This route was planned by komoot.
This route is classified as a "difficult" mountain bike ride, requiring very good fitness and advanced riding skills. You should be prepared for significant climbs, varied terrain, and potentially some "hike-a-bike" sections where you may need to push your bike. It's not recommended for beginners.
The terrain is quite varied, featuring excellent quality gravel tracks, unpaved sections, and some paved stretches. You'll encounter forest trails, quiet lanes, and singletrack. Be aware that some sections can be boggy, and there are rocky parts, loose stones, slabs, and drops, especially on more technical descents.
No, there are generally no specific permits or entrance fees required to access the Trans Cambrian Way: Claerwen Reservoir Loop. The area is part of the Elenydd SSSI (Site of Special Scientific Interest), but public access for activities like mountain biking is typically permitted without charge. Always respect local regulations and signage.
While specific parking locations aren't detailed, the loop is part of the larger Elan Valley area. You would typically look for parking near the Claerwen Reservoir itself or at designated parking areas within the Elan Valley, which provide access to the network of trails.
The best times to ride are generally during the drier months, from late spring through early autumn. This avoids the worst of the boggy conditions and offers more pleasant weather. Be prepared for changeable weather at any time of year in this remote Welsh landscape.
Yes, dogs are generally allowed on this trail. However, given the remote nature of the area and the presence of livestock and wildlife (including red kites and otters), it's crucial to keep dogs under close control, preferably on a leash, to ensure their safety and respect the environment and other users.
You'll experience stunning views of the Claerwen Reservoir, the largest of the Elan Valley's reservoirs. Highlights include the Gravel track along the Claerwen Reservoir, another Gravel Path Along Claerwen Reservoir offering magnificent views, and a Singletrack Descent with View of Lake and Hills. You can also catch a View of Strata Florida.
Yes, the route incorporates sections of several other trails. You'll find yourself on parts of the Trans Cambrian Way, Cambrian Way, Strata Florida, Teifi Pools Walk, and the Nantgwyllt Blue Flow Trail.
The remote Elan Valley is home to diverse wildlife. Keep an eye out for majestic red kites soaring overhead and, if you're lucky, you might spot otters near the water. The area offers a true sense of peaceful remoteness.
Mobile phone signal is often non-existent in this remote area, so don't rely on it for navigation or emergencies. There are no official water refill points directly on the trail, so it's essential to carry all the water you'll need for the duration of your ride.
The area around Claerwen Reservoir is very remote, so direct access to cafes, pubs, or accommodation immediately adjacent to the trail is limited. You would need to venture further into the Elan Valley or nearby towns for such amenities. Plan accordingly by bringing sufficient food and drink.
