According to locals, the cave is about 5-6km long and has two entrances

An entrance to Tham Phay (also known as Lua or Fire) Cave

It is very difficult to walk inside the cave as some parts are just 1m high

Water resources in Tham Phay Cave create a huge reservoir

There are more uncanny stalactites running along the two sides and on the ceiling

A carpet of plants outside the entrance

The highest part inside the cave is around 20m
