A good pit-stop when you are out riding with an old guy called Peter James. Sometimes he'll get the cakes in!

Starting in the outskirts of Rhigos, this climb takes you past former mining areas and up to the top of Hirwaun Common. The climb passes the fomer Tower Colliery – which used to be the oldest working deep coal mine in the UK but closed in 2008. The climb gives both a feeling of industrial heritage but later the sweeping views of the Hirwaun Common. The first few km are fairly straight but near the summit, there are two switchback hairpins which add an alpine feel to this long-steady climb.

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.

Nice fast descent from the stone bridge at the bottom of the Blaen y Glyn climb along the west shore of the reservoir.

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.

If you don't fancy the long gravel trail on the East shore, this is your tarmac option.
