From the start there is an obvious path ascending gradually to CP1,
from where it is up to you what line you take to the summit of the
Cribyn. You must descend the valley, cross the stream and make the
steep ascent to join the path taking you up the Cribyn's north-east
ridge. The last few hundred feet are steep and rocky.
From the Cribyn summit (CP2) follow the Beacons ridge in a westerly
direction, descending the flank of the Cribyn to the pool and
continuing up to the summit of Pen-y-Fan (CP3). The path to the
highest point in South Wales is obvious- having dimensions
reminiscent of the M4. Again there is a final scramble to the top.
Take the north ridge off Pen-y-Fan and enjoy the long fast descent
down Cefn Cwm Llwch. The route is pretty obvious all the way to the
finish.
