Not all trails in this area permit mountain bikes. Check it first. The rangers over there are zealots.

Wales offers a vast network for gravel biking, with over 380 routes documented on komoot. These range from easy, scenic loops to challenging multi-day adventures across diverse terrains.
You'll find incredibly varied terrain, from serene reservoir loops and sweeping forest tracks to rugged mountain passes. Expect ancient Roman roads, remote drover's tracks, and extensive fire roads. Areas like Eryri (Snowdonia) National Park feature dramatic mountainous terrain and glacial landforms, while the Elan Valley offers lush forests and dams. The Bannau Brycheiniog (Brecon Beacons) provides hills, valleys, and wild moorlands.
Yes, Wales has options for all skill levels. For an easier ride, consider the Brenig cycle trail — Llyn Brenig, which offers a gentle loop around the reservoir. The Elan Valley also features the Elan Valley Trail, built on old railway lines, providing a more relaxed experience.
For those seeking a significant challenge, the Trans Cambrian Way Loop is a demanding multi-day adventure traversing the remote Cambrian Mountains. Another difficult option is the Talybont-on-Usk loop from Blaenavon, winding through the varied terrain of the Bannau Brycheiniog (Brecon Beacons National Park).
Wales's trails often lead through stunning natural landscapes. You might encounter dramatic waterfalls like Swallow Falls or Henrhyd Falls. The region is also home to impressive gorges such as Devil's Kitchen (Twll Du) and the scenic Aberglaslyn Pass. Many routes pass by beautiful lakes, including the iconic Cwm Idwal, and offer views from summits like Fan Brycheiniog.
Yes, many routes in Wales are designed as loops, allowing you to start and finish in the same location. Examples include the Rhossili loop from Swansea in the Gower National Landscape, or the Ride the Clwyds: Loop de Loop in the Clwydian Range.
Spring and autumn generally offer the most pleasant conditions for gravel biking in Wales, with milder temperatures and beautiful scenery. Summer can be great, but trails might be busier. Winter riding is possible, especially on lower-elevation routes, but be prepared for colder, wetter weather and potentially challenging trail conditions.
Absolutely. Many areas, particularly around reservoirs and in forest parks, offer gentler, well-maintained tracks suitable for families. The Elan Valley Trail, built on old railway lines, is a good example of a route that provides a safe and scenic experience for all ages.
Many trails in Wales are dog-friendly, especially those on public bridleways and in forest parks. However, it's always best to check local regulations for specific routes, particularly within National Parks or nature reserves, as some areas may require dogs to be on a lead or have restricted access to protect wildlife or livestock.
While many routes benefit from car access, some areas in Wales are reasonably accessible by public transport, especially those near larger towns or railway lines. For example, routes within the Bannau Brycheiniog (Brecon Beacons) or near towns like Machynlleth (for the Nant y Moch loop) might have public transport links. Always check local bus and train schedules in advance.
The gravel biking experience in Wales is highly rated by the komoot community, with an average score of 4.6 stars from over 370 reviews. Riders frequently praise the dramatic and varied landscapes, the extensive network of trails, and the sense of immersion in nature that these routes provide.
Beyond the well-known trails, the remote Cambrian Mountains offer vast open spaces and untouched landscapes, providing a true sense of discovery for gravel bikers. The Gower Peninsula, the UK's first AONB, also features rolling hills and ancient sites with less-trafficked gravel tracks, offering both coastal and inland riding away from the crowds.
