Magnificent structure and a great photo opportunity and one of many within the park.

Climbing the Rhigos northwards from Treherbert is a classic, sustained South Wales Valleys ascent featuring scenic hairpin bends and panoramic views. Settle into an endurance rhythm for the long climb averaging around 5%, but be prepared for steeper ramps hitting 10-15%, particularly on the iconic hairpin section midway up. Experience the dramatic scenery as you rise above the Rhondda valley onto the open moorland. The road surface is generally good following major repairs completed in late 2024, allowing you to focus on conquering this rewarding climb.

Climbing the Bwlch Mountain southwards from Treorchy (A4061) is a classic South Wales Valleys experience, offering a long, steady ascent. The road winds up from the Rhondda valley onto open moorland where the main challenge often becomes the significant exposure to wind. Enjoy the sweeping panoramic views from the top of this popular and rewarding climb.

The weir spans the River Taff, which flows directly through the heart of South Wales. It's a nice place to stop and refuel with picnic benches and a peaceful atmosphere.

An epic road bike climb that not very difficult & has stunning views as you ascend

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.
