    Mountain biking

    While views are great, the route is not suitable for gravel bikes as there’s a mix of medium and large rocks, had to spend too much time walking this section

    Sarn Helen is an old Roman Road which belies the notion that they're all straight! Here, it's a wide, well-surfaced track which affords extensive views of the surrounding countryside.

    Sarn Helen and Twyn y Gaer loop — The Brecon Beacons National Park

    Embark on the Sarn Helen and Twyn y Gaer loop for a challenging mountain biking adventure through the Brecon Beacons National Park. This moderate 19.9-mile (32.0 km) route, which you can complete in about 2 hours and 40 minutes, features a significant 2086 feet (636 metres) of elevation gain. You will start from the village of Heol Senni, climbing alongside a river through twisted trees, encountering two sharp hairpins before reaching a brow with expansive views. The trail offers a mix of roads, paths, and technical singletrack, promising fast and frenetic riding. From the summit of Twyn y Gaer, you can enjoy 360-degree panoramic views of the Brecon Beacons and Black Mountains, including Pen-y-Fan, Corn Du, the River Usk, and surrounding farmland.

    When planning your visit, be aware that the paths leading to Twyn y Gaer can become boggy, especially after wet weather. The exposure to the elements can also increase the challenge, so check the forecast before you go. This loop requires good fitness and advanced riding skills due to its significant climbs and technical sections. Starting your ride from Heol Senni provides direct access to the varied terrain, which includes tarmac, gravel tracks, and singletrack.

    This route integrates sections of the ancient Sarn Helen, a historic Roman road system, allowing you to ride through a landscape rich in history. Twyn y Gaer itself is the site of an Iron Age hillfort, adding another layer of historical interest to your ride. The Sarn Helen and Twyn y Gaer loop is part of a larger network considered one of Britain's most ambitious off-road rides, making it a rewarding experience for mountain bikers seeking a challenging adventure with breathtaking natural and historical scenery.
