About Luon Cave

Luon Cave is less a cave than a tunnel: at low tide you glide beneath a curved rock arch and emerge inside a calm, almost circular lagoon enclosed by towering green walls.

It is one of the quietest corners of the central bay, home to langurs in the cliffs and a mirror-still surface that makes paddling here feel wonderfully remote.
