A completely unassuming road that isn't wide or busy enough to warrant road markings but offers up one of the best (and quietest) views of the Western Brecon Beacons or Carmarthenshire Fans. The name comes from the black rocks characteristic of these hills. Underneath these rocky shelves are the Lakes of Llyn Y Fan Fawr and Llyn Y Fan Fach so it's likely the only cars you'll see are those parked up by walkers!

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).
