Coll is the second area in Scotland to be recognised – behind Galloway Forest Park – and the sixth in the UK.
The island has no street lighting and is relatively free of light pollution found in built up urban areas. Islanders, who number about 200, now hope the recognition will lead to a surge in winter tourism. Galloway Forest Park has seen a rise in off-season tourism since it was recognised in November 2009.
Coll was awarded the status of Dark Sky Community by the International Dark-Sky Association at the same time as Northumberland Park in England. The other UK sites with the status are Sark Island, Exmoor Reserve and the Brecon Beacons.
