Experience the World’s Largest Cave with a team of safety experts, professional guides and porters on this world-class tour of Hang Son Doong. This caving adventure is suitable for budding explorers, trekkers and photographers with a thirst for the ultimate adventure!
Explore the fascinating secrets of the newly discovered Son Doong Cave on this once-in-lifetime opportunity offered by Oxalis Adventure Tours. In a small team of up to eight guests, you’ll trek deep in the remote jungle of Phong Nha Ke Bang National Park, cross stunning river valleys, meet the friendly Bru VanKieu minority people of Doong Village, and bear witness to incredible cave formations unlike anywhere else in the world.
More like a mini-expedition, a team of more than 16 porters, safety experts and guides will accompany you on your six-day adventure, with two nights camping in magnificent Hang En and three nights in the World’s largest cave, Hang Son Doong.
Safety is absolutely paramount on all trips operated by Oxalis Adventure Tours and hence two of the very best caving experts from the UK will accompany each tour of Son Doong Cave. Ropes, safety harnesses, lights and helmets are necessary to enter Son Doong and these are all provided from European manufacturers such as Petzl and Mammut.
Camping gear is provided and will be setup for guests upon arrival at each campsite. A team of porters will carry all gear and assist you with your own gear to ensure you can comfortably maneuver your way through the cave on each day.
We are committed to cave conservation, and hope to preserve the beauty of Son Doong Cave for future visitors and have hence imposed a number of rules to ensure no damage is caused to any cave formations or the general cave ecosystem. Composting toilets are used at each campsite and all rubbish and waste removed at the completion of each tour of Son Doong.
