Change over to the west side and it is as you are at a totally different location. Here, huge granite boulders stacked on top of one another create cavern and swim-through. Fishlife there is the most varied of Thailand; Reef sharks, turtles and rays make regular appearances. Huge gorgonians, dendronephthyas, shelter hips of invertebrates and sea fans and bright yellow tube corals add to the orgy of color.

The five islands are closely grouped together; the main islands larger than any of the Similans and covered in verdant rainforest. A small Sea Gypsy community lives on the east coast.
