Claerwen National Nature Reserve
Claerwen National Nature Reserve, located in Powys, Wales, features the impressive Claerwen reservoir and dam, which were the last additions to the Elan Valley Reservoirs system. Completed in 1952, the dam showcases a late Victorian design and is constructed primarily of concrete with a dressed stone exterior. This gravity dam, built on solid rock foundations, plays a crucial role in supplying water to Birmingham and the West Midlands. Wildlife enthusiasts can look for species such as the Barn Owl and Bog-rosemary, with the best time to observe these species being in July around 01:00. Cowberry can also be spotted, particularly in November. The reserve offers a unique opportunity to appreciate both its historical significance and the diverse flora and fauna that thrive in this stunning landscape.
