Adam Price has developed a splendid highball face in the vicinity of Castle Rock of Triermain. From Castle Rock it’s 300m south across the bracken fields, with the corner of the face being visible on the approach.

The wall features three good problems with the central line being the pick of the bunch. Thirlmere Regime (7B!) is the better part of 6m, with the crimpy face getting progressively harder the higher you get.
Adam’s written up the crag and problems on UKClimbing.com and also included a topo. So there’s no excuse not to get this spot on your list!
