Erris Head Special Area of Conservation (SAC) is a protected coastal region located in the northwestern corner of County Mayo, Ireland. This site is renowned for its striking sea cliffs composed of quartzite formations, which rise sharply from the Atlantic Ocean, creating a dramatic and wild landscape. The area covers a diverse range of habitats including maritime cliffs, coastal grasslands, heathlands, and small areas of blanket bog, supporting a rich biodiversity. Erris Head is particularly important as a breeding site for several seabird species, such as fulmars, kittiwakes, and cormorants, making it a prime destination for birdwatching. The coastal waters are also significant for marine life, including rare seaweeds and invertebrates.
Historically, the area reflects centuries of traditional fishing and low-impact farming practices, sustaining a landscape that remains relatively untouched by modern development. Visitors are attracted to Erris Head for its spectacular ocean views, peaceful walking trails, and opportunities for wildlife observation, especially the seasonal bird migrations and marine mammal sightings. While not formally developed for extensive recreational infrastructure, the rugged pathways and open landscapes provide challenging yet rewarding hikes.
Erris Head is part of a larger Natura 2000 network, emphasizing habitat conservation and ecological balance. Its remote location imparts a sense of solitude, ideal for outdoor enthusiasts seeking unspoiled nature. The area appeals to photographers, naturalists, and those interested in the intersection of geology and coastal ecology.
