Took a rope which was useless for the leader (no gear) but protected the second on 3 occasions.
Far more serious than the grade suggests, the main difficulties are where the gill becomes impassable and you have to escape up vertical grass with rock that disintegrates when touched.
At the first main fall the guidebook suggests an escape up a grassy gully and ramp on the left; this is dangerous, I'd recommend avoiding this bit completely by a big loop to the right. Higher up where the guide refers to a technical traverse, this is about 4b, can be avoided by a wade with an exit on friable rock. Don't relax too much near the end where it says "easy little falls follow" - the second of these was one of the hardest of the route and a rope was used.
Worthwhile but not to be underestimated (and like most routes in that book, subtract a star). Simon Caldwell - Solo - 05/Jun/12 with Carmen

An adventure! Still grinning several hours later. Not that hard but very long and fairly sustained. Serious in places but generally escapable. Done in a dry spell, much would have to be avoided in higher water. Iain Thow - Solo - 05/Oct/01 with Ben Lowe
