These are two large boulder formations located at the cape on the east side of Chalok Baan Kao Bay.

Hin Taa Toh is a group of boulders creating an almost human-like shape and resembles a male in a sitting position. Hin Yaai Mae is the female. Both are believed to be ‘spirit rocks’ and are treated with respect by the local population and are famous Koh Tao landmarks. A photo of Hin Taa Toh is often seen in local people’s houses, where it is revered and worshipped.
