These are a handful of short freshwater caves within Croisaphuill / Balnakeil Formation limestones, located upstream of the Allt Ach a’ Chorrain from ‘Little Bridge’ near the southern end of the Kyle of Durness (Streetview). Knee pads are recommended due to the numerous small nodules of chert and differentially dissolved fossil burrows that protrude from the rocky floor like ‘coral’ (although there is sand cover in places).
The most obvious of these (Uamh an Coireil / Coral Cave) is found at the base of a cliff section where the river splits into left & right parts (left hand wall of the right hand steam valley). This is a draughting tube that continues for a total of 35m, mostly a simple hands and knees crawl but one that eventually requires some awkward flat-out crawling over boulders to reach ‘Scorpio Chamber’ before the whole thing eventually chokes.
One cave known Uamh As Eugmhais Crioch is located further upstream from this. Although it becomes too tight for anybody after 65m, the Gaelic name means ‘Cave That Never Ends’ as it is one of the most notorious caves in Scotland for being tight and arduous… which would be bad enough without it frequently flooding to the roof and having to dam the stream to gain entry. If you’re an experienced and incredibly masochistic caver, then this may be the very cave for you!
Along the separate left hand valley and beyond Uamh nan Clachan Dubhan, a double opening on the north bank of the streambed is known as ‘the Nostrils’. These lead into a very narrow rift that goes on through water for ~10 metres before becoming too tight. Another short cave with another tight entrance can be found diagonally opposite this in the southern bank of the surface streambed.
