Spend a few moments on the bridge over the River Sawdde river to take in the view. A great bird watching spot, if you are patient or lucky enough you may see Sandpipers, Dipper or Kingfisher here.

Black Mountain Climb from Pont Aber

Highlight (Segment) • Climb

Although not the classic side of the Black Mountain, this is still a fantastic road to climb that crosses the spine of the mountain and immerses you in some of the best scenery Wales has to offer.

It’s a kilometre into the slope before you escape Brynamman and enter the open land but from then on it is pure bliss. After two kilometres the road bends left as it rises above the valley below on your right. Meandering across the featureless landscape, exposed to whatever mother nature has in store the majestic strip of tarmac gradually makes its way towards the summit.

With no markers on the horizon, no sharp bends or features to focus on the ascent is a test for the mind and body. Grind out whatever gear you can on the consistent 6-7% slope all the way to the exposed plateau then get ready for the exhilarating descent.

Frequently Asked Questions

How challenging is this cycling loop?

This route is classified as a "difficult" racebike ride and is best suited for experienced and fit cyclists. It features significant elevation gain, including the continuous 6-7% gradient of the Black Mountain Climb, and is rarely flat. Expect a demanding but rewarding experience.

How long does it typically take to complete this cycling loop?

Komoot estimates the duration for this specific 76 km route to be around 4 hours and 5 minutes of active cycling time. However, given its challenging nature and significant elevation, cyclists should plan for a total experience closer to 5-9 hours, especially if including stops for rest and enjoying the views.

What is the terrain like on this cycling route?

The route primarily features mostly well-paved surfaces, though some segments might be unpaved and difficult, contributing to its "Hard road ride" classification. The ascent up Y Mynydd Ddu (Black Mountain) involves a switchback road (A4069) with a consistent 6-7% slope leading to an exposed plateau. The overall terrain is rarely flat, with both short, sharp climbs and more gradual, prolonged ascents.

What scenic highlights can I expect along the way?

This route is celebrated for its dramatic landscapes and epic views of Wales. Key highlights include the thrilling Black Mountain Climb from Pont Aber, which offers extensive vistas from its exposed plateau. You'll also pass the View of the River Sawdde at Llangadog Common. The Black Mountain Road (A4069) itself is considered one of the most scenic routes in the UK, providing fantastic views along the ridge.

Where can I park to start this cycling route?

While specific parking locations are not detailed, Ammanford and Llandovery are common starting points for this loop. You would typically look for public parking facilities within these towns to begin your ride.

What is the best time of year to cycle this route?

The best time to cycle this route is generally during the spring, summer, and early autumn months when weather conditions are more favorable. The exposed nature of the Black Mountain means it can be very windy and cold outside of these seasons. Always check the weather forecast before you go, as conditions can change rapidly.

Are there any cafes or places to refuel along the route?

Yes, you can find places to refuel. The route passes by Coaltown Coffee Roasters, which is a great spot for a coffee break. Llandovery and Ammanford, the towns at either end of the loop, will also offer various options for cafes, pubs, and other amenities.

Does this route intersect with other well-known paths?

Yes, sections of this route overlap with several other paths. You will encounter parts of the Heart of Wales Line Trail, Cycle across the Beacons, and the Amman Valley Cycleway. Smaller sections also coincide with the Cambrian Way, Beacons Way, and Black Mountain Quarries Walk.

Do I need a permit or pay an entrance fee to cycle in Bannau Brycheiniog National Park?

No, you do not need a permit or to pay an entrance fee to cycle this route within Bannau Brycheiniog National Park. The park is open to the public, and access to roads and public rights of way is generally free. However, always respect local regulations and private land.

Is this cycling route suitable for families or those with dogs?

This route is a difficult racebike loop and is not recommended for families with young children or those seeking a leisurely ride. Due to the demanding terrain, significant climbs, and the nature of road cycling, it is also generally not suitable for dogs, who would struggle to keep pace or be safe on the roads.

What kind of gear should I bring for this ride?

Given the route's difficulty and exposed sections, you should bring appropriate gear for a challenging road ride. This includes a well-maintained racebike, a helmet, suitable cycling apparel for varying weather conditions (layers are recommended), plenty of water and snacks, a repair kit, and navigation tools. Be prepared for potential wind and rapid weather changes on the Black Mountain.
