Diamond Cave, also known as Phra Nang Nai Cave, is a must-visit spot at Railay Beach in Krabi, Thailand. This natural limestone cave features impressive stalagmite and stalactite formations, a cool interior offering respite from the heat, and the chance to spot some bats. The main cavern even has a pool that sparkles in the rainy season, giving the cave its name. Just a short walk from Railay East Beach, it's a cool little adventure to add to your list when exploring the area.
