About Cambrian Mountains Area of Outstanding Natural Beauty

 

The Cambrian Mountains Area of Outstanding Natural Beauty (AONB) covers a sweeping expanse of upland terrain in mid-Wales, encompassing parts of Ceredigion, Powys, and Carmarthenshire. Often referred to as the 'Green Desert of Wales,' the region is characterized by extensive moorlands, rounded hills, deep valleys, and numerous reservoirs formed by glacial and river activity. Its geography includes high plateaux, peat bogs, and fast-flowing rivers, with the peaks of Plynlimon and the Elenydd uplands among the highest points, providing breathtaking vistas. The area's ecology supports a variety of habitats including heather moorland, native oak woodlands, and freshwater wetlands, which sustain rare wildlife such as red kites, otters, and black grouse. Historically, the region has been sparsely populated, dominated by sheep farming, and shaped by small-scale mining and forestry activities, contributing to the rugged, unspoiled nature of the landscape. Visitors are drawn to the Cambrian Mountains for its solitude, contrasting with more crowded destinations, and for outdoor activities like hiking its network of trails, mountain biking on rugged terrain, fishing in its rivers and reservoirs, and birdwatching. Notable landmarks include the Plynlimon range, sources of the rivers Wye and Severn, and man-made features such as the Claerwen and Clywedog reservoirs. The area's low light pollution and remote setting also make it a popular spot for stargazing. Its combination of wild geography, ecological richness, and cultural heritage makes the Cambrian Mountains AONB a unique destination for nature lovers and outdoor enthusiasts seeking peace and natural beauty.
