About Tung Trang Cave

Tung Trang is a natural water cave best explored by kayak. Timed with the tide, you slip through the low passage into a series of secluded lagoons few boats ever reach.

It is a favourite of active travellers on the Lan Ha route, rewarding a little effort with complete seclusion.
