A spelunker’s dream, the cave underneath Carreg Cennen Castle requires a somewhat precarious hike along the cliff face to access. Once there, a bright torch or flashlight is needed to see through the dark caverns. Finding one’s way to the hidden cave is boast worthy, as the difficulty deters many a would-be adventurer. When visiting the castle ruins, head for the cliff side to discover the secret cave. Find the set of steep stone steps and make your descent. Next, venture through a tunnel that leads to the dark cave beyond. Explore the cave for as far in as you wish. It is said that it leads all the way to the village of Trap which the castle overlooks.
