The historic Dyfi Bridge (Pont ar Ddyfi) near Machynlleth dates back to 1805, following earlier timber and stone structures from 1533 and 1681. It served as the main A487 crossing until it was permanently closed to vehicles in February 2024 and replaced by a new £46 million modern viaduct upstream to prevent frequent flood closures.

There are over 30 dedicated no-traffic gravel bike trails in Powys featured in this guide. The majority of these, 27 routes, are rated as difficult, offering a significant challenge for experienced riders, while 5 routes are moderate.
Powys offers an extensive network of ancient routes, remote drover's tracks, and fire roads, particularly in areas like the Elan Valley and Cambrian Mountains. Its sparsely populated nature means many trails are naturally free from vehicle traffic, providing a serene and challenging gravel biking experience amidst stunning Welsh landscapes.
Yes, Powys is home to several long-distance gravel routes. For an epic challenge, consider the Elan Valley Reservoirs – Caban-Coch Dam and Reservoir loop, which spans over 120 km. Another significant option is the Trans Cambrian Way Loop, covering approximately 77 km through rugged terrain.
Many routes traverse areas rich in natural beauty. You can encounter stunning reservoirs and dams, particularly in the Elan Valley, such as the impressive Caban-Coch Dam and Reservoir. The region also features beautiful lakes like Llyn y Fan Fawr and the scenic Craig-y-Nos Country Park and Castle, offering picturesque views and tranquil settings.
Absolutely. Many of the best no-traffic gravel trails in Powys are designed as circular routes, allowing you to start and finish in the same location. Examples include the challenging Nant y Moch loop from Machynlleth in the Cambrian Mountains, or the Mach 1, 2, and 3 Loop, which offers a substantial ride.
The komoot community highly rates the no-traffic gravel trails in Powys, with an average score of nearly 5 stars. Riders frequently praise the remote and wild feel of the routes, the stunning natural scenery, and the sense of escape from traffic, particularly highlighting the challenging yet rewarding terrain of the Cambrian Mountains and Elan Valley.
While the focus is on natural landscapes, some routes may offer glimpses of historical interest. For example, the area around Machynlleth, a historic market town, serves as a starting point for routes like the Machynlleth Clock Tower – Tony the Tiger Trail loop. You can also explore highlights like Castell Dinas Hillfort and Castle Ruins or Crickhowell Castle ruins, though these might require a short detour from the main gravel paths.
Spring and autumn generally offer the most pleasant conditions with milder temperatures and beautiful scenery. Summer is also popular, but trails can be busier. Winter riding is possible for experienced riders, but be prepared for colder, wetter conditions and potentially challenging surfaces due to the region's rugged nature.
Given that 27 of the 32 routes are rated difficult, riders should expect challenging terrain. This often includes rocky surfaces, significant elevation changes, and remote sections. Good fitness, advanced riding skills, and appropriate gear are recommended. Always check weather conditions before heading out, as they can change rapidly in the Welsh mountains.
The very nature of 'no traffic' routes in Powys often means they are less crowded than paved roads. The vastness and remote character of areas like the Cambrian Mountains and parts of the Brecon Beacons ensure a sense of solitude. Choosing routes rated as 'difficult' also tends to lead to fewer fellow riders.
Access to some trailheads by public transport can be limited due to the remote nature of many routes in Powys. While larger towns like Machynlleth or Builth Wells (near the start of the Elan Valley Reservoirs – Caban-Coch Dam and Reservoir loop) have train or bus connections, reaching the more secluded starting points often requires personal vehicle transport. Always check local transport schedules and bike carriage policies in advance.
