Eastwater Cavern is also known as Eastwater Swallet, and that's why it is listed here. The cave is a swallow hole, which means surface water flows into the cave and enters the karst. However, the surface water flows only during wet periods and so the canal of the river is dry most of the time. This cave is dangerous and not accessible to the public. But the swallow hole and the cave entrance is very impressive and well worth a visit. The swallow hole is located close to the road and reached after a short walk.

The cave behind the swallow hole is of impressive size. The total length is 2.8 km and it reaches a depth of 160 m. Various drops make it very demanding and dangerous, even for cavers. One of the shafts called Primrose Pot is 58 m deep and is one of the deepest vertical pitches on the Mendips.
