Dark Cave
A real adventure cave, still without the lights and large tourist groups to spoil the experience. Explore this spectacular cave on a National Park tour or independently, and after kayaking across the river, enjoy swimming through the cave with your headtorch leading the way, then explore a side passage. Hang Toi is a wonderful and very accessible example of the beautiful caves that are found throughout this region.
Discovered in 2016 by a local man, this cave has the potential to be the 2nd biggest cave in the world. The first tourists experienced this cave in 2017. Green Land Tours is the only company that offers access to each of the cave's two entrances. The tours are led by the man who discovered the cave and spent 2 years exploring it.
