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.

Situated in the beautiful wilderness between the Breacon Beacons and the Black Mountain overlooked by the hills of Fan Fawr and Fan Gihirych, Maen Llia is a truly massive sliver of rock. While it is over 3.5 metres tall and nearly 3 metres wide, it is only 75 centimetres thick and bears a striking resemblance to a giant Neolithic hand axe. Although it is aligned north to south, the sides of the rock become surprisingly warm to the touch on a sunny day. This must have been an important pass between the hills, both to the local prehistoric population and to the Romans who came this way some 3000 years later - they built the road 'Sarn Helen' right by the stone and the current road still follows part of its course.

According to legend, the stone goes down to the river, the Afon Llia to drink on occasion. This tall tale seems likely to be an allusion to the fact that its shadow is cast across the moorland as far as the river when the sun is low in the evening sky.
