Mossdale Caverns (Great Whernside)


Issued: 7 November 2017

Mossdale Caverns is a seriously flood-prone cave, with passages only a few minutes into the entrance filling to the roof in flood and passages further into the cave sumping with only a small rise in river levels. Mossdale must only be considered following at least two days of dry weather and with an absolute certainty of no rain during your trip.



The access situation at Mossdale Caverns is slightly complex following a serious incident in the 1960s which resulted in the entrance being sealed (but soon after reopened by cavers). For decades, access to Mossdale Caverns was robustly refused by the landowner and the gamekeepers. However, advice that the CNCC has received by regular visitors since 2010 onwards suggests that the situation has mellowed and the gamekeepers are now accepting of access. The cave is on access land and the route of approach from Yarnburn or Conistone (Yarnbury offering the easiest approach with the least uphill) is entirely via public footpaths and access land. The CNCC recommends that if visiting Mossdale, and you meet any gamekeeper, be polite and open about your intentions. Heed the flood warning!
