Foel Fras and Llyn Anafon

The walk starts from the Mountain Gate car park at the top of the narrow road above Abergwyngregyn, at about 198 m. A path through the gate and a long stony track climb up the Afon Anafon valley to Llyn Anafon, the lake at its head, whose weir is the intake for the Anafon hydro scheme. From the lake a path climbs the ridge between Drum and Foel Fras to the summit, Foel Fras, 944 m, the eleventh-highest summit in Wales, at the north end of the high Carneddau. You return the same way.

It is 12.5 km there and back with 740 m of ascent; allow about 5½ hours. The grade is Hard.

This is high, open mountain: the summit plateau is wide and flat, paths are faint on the upper hill, and cloud makes it easy to lose the way, so take a map and compass and boots. The Abergwyngregyn community says to allow 2 to 2.5 hours to walk back from the lake and to finish before dark. The narrow road up to the car park has descending traffic, so take care driving up.

The car park at the top is free, says the Abergwyngregyn community's page. There is no café or shop on the route.
