With many miles of dedicated and graded gravel roads, plus almost endless off-road links, it’s the perfect place to hone your off-road skills on an Adventure Bike. Wide open spaces in the heart of the Plynlimon mountain range, with no other traffic, means time to learn and practice in safety and peace. We’ve set out 3 specific routes and loops for Adventure Bikes, Trail Bikes and a “hard” rally for the most advanced and adventurous riders. The tracks cover a huge area, running to almost 20 miles in length over a huge variety of terrain, from mountains and moors to forests and valleys, it’s off-road heaven!
