The late 13th-century ruins of Carreg Cennen Castle are perched on a great limestone crag, some 300 feet above the river Cennen. The view of the castle from the edge of this cliff also provides a stunning view of the Wales countryside.

The climb up to the castle is not too strenuous, and you will pass many grazing sheep and cattle along the way. The ruins are quite impressive, and include access to a cave beneath the outer ward of the castle. Well worth a visit!
