After much of the day scrambling deep in the cave system, we reach the mouth of cave. This means we are back to the real world.
Photo taken in the Clearwater cave system in Gunung Mulu National Park (Borneo)
The Clearwater System is believed to be the largest interconnected cave system in the world by volume and the 9th longest cave in the world at 189 Km (as of 2011).
