Why go
For the inside of the limestone that you otherwise only see from the beach: formations of stalactites and stalagmites, lit inside, so you need no torch.
What you will find
Tham Phra Nang Nai, known as Diamond Cave, lies within the national park, and tickets are sold at a booth at the entrance. A walkway loops through the cave, lit by electric lights.
It is not the shrine of the sea princess: that is Phra Nang Cave, on Phra Nang Beach.
Getting there
Railay is reached by boat only. The cave is above Railay East, on the path towards Tonsai, and a short walk from either Railay East or Railay West.
Before you go
Entry is paid at the booth. The prices quoted online date from 2020, and one more recent visitor found the price negotiable and got no receipt, so check the amount on the spot and ask for a ticket.
The walkway is not accessible by wheelchair.
