About Clew Bay Natural Heritage Area

Clew Bay Natural Heritage Area encompasses a stunning coastal and marine environment renowned for its hundreds of islands, rich biodiversity, and cultural heritage, offering exceptional opportunities for outdoor recreation and wildlife observation.

Wilderness Landscape & Natural Heritage

Clew Bay Natural Heritage Area is a distinctive coastal region located in County Mayo on Ireland’s west coast. Known primarily for its breathtaking archipelago of around 117 islands, the area features a unique combination of marine, coastal, and terrestrial habitats. These islands and the surrounding waters provide sanctuary to a variety of rare and protected species, including otters, seals, and internationally important seabird colonies like terns and eiders. The bay's geology consists largely of limestone, creating a rich marine ecosystem with diverse underwater flora and fauna, including significant oyster beds and seagrass beds that serve as nursery grounds for fish. Historically, Clew Bay is steeped in cultural importance, with remnants of ancient monastic sites, castles, and old fishing villages scattered throughout the area, reflecting centuries of human interaction with the landscape. Outdoor enthusiasts are drawn to Clew Bay for kayaking among its calm waters and islands, hiking scenic coastal trails with panoramic views, birdwatching opportunities, and fishing. The surrounding countryside also offers car tours on coastal roads that reveal spectacular views and historical landmarks. The area’s relatively mild but wet climate supports lush greenery and an ever-changing seascape, making it a favorite spot for photographers and nature lovers alike.
