International Dark Sky Week 2023 in Mayo


International Dark Sky Week 2023 with lots of events for our next Dark Sky Roadshow taking place right across Mayo!

International Dark Sky Week taking place from 16-22 April is a global affair, organised annually by the International Dark Sky Association. On this global stage, Ireland is playing a leading role, particularly in County Mayo, home of Mayo Dark Sky Park.

Mayo Dark Sky Park consists of the 15,000 hectares of the lands of Wild Nephin National Park, comprised of the wild lands surrounding the Nephin Beg Mountain Range. A very special and unique place, much loved by the close-knit rural communities surrounding it, where those communities have come together to plan a roadshow of the county, taking in the dark sky communities of Newport, Mulranny, Ballycroy and Achill Island and welcoming urban areas in Westport and Castlebar as well as new hosts in Blacksod for the first time!

Mayo is home to Ireland’s first International Dark Sky Park

We are so lucky here in Mayo, as we have some of the darkest skies in Europe, a resource that the world is starting to appreciate more and more, as excessive levels of artificial light continue to obliterate our view of the night sky. We are only now beginning to appreciate just how important natural skies are for our planet. Many of us think of science and stargazing when we think of the night sky, but it is also vitally important for biodiversity, human wellbeing and culture.

Each evening we visit a different community celebrating one of the facets of our dark sky story.
