Ko Phi Phi Le, 6. 6 km2 in area, is the second largest island of the archipelago, the largest being Ko Phi Phi Don. The island consists of a ring of steep limestone hills surrounding two shallow bays, Maya Bay and Loh Samah. During low tide, Maya Bay cannot be accessed directly from the sea via boat, due to shallow waters and coral. Boats must anchor at the deeper Loh Samah, requiring people to walk through a short section of rocks and jungle to reach Maya Bay itself. There is also one large shallow fjord-like inlet called Pi Ley with a small coral reef at the entrance. Maya Bay harbors bioluminescent plankton.
