This challenging touring cycling loop is approximately 57 kilometers (35 miles) long. Komoot estimates it takes around 4 hours to complete, but this can vary significantly based on your fitness level, the weather, and how often you stop to enjoy the views.
The terrain is varied and often challenging, characteristic of the Bannau Brycheiniog National Park. You'll encounter significant ascents and descents, including hilly and mountainous sections around Mynydd Llangynidr. Surfaces can be mixed, ranging from mostly paved roads around Talybont Reservoir to single-lane roads with grassy centers and potential gravel sections. Wider, more durable tires are advisable.

Winter cycling is possible but requires appropriate gear and caution due to colder temperatures and potential for icy conditions on higher elevations.
While dogs are generally welcome in Bannau Brycheiniog National Park, this specific touring cycling route is designed for bicycles and covers significant distances on roads and mixed surfaces. If you plan to bring a dog, ensure they are fit enough to keep pace, are comfortable with being carried in a suitable bike trailer for long periods, and are kept on a lead around livestock and in populated areas. Always carry water for your dog.
