There are over 850 steps to ascend to the entrance from where a steeply descending route, spiralling down between boulders, leads to a large chamber 50 m wide and 15 m high, with much guano and many bats. Below this chamber the cave follows a very large, straight passage along the strike towards the south. The passage is up to 30 m wide by 20 m high and in parts has a smooth earth floor for a straight 100 m. Despite being a show cave the going is quite difficult in places with very subdued lighting so boots and your own light are recommended. The tour ends at a lake but the cave continues for another 100 m to a mud choke.
