Uamh an Claonaite (Scottish Gaelic: Cave of the sloping rock) is the longest cave in Scotland.
[2] It consists of a series of dry passages and a series of at least six sumps which have been dived over the years.
[3] The attempt by members of the Grampian Speleological Group to excavate a nearby sinkhole, Rana Hole, and connect into the final chambers from above[4] achieved its aim in December 2007.
[5] The length of the cave is 2,868 metres (9,409 feet) and the vertical range is 110 metres (360 ft).
