Eden Sike Cave is a small cave in Mallerstang in the Eden valley in Cumbria, England 400 metres (440 yd) north of Hell Gill. The entrance is 391 metres (428 yd) north west of an obvious resurgence in a small shakehole. This drops into a passage where a wet crawl leads downstream towards the resurgence, and a roomier passage going upstream. The upstream passage soon deteriorates into more awkward going which eventually passes a small but awkward climb into an inlet passage up to the right.
