Black Mountain, Devil's Elbow & Usk Reservoir loop from Llandovery

This is a challenging road cycling route, classified as 'difficult' due to its significant length (over 115 km) and substantial elevation gain (around 2,000m). A very good level of fitness is essential to comfortably complete the loop, especially given the demanding climbs like the Black Mountain Pass and the Devil's Elbow.

The route primarily features well-paved tarmac roads. However, be aware that some initial segments for the Black Mountain climb from Pont Aber might be unpaved and difficult for a road bike. Around the Usk Reservoir, you'll encounter a mix of good compacted-stone forestry tracks and smooth, undulating tarmac roads. The road over Usk Reservoir is exposed and can be wild.

You'll encounter several notable points of interest. Key highlights include the challenging Black Mountain Climb from Pont Aber, the historic Maen Llia Standing Stone, and the notorious Devil's Elbow Climb from Heol Senni. You'll also pass through scenic mountain passes like Bwlch Bryn-Rhudd and Bwlch Cerrig Duon Pass, and enjoy stunning views from the Road Over Usk Reservoir, Bannau Brycheiniog National Park.

While the route starts from Llandovery, specific parking details are not provided. Llandovery is a small market town, and you should be able to find public parking options within the town center. It's advisable to check local council websites or parking apps for the most current information on parking availability and fees before your visit.

The best time to cycle this challenging route is typically from late spring to early autumn (May to October) when weather conditions are generally more stable and daylight hours are longer. Winter cycling can be very challenging due to cold temperatures, ice, and potentially severe weather in the exposed mountain sections.

Generally, there are no specific permits or entrance fees required for cycling on public roads and designated trails within Bannau Brycheiniog (Brecon Beacons) National Park. However, always respect local signage, private land, and any specific regulations that might apply to certain areas or events.

As this is primarily a road cycling route, it's not typically considered 'dog-friendly' in the traditional sense for walking. If you plan to bring a dog, it would need to be safely secured in a bike trailer or similar setup. For activities around the Usk Reservoir, dogs are generally welcome but should be kept under control, especially around livestock and wildlife.

Llandovery, as your starting point, offers various cafes, pubs, and accommodation options suitable for cyclists. The route itself passes through remote areas, so opportunities for refreshments directly on the loop are limited. It's best to carry sufficient food and water. The Usk Reservoir area is quite isolated, so plan accordingly.

The Black Mountain Pass is renowned as one of 'Britain's 100 Greatest Cycling Climbs,' offering a 'BIG Mountain feel' with long sweeping turns and spectacular views, often likened to the Alps. The Devil's Elbow is a 'notorious cycling challenge,' frequently featured in the Dragon Ride sportive. It's a brutal, relentless climb with steep gradients and sharp hairpins, providing a significant test for any cyclist.

Yes, the route briefly intersects with sections of other trails. You'll find it crosses parts of the Cycle across the Beacons, Cambrian Way, NCR 437 (Proposed), Heart of Wales Line Trail, and Beacons Way at various points along the loop.

While offering remote beauty, sections like the A4069 (Black Mountain Pass) can be a narrow two-lane road with a fair amount of traffic, especially during peak seasons. Always be vigilant, ride defensively, and wear appropriate high-visibility clothing. Road surfaces are generally good tarmac but can be exposed and wild in certain areas, particularly around the Usk Reservoir.
