The walk

The walk starts from the car park at the entrance to the Craig Cerrig-gleisiad national nature reserve on the A470. A path goes in through the gate into the cwm under the cliffs, climbs to a viewpoint, and goes on up to the rim of the crag, 629 m, where it meets the Beacons Way. It comes down by a different path to the road. The cliffs hold arctic-alpine plants such as purple saxifrage and green spleenwort, at the southern edge of their range in Britain.

It is 4.4 km with 346 m of ascent; allow about 2½ hours. The grade is Moderate.

The paths are steep and rocky in places and not suitable for prams or wheelchairs. The cliffs are high, and the rim is exposed to wind and often in cloud: take a map and compass in poor weather. Sheep graze the reserve, so keep dogs on a lead, and stay on the paths: the plants on the ledges are fragile.

Parking is at the reserve entrance on the A470: the OpenStreetMap car park shows no fee. The Bannau Brycheiniog National Park Visitor Centre, with toilets and a café, is a short drive up the road.
