About Dark and Bright Cave

The Dark and Bright Cave is a highlight of the Lan Ha route. A local oarswoman rows you through the longer "dark" tunnel, the only light a torch beam on the water, before you emerge into the "bright" passage and a hidden lagoon ringed by jungle.

It is calm, atmospheric and entirely car-free — one of the most memorable half-hours on any cruise here.
