Home to the world’s largest caves,
central Vietnam’s Phong Nha is redefining
adventure travel in Asia

Oxalis Adventure is the leading adventure tour operator in Vietnam

We pioneered life-changing caving and jungle experiences in UNESCO-recognized Phong Nha-Ke Bang National Park and we are the gateway to Son Doong, the largest cave on the planet. But Son Doong is only the beginning – 70% of the jungle remains unexplored.

We’ve discovered and we visit more caves than anyone else

Some are big enough to fit skyscrapers, lending themselves to underground campsites unlike anywhere else in the world. Others house swimmable rivers that burrow beneath the ground. Every adventure is possible, from one-day adventures to four-day expeditions.

Community involvement and safety are paramount

Oxalis Adventure is 100% locally owned and we provide employment for hundreds of tour guides and porters in one of Vietnam’s poorest provinces. But we work closely with caving experts from the British Cave Research Association to ensure that we meet international standards of safety and safeguard the integrity of the caves.

Team building with a difference
