Parked at Claerwen Reservoir by the dam and took the good track along the north bank. Left this at 842660 and went across mainly pathless terrain to the summit of Llethr Hir. Difficult boggy and tussocky so tried to return to 842660 a lower route which was better to start but then got even worse. Not exactly an easy stroll. Returned along track and left it on path at 883652 for a short way before leaving it and heading straight for the summit of Craig Dyfnant. A little easier but still not easy. Then headed for Craig Fawr keeping a little left to reduce the amount of descent into the valley before striking out for the summit with a shortish final descent back to the track near the car park. 4 1/2 hours.clivevilla03/10/2017
