Craig y Cilau: Crags and Caves

Highlight • Natural Monument

The walk along Craig y Cilau is a pretty special experience. The imposing rock faces of the limestone escarpment are home to a really diverse variety of rare wild plants. Add to this a variety of bird life and bats in some of the extensive cave systems found here and you really do have a nature reserve to enjoy.

You will find some steep sections to test your strength, and likely some muddy and slippery paths, so come appropriately prepared.

Ogof Ffynnon Ddu Nature Reserve is named after a cave that lies under Carreg Cadno's northern slopes. Translating as the Cave of the Black Spring, this is the deepest cave in the United Kingdom, reaching 901 feet (274.5 m) under the surface.

Not that much to add here, basically this is a great place to go on a rainy day, or to visit as a rest stop on a bike ride up the Swansea Valley. There is also a great nearby campsite/motorhome venue stay, if you are thinking of staying overnight.

As well as the caves, here you have Porth yr Ogof car park, or Cwm Porth car park, to give it its proper name. It's one of the better car parks, with toilets and a small shop. On most days there is also hot food and drinks available. The famous Four Waterfalls walk also starts from here. This is a spectacular walk, and each waterfall is great in its own way. They are Sgwd Clun-Gwyn, Sgwd Isaf Clun-Gwyn, Sgwd y Pannwr, and Sgwd yr Eira.
