Tu Lan

Hang Ton, first found in 1992 and explored more in depth in 2012, appears first on the horizon on a trek to this intricate cave system. Its dry entrance provides an outstanding view of the valley below, and promises many more adventures inside. A ladder inside leads to the floor of the cave, and from there the journey truly begins, where one must swim through the cave to reach the exit on the other side.
Of course, locals have been visiting some these caves for thousands of years as well.

The river caves in this system such as Ken Cave and Tu Lan Cave are very young, only about 3 million years old. The higher, dry caves (dry Tu Lan and Ton Cave) are much older, and date around 5 million years old.
The stalactites and stalagmites are enormous and breathtaking. One of the caves in the Tu Lan cave system, Ken Cave, even had it’s beautiful formations featured recently in National Geographic by world renowned photographer Carsten Peter.

Oxalis is very proud to have been involved directly in arranging a number of aspects of the production including assistance with the location. Quite a number of our porters from the village of Tan Hoa, plus some of our guides were even hired by the team to support the cast and crew during the shooting days.
Also, recently a couple of other caves including Hung Ton and Rat Cave, were used in the Vietnamese film “The Immortal” By Director Victor Vu. This was a big hit in Vietnam and followed the journey of a man who mysteriously spent hundreds of years living in Tu Lan before being drawn out by love, though this is more a thriller than a love story!
