Rated the 7th hardest climb in Wales (according to the FIETS index). The climb is about 5km, averaging just over 8% grade. As you'll be warmed up, it's no problem that about 500 metres from the start there is a steeper 2.5 km segment at about 10.5%. Don't let sheep or exhausted cyclists get in your way.

This is a spectacular climb in the Brecon Beacons located to the south of the River Usk valley. The climb is gradual and fun thanks to the switchbacks – a rare find in the UK! You reach the summit at 1,829 feet (557 m), but there are fantastic views all the way up and down.
