The underwater terrain around the Phi Phi islands is quite rocky with rows of boulders creating channels that parallel the walls of the island. The scenery is quite dramatic even though the visibility tends to be low as the seabed is comparatively shallow in this part of the Andaman Sea.
As you swim along the base of Maya Wall, the boulders jostle for space with beautiful hard corals. These are in good condition and often mobbed by masses of glassy sweepers.
Towards the end of the dive, a shallow cave reveals an overhang where more sweepers were feeding up in the roof.
