Elan Valley Reservoirs SSSI is a protected area in mid-Wales known for its stunning reservoir system, rich biodiversity, and extensive outdoor recreation opportunities like hiking, fishing, and wildlife observation.
The Elan Valley Reservoirs SSSI is a designated Site of Special Scientific Interest located in Powys, Wales, encompassing a series of man-made reservoirs and surrounding natural habitats. Created in the late 19th and early 20th centuries to supply water to Birmingham, these reservoirs—namely Claerwen, Caban Coch, Garreg Ddu, and Craig Goch—are set within a landscape that combines rugged moorlands, woodlands, and freshwater ecosystems. The area is recognized for its ecological significance, supporting a range of bird species such as red kites, peregrine falcons, and various waterfowl, alongside rare plants and important upland habitats. Beyond its ecological value, Elan Valley offers many outdoor recreation opportunities including scenic walking and cycling trails, fishing in stocked waters, and photography. The iconic dams and Victorian-era aqueduct infrastructure add historical interest. Visitors can explore the visitor center, learn about the water supply engineering, and enjoy quiet natural settings. The SSSI’s combination of natural and engineered features makes it an important conservation area as well as a popular destination within Wales for day outings and longer outdoor adventures.
