees reduced clarity and periodic swells that close Pileh Lagoon entirely. Water temperature holds between twenty-eight and thirty degrees year-round. The park's northern sites—Mosquito Island and Hin Klang—see fewer visitors but require confident swimming ability; currents around the limestone pinnacles can exceed two knots during spring tides. Most phi phi snorkeling tour from ao.nang itineraries allocate three snorkeling stops and include mask, fin, and vest rental in the ticket price, with lunch served on Phi Phi Don between the second and third swim.
