The creator of Scotland's first end-to-end walk which starts in the Borders says it could turn out to become of the world's most iconic long distance treks.
TV presenter and outdoors enthusiast Cameron McNeish believed a long distance walk from one end of the country to the other was lacking and got the idea from a visit to Nepal.
First Minister Alex Salmond will officially launch the 470-mile-long Scottish National Trail.
The route starts at the village of Kirk Yetholm on the English border and takes in the capital and both national parks at Loch Lomond and The Trossachs before finishes at the most north-westerly point at Cape Wrath.He accepts that his national trail will only be for the most enthusiastic of hikers.
