OM Dark Sky Park

Most of us live under ‘skyglow’, a sky which is illuminated by artificial light, known as light pollution. Not here.

Davagh, a natural cauldron in an ancient landscape.

A lack of light pollution at Davagh Forest means the night sky is at its darkest – and at its best to really see the stars.


Here  you will experience unrivalled and wondrous views of the night sky, one of only 78 places around the globe with official international dark sky accreditation. An amazing 80% of us live under ‘skyglow’, a sky which is illuminated mostly by artificial light, known as light pollution.

An International Dark Sky Park

OM Dark Sky Park and Observatory in Davagh Forest is the only one of its kind in Northern Ireland. It is one of two Dark Sky Parks on the island of Ireland and is the 78th area in the world to be accredited as an International Dark Sky Park.

“An International Dark-Sky Park (IDSP) is a land possessing an exceptional or distinguished quality of starry nights and a nocturnal environment, and that is specifically protected for its scientific, natural, educational, and/or cultural heritage resource, and/or for public enjoyment.”

Dark Sky Accreditation

Achieving Dark Sky Park accreditation takes years of careful monitoring of the darkness of the night sky, in all seasons, all phases of the moon and all weather conditions.


Data is gathered from ‘Unihedron Sky Quality Meters’ which measure darkness and are installed at various points in Davagh Forest.  The meters have shown measurements in excess of 21.75 magnitudes per square arcsecond.

Davagh Forest is one of the best places in the world to ‘go dark’!
