Wild Nephin National Park, National park with dark skies in County Mayo, Ireland
Wild Nephin National Park is a protected area in northwest County Mayo covering mountains, blanket bogs, grasslands, and river systems that reach toward the Atlantic coast. It also carries designation as an International Dark Sky Park and a Special Area of Conservation, giving it overlapping layers of protected status.
The park was founded in 1998 as Ballycroy National Park following a European directive requiring the protection of specific natural environments across Ireland. In 2016 it was renamed Wild Nephin National Park and its boundaries were extended to cover a larger area.
The Bangor Trail cuts through the Nephin Beg mountains along a path where farmers moved their livestock through the uplands for generations. Walking it today means moving through a landscape shaped by that long use, still largely unchanged.
A visitor center in Ballycroy village opens seasonally and is a good starting point before heading into the terrain. Warm and waterproof clothing is a must, as the weather in this open landscape can change quickly at any time of year.
The park's blanket bogs have been storing carbon for thousands of years and are among the oldest living ecosystems on the island. A thin layer of peat can contain organic material that is several thousand years old, still preserved beneath the surface.
