    Road cycling

    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).

    Black Mountain, Devil's Elbow & Usk Reservoir loop from Llandovery

    2,000m

    Embark on a challenging racebike journey through the Bannau Brycheiniog National Park with the Black Mountain, Devil's Elbow & Usk Reservoir loop. This difficult 71.7-mile (115.4 km) route will test your endurance as you climb 6574 feet (2004 metres) over approximately 6 hours. You will experience expansive moorland and rugged peaks, with panoramic views across the Towy Valley. Expect dramatic scenery and serene water views around the Usk Reservoir.

    This demanding road cycling route requires a very good level of fitness. Be aware that some initial segments for the Black Mountain climb from Pont Aber might be unpaved, which can be difficult for road bikes. The A4069 section can also be narrow with traffic, so stay alert and plan your ride carefully. Ensure you are prepared for a full day on the saddle.

    This loop is renowned for its iconic climbs, including the Black Mountain Pass, which many compare to the Alps, and the notorious Devil's Elbow. As you ride, you might spot wildlife like Red Kites, especially near the Usk Reservoir. The route offers a unique opportunity to immerse yourself in the rugged beauty of the Welsh landscape.
