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.ย 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.

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. The nature reserve itself is a wild-feeling moorland landscape with many rocky outcrops. It enjoys splendid views of the region's peaceful countryside. The reserve protects the wildlife that thrives in this unique environment. Bats and moths populate the caves, while above ground peregrines and red kites hunt in the sky. Early summer is a majestic time to explore here, when flowers like mountain everlasting, autumn gentian, mossy saxifrage and great burnet show off their colours.
