Argyll and Bute Council wants to create a massive conservation area stretching from the tiny islands of Tiree and Coll all the way to the west Kintyre coast.
Covering an area of roughly 2650 square miles, it would become the UK’s largest National Park.
Although much of it would extend into the ocean, as Scotland’s first coastal park it would dwarf Loch Lomond and The Trossachs and would also be bigger than the Cairngorms, which sprawls across 1748 square miles of mountain terrain and is currently the largest in Britain.
Campaigners welcomed the plans, insisting they would “boost the image of Scotland, reinforce its image worldwide and increase the public’s commitment to conservation”.
John Mayhew, manager of Scotland National Parks Strategy Project, said: “We’ve been campaigning for four years. Having a National Park would look after our beautiful landscapes. It would encourage tourists to visit and spend money and it would create jobs for people in maintaining the park.”
