The Berwyns are one of the largest areas of upland heath in Wales, carpeted in heather and bilberry. The views from the summit ridge and across U-shaped valleys carved by ancient glaciers are fantastic. Start from pretty Llandrillo, looking L, take the R fork and then second R, following the quiet road to the farm at its end. Continue on the path S through woodland then SE across open moorland, climbing steadily onto the main ridge. Reaching the ridge, turn right and continue to climb, eventually reaching the trig point at the summit of Cadair Berwyn. From summit head WNW on obvious path down ridge to reach stream at Nant Cwm Tywyll before contouring N to return to outward path. Turn L to return to Llandrillo. CAUTION: Stream crossing may be difficult after heavy rain.
