Tu Lan Cave System is comprised of over 10 caves in all, some of which were originally discovered and explored in 1992, and some of which were just found in the past couple years. 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.


This tour is to give you a taste of Tu Lan, see the immense formations of Hang Chuot (Rat Cave) before trekking to impressive Hung Ton Cave and To Mo Valley.
