This is a strenuous route and the ground is rough underfoot in places, hiking boots are a must.
This is a nine and a half mile circular walk that visits four of the Beacons best loved peaks, Pen Y Fan, Cribyn, Corn Du and Fan Y Big. Penyfan is the highest peak in the Beacons at 886m and is a mecca to hillwalkers, we'd recommend doing this route mid week to avoid the crowds. Terrain covered includes mountain paths, open moorland, rough stoney tracks and a minor road.
There are no facilities along the route. There are shops, pubs and cafes in the nearby town of Brecon.
This area of the Beacons is home to many common varieties of birds, wildflowers, mosses and fungi.
