Huge natural cave in the Niah National Park (Borneo).

The wooden pathway gives an idea of the scale. This chamber is about 40m high and 150m wide. The small white point in the back is sunlight coming from a enormous sinkhole in the roof of the cave, 500m inside the cave.

This is the 200m wide chamber at the entrance of the Great Cave. It is very large with huge chambers, up to 75m high, and a network of tunnels covering 10 hectares.
