This route was planned by komoot.
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.
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.
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.
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.
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.
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.

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.
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.
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.
