Olchon Valley Walk

The Olchon Valley. The landscape here features grassy slopes, ridgelines, and deep valleys, which are typical of the Black Mountains, offering a sense of solitude and immersion in nature. Starting from the village of Longtown, the walk takes you into the heart of the Olchon Valley, where you'll encounter a network of footpaths leading through farmland and grazing meadows. The route is particularly noted for its dramatic views of the surrounding peaks, including the towering Waun Fach and the ridge of Crug Mawr.

In addition, the surrounding woodland areas contain a rich variety of flora, with oak and ash trees lining the valley’s edges, while pockets of bluebells decorate the woodland floor in early spring. The journey through the Olchon Valley is a perfect blend of natural beauty, historical intrigue, and ample opportunities for wildlife watching.
