A steep and rewarding 6.2 mile out and back route form the campsite at Cwmdu to Pen Cerrig Calch, a 701m Hewitt or Nuttall (hill).

The route leaves the campsite and climbs, through and interesting farm with a resident stone mason, and up onto the open land of the hill itself.  A steep climb up the escarpment brings you to Pen Gloch-y-pibwr and a large stone cairn.  From here the ridge can be followed all the way to the summit.

Looking northwards, you can see Pen Allt-mawr, a touch higher at 719m.

A quick brew here is always nice so you can sit back and enjoy the fantastic views whle the kettle is boiling.

The route back is simply retracing your steps.

Once back at the campsite, it's a short walk to the Farmers Arms for a quick pint.
