The Nephin Beg Mountains Special Area of Conservation is a wild, rugged upland landscape in County Mayo offering pristine hiking opportunities, rich biodiversity, and an authentic wilderness experience.
Situated in northwestern County Mayo, Ireland, the Nephin Beg Mountains Special Area of Conservation is a vast and remote mountainous region characterized by extensive blanket bogs, heathlands, and upland lakes. The area is centered around the Nephin Beg mountain range, part of the larger Nephin Complex, with peaks reaching over 600 meters, including Knockmore and Nephin Beg itself. The landscape is shaped by glacial and post-glacial processes that have left a rugged terrain dotted with loughs and deep valleys, fostering diverse habitats for unique flora and fauna. This SAC protects important habitats like European dry heaths, blanket bogs, and oligotrophic lakes, which support species such as the red deer, hen harrier, merlin, and otter. Historically, this area has seen limited human settlement and is rich in archaeological features including ancient cairns and remnants of early pastoral farming communities. For outdoor enthusiasts, the Nephin Beg Mountains offer solitude and challenge with few developed trails, making it a prime spot for experienced hikers, backcountry camping, wildlife observation, and nature photography. The region is part of a larger network of protected areas that sustain Ireland’s biodiversity and natural heritage. Visitors can experience sweeping panoramic views from rugged summits and explore pristine bog ecosystems that are rare in Europe. This remote wilderness appeals to those seeking an unspoiled natural setting away from the more frequented tourist destinations.
