Hang Toi

Cave in Phong Nha-Ke Bang National Park

Incorporating an above-water zipline, followed by a swim into the cave and then exploration of a pitch-black passageway of oozing mud, it's little wonder Hang Toi is the cave experience you've probably already heard about from other travellers. Upon exiting the cave, a leisurely kayak paddle heads to a jetty where there are more into-the-water zipline thrills to be had.

The Dark Cave can be visited independently or on tours booked with local accommodation.
