      Cwmcarn Forest is the destination for all you downhill adrenaline junkies. The Y Mynydd course consists of one man-made downhill Trail (with a choice of lines on the top and middle sections), simply named red run and black run. The course demands a high level of skill (and guts). These are extreme downhill trails and are suitable for experienced riders only.

      You’ll be challenged with loads of berms, a few switch backs, doubles, a tunnel, rock steps, the bridge, hip jump and the quarry gap. The jumps are there if you want them,
      but can be ridden around if not. An uplift pass is available at www.cwmdown.co.uk.

      Cwmcarn Forest is also home of the Twrch Trail, this is a superb 15.5km trail of the very highest quality that is not for the faint hearted. Virtually the entire route is on purpose built single-track through a mixture of broadleaf and conifer woodlands and open ridge tops.

      The riding varies from open and flowing hard pack to tight technical & Rooty and is rideable in all weather, with a steep climb at the start followed by a rollercoaster decline with dramatic views of the Bristol channel and surrounding hills.

      The Twrch Trail and uplift service start from the car park.
