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.

Best side of the Bwlch to climb from, sharp kick to start up to the houses, then a bit of flat before the climb proper starts.
