The Hang Tien Endeavor is a great combination of jungle trekking, caving, and outdoor camping adventure. As the largest cave in Tu Lan cave system, Hang Tien is famed for its enormous size and spectacular formations.

Our guide will bring you into depths of Vietnamese jungle where the lost world of ancient rock configurations can be found dripping from the ceilings, and spending a night under a net of a thousand stars is truly a unique chance to enjoy the real wilderness of this country.

With formations rising up like a layer cake of rimstone pools and lush ferns, Hang Tien, or “Fairy Cave”, is truly a unique specimen. Highlights of the tour include gour pools, swimming in lakes within a cave, a natural lagoon pool, and cave side waterfalls.
