The walk

The walk starts from the car park at the end of the lane above Carreg Cennen Castle. It goes by the castle, which stands on a limestone crag above the River Cennen, then follows paths and tracks down the valley, on the Heart of Wales Line Trail for part of the way, to Llygad Llwchwr, the spring where the River Loughor rises. It returns up the valley the same way, with the castle on the skyline.

It is 5.5 km with 221 m of ascent; allow about 2 hours. The grade is Easy.

The ground is open farmland with sheep and cattle: keep dogs under control and close the gates. Paths can be muddy and the track down to the valley is steep in places. The castle's cave passage and steps, and the crag edge, are not part of this walk.

The car park has no fee shown in OpenStreetMap. The castle is looked after by Cadw; the walk goes by it and does not need a ticket.
