An uninhabited islet in the Phi Phi group, dived for the multi-headed pinnacle off it. Depths are typically around 15 m, the water is generally clear and the topography varied for a site this shallow. It has been closed periodically for reef recovery, so check with your operator that it is open before you book the day.

The dive
The dive is a circuit of the pinnacle rather than a line along a reef. It is multi-headed — several rock heads standing close together — so the route weaves between them, and with depths typically around 15 m you can spend the whole dive on the structure without pushing the profile. The varied topography is the appeal here: rock, the gaps between the heads, and reef in between.
Water at the islet is generally clear, which matters on a site whose interest is shape rather than one big feature: you want to see the heads standing up around you rather than finding them one at a time. Check the status before you commit, though. The reef here has been closed periodically to let it recover, so whether it is open on the day is a question for the operator rather than the schedule.
