This route was planned by komoot.
This loop is considered a difficult touring bicycle ride. It covers approximately 65 km (40 miles) with significant elevation gain, around 780 meters (2,560 feet). You should have very good fitness, as there are challenging climbs, including sections that might require pushing your bike, especially towards the Black Mountains.
The terrain is varied, primarily consisting of quiet paved roads and peaceful country lanes. While mostly paved, some segments may be unpaved or have compacted gravel sections. Be prepared for undulating hills and demanding ascents throughout the ride.
You'll encounter several notable spots. In Brecon, you can see the Brecon Castle and the Brecon Canal Basin. The route also passes the Brynich Aqueduct and follows parts of the Monmouthshire and Brecon Canal. In Hay-on-Wye, explore Hay Castle and the Hay-on-Wye Clock Tower. The views of the Black Mountains and the Wye Valley are also highlights.
The best time to cycle this loop is generally from late spring to early autumn (May to September). During these months, you'll typically find more favorable weather conditions, longer daylight hours, and the stunning scenery of the Brecon Beacons National Park at its best. Be prepared for changeable weather regardless of the season.
You can typically find parking in both Brecon and Hay-on-Wye. Brecon, being a market town, offers various public car parks. It's advisable to check local council websites or apps for specific parking locations and fees before your visit. Starting early can help secure a spot.
While much of the route is on quiet country roads, which can be suitable for dogs on a lead, some sections may involve busier roads or areas with livestock. Always keep dogs under close control, especially near farm animals, and be mindful of other cyclists and road users. Consider the distance and difficulty for your dog's fitness level.
No, you do not need a permit or to pay an entrance fee to cycle this route within Bannau Brycheiniog (Brecon Beacons) National Park. The park is open access for activities like cycling on designated routes and public rights of way. However, always follow the Countryside Code, respect private land, and leave no trace.
For a touring cyclist, the route is estimated to take around 4 hours and 15 minutes of active cycling time. However, given its difficulty and the scenic points of interest, many cyclists choose to take longer, allowing for stops in towns like Hay-on-Wye and Talgarth, and to enjoy the views. Plan for a full day if you want to explore properly.
Yes, both Brecon and Hay-on-Wye offer numerous cafes, pubs, and shops where you can refuel. The village of Talgarth, roughly midway between the two towns, also has pubs and shops, making it a convenient pit stop. It's always a good idea to carry snacks and water, especially on the more remote sections.
Yes, the route incorporates sections of several well-known paths. You'll find yourself on parts of Lôn Las Cymru (South), EuroVelo 2 - Capitals Route, and National Cycle Network Route 42. It also briefly touches Lôn Las Cymru (Central) and the Monmouthshire & Brecon Canal towpath.
Due to its significant elevation gain, distance, and classification as 'difficult', this specific loop is not recommended for beginners or young families. It requires very good fitness and experience with challenging climbs. There are other, easier cycling options available within the wider Brecon Beacons area for those seeking a more moderate experience.
Given the challenging terrain and potential for changeable weather, pack essentials like a repair kit, spare inner tubes, pump, and basic tools. Carry plenty of water and snacks. Layered clothing, waterproofs, a helmet, and a fully charged phone are also crucial. Don't forget a map or GPS device, as phone signal can be intermittent in some areas.
