Fell’s Swoop is only a short cave and doesn’t take very long to explore, so isn’t necessarily worth a special visit. However it can easily be tacked on to a caving trip to Eglwys Faen or Agen Allwedd for an extra slice of underground adventure.

From Whitewalls, walk along the tramroad in the direction of Agen Allwedd for about 400 metres and look for a small quarry on the left-hand side obscured by grassed-over spoil heaps. The entrance to the cave cannot be seen from the tramroad and is a 2m high rift in the cliff face with walled spoil heaps on either side.
The muddy entrance rift reduces to a crawl to meet a junction. To the right, two crawls lead off, the lower ends quickly but the upper becomes very tight after around 15m but looks passable beyond. The main way on is up a short climb to a crawl which closes down over gour pools after 30m. The end of the cave has been extended slightly and is currently intermittently being dug by CSS members.
