I'd been to Culter Fell from Glenkirk, however Nigel Rose, who knows this area well, suggested the approach from Culter Water would be much more enjoyable. And he was right. Once up on the higher ground, this route took the form of a circuit around Coulter Reservoir following fence-lines. The running was a joy with straightforward navigation and fine views, particularly to Tinto. What lovely names these hills have - Gathersnow, Hudderstone, Moss Law.
