Cefn-coed Viaduct was built in 1866 and is 770 ft (235 m) long and 120 ft (36.6 m) high. It is a rusticated-limestone structure of fifteen arches, set on a curve. The tall, slender piers and parapets are constructed with coursed irregular sized rock-faced limestone blocks

The Cefn-coed Viaduct is the third-largest viaduct in Wales. This huge, curved structure once carried the Brecon and Merthyr Tydfil Junction Railway and is now part of the Taff Trail, which is Route 8 of the National Cycle Network that runs between Cardiff and Brecon. It offers walkers and cyclists a superb view of the Taf Fawr as it cascades over the many weirs in the valley

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 β 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.

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.
