Embark on a challenging touring bicycle adventure through the Brecon Beacons National Park with the 3 Reservoirs loop. This difficult 48.6-mile (78.1 km) route, designed to take around 5 hours and 26 minutes, features a significant 3578 feet (1091 metres) of elevation gain. You will cycle past the beautiful Talybont, Pontsticill, and Llwyn-onn reservoirs, enjoying expansive views of the water features and surrounding hills. Be prepared for a mix of paved surfaces and some unpaved or gravelly sections, including a notable gravelly climb near Talybont Reservoir.
This loop is best suited for touring cyclists with very good fitness due to its considerable climbs, especially the notorious Devil's Elbow. While the route is primarily paved, some segments, like the Devil's Elbow itself, have a crumbling surface and neglected barriers, so suitable tires are recommended. You might also encounter cattle grids along the way. Planning your visit for good weather will enhance your experience, allowing you to fully appreciate the rugged scenery and isolated wilderness.
The Devil's Elbow is the defining feature of this trail, a legendary and brutal ascent known for its steep gradients, averaging 10% with sections reaching 14% and even over 30% on its vicious switchbacks. Conquering this climb is a significant achievement for cyclists, often featured in events like the Dragon Ride sportive. Beyond the challenge, you will discover ancient landmarks like the Maen Llia Standing Stone near the summit, adding a unique historical layer to the diverse landscapes of rolling moorlands and river valleys.

the lower reservoir has a nice flat road next to it, a welcome relief after the lumpy roads that lead to it from either direction.
