The show cave consists of a dry gallery connecting three large chambers, the first of which contains the Witch of Wookey formation. There are various high level passages leading off from these chambers, with two small exits above the tourist entrance. The River Axe is formed by the water entering the cave systems and flows through the third and first chambers, from which it flows to the resurgence, through two sumps and long, where it leaves the cave and enters the open air.
