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.
