Lough Conn and Lough Cullin SPA is a vital wetland habitat in County Mayo, recognized for its rich biodiversity and crucial role in supporting wintering and breeding waterfowl, offering excellent opportunities for nature observation and birdwatching.
Located in County Mayo, western Ireland, the Lough Conn and Lough Cullin SPA encompasses two large freshwater lakes connected by a narrow water channel near the town of Castlebar. These lakes and their surrounding wetlands provide an important habitat for a wide variety of bird species, particularly waterfowl such as whooper swans, teal, pochard, and various species of ducks, making the area internationally significant under the EU Birds Directive. The SPA includes extensive reedbeds, marshes, and wet grasslands supporting breeding waders and other aquatic bird species. The mild Atlantic climate and relatively flat terrain make the area accessible and welcoming to visitors year-round. Historically, Lough Conn and Lough Cullin have supported local fisheries and traditional livelihoods, while today they serve as a cultural and natural landmark for the region. Outdoor enthusiasts can engage in wildlife watching and scenic walking along lakeshore paths, with ample opportunities for photography and fishing, following local regulations. The nearby towns of Castlebar and Ballina provide visitor amenities and serve as gateways for exploring the SPA. The area’s quiet rural charm combined with exceptional bird diversity attracts both casual visitors and birdwatching specialists. Protection efforts focus on maintaining water quality, preserving natural vegetation, and managing human activity to ensure the SPA remains a refuge for its resident and migratory species.
