This difficult trail, estimated to take 6 hours and 49 minutes, offers expansive landscapes and rolling hills, often called the "desert of Wales." You will navigate a mix of top-quality gravel tracks, rocky singletrack, and ancient ridge roads, with the serene Teifi Pools and the impressive Claerwen Dam in the Elan Valley as notable landmarks along the way.
Planning your ride requires self-reliance due to the trail's remote nature and limited facilities. You should be prepared for varied conditions, including numerous river crossings that may require dismounting your bike. Boggy sections can appear, especially after rain, so consider the weather forecast before you go. Factor in potential delays from gates along the route, and remember that carrying a water filter is highly recommended to ensure you stay hydrated throughout your journey.

The Cambrian Mountains themselves are known for their vastness and isolation, offering a true escape into nature.

Originally a motte and bailey Norman castle, only the earthwork mound and ramparts remain now. The castle is accessible by public footpaths from the nearby village of New Radnor and the castle still command a ranging view over the village and countryside. The castle's former use as a gaol ensured New Radnor's status as the former County Town before that status was moved to the larger Presteigne.
