This skills-based caving adventure provides a highly informative insight into this unique caving region, home to the most spectacular caves and jungle of Vietnam!

On this tough jungle and cave trek there is plenty to keep your heart racing with some dark cave abseiling, bouldering, climbing and a lot of swimming through the caves. Our secluded jungle campsites are spectacular and mostly different from those visited on our shorter treks in the same region.
