Wilderness Landscape & Natural Heritage
Lough Allen Special Area of Conservation (SAC) encompasses the waters and surrounding habitats of Lough Allen, the uppermost lake on the River Shannon and one of Ireland’s largest lakes by surface area. Located mainly within counties Leitrim and Roscommon with a small part extending into Cavan, this SAC protects a diverse range of habitats including oligotrophic waters, alkaline fens, bogs, and shoreline marshes. The lake is characterized by clear oligotrophic waters with underlying bedrock and extensive reed beds along its shores, supporting a wide array of aquatic plants and animals. Notably, it hosts populations of rare fish species such as the critically endangered European eel (Anguilla anguilla), Arctic char (Salvelinus alpinus), and Atlantic salmon (Salmo salar). Birdlife thrives here, particularly overwintering wildfowl and breeding waders, making it important for conservation and wildlife watching. Recreational opportunities abound, with the lake and adjacent wetlands inviting anglers, kayakers, and nature enthusiasts. The tranquil waters offer excellent fishing, especially for trout, pike, and perch, while the surrounding landscape provides opportunities for hiking and wildlife photography. The area’s cultural history links to local Gaelic settlements and historical river trade routes along the Shannon. Visitor appeal stems from the combination of pristine natural habitats, scenic vistas, and peaceful recreation settings ideal for disconnecting from urban life. Overall, Lough Allen SAC is a crucial refuge for threatened species and a valuable destination for environmentally conscious recreationists.
