Tham Phra Nang Nai

Railay


A wooden boardwalk leads through a series of illuminated caverns full of beautiful limestone formations (and squeaking bats) but, with shifting rain patterns, the water is now gone and with it the luminescent effects that won it the 'diamond' moniker. It's pricey for what you see. Follow signs north off Walking St (five minutes' walk).
