It is a 30-minute hike into the rainforest to this huge overhanging cave and waterfall. The waterfall is 150 feet high and the cave more than 900 feet across. A large colony of bats live in the cave and there is access behind the waterfall that leads to the Kupwuriso cannons, relics from the WWII era. Indeed this is where the name Pahn Takai, which means “underneath the rock”, is derived from.
