This road is a firm favourite with those who know it - which is surprisingly few. Enjoy the spectacular views across the Brecon Beacons and Carmarthenshire Fans, with good quality tarmac under your wheels and only occasional car traffic. The approach from Trecastle to the North is about a 7km climb, with an elevation gain of 259m, and an average gradient of 3.7%.

Fabulous climb and I agree that it's best from south to north. (Although I would say it's also a more enjoyable descent heading south...) Naturally beautiful and wild. Very quiet. Unexpectedly smooth tarmac. One of my favourite UK climbs.

Spectacular. Peaceful. Sometimes eerily quiet. Little to no traffic and a decent road surface. All adds up to one of the most spectacular and unassuming climbs in the Brecon Beacons (best climbed from the south).
