Phra Nang Cave, also known as Diamond Cave, on the east side of the peninsula, to the north of Rai Leh East, is an interesting place to explore and one of the few strictly sight-seeing destinations at Rai Leh. A nominal entrance fee pays for a short walk along the lit boardwalk through formations that glitter as if they were full of diamonds. Though not breathtakingly large (and thus easily viewed in about fifteen minutes) it is quite beautiful. The cave is a common stop for day trips from Phuket and Ao Nang. Admission is B40.
