The Scottish National Trail is a long distance route running from south to north along the length of Scotland from Kirk Yetholm to Cape Wrath. It was devised by outdoors writer and broadcaster Cameron McNeish and in doing so he has created a challenging route with an accummulated amount of climbing measuring over 20,000 metres. The route combines sections of other well known long distance walking routes including St Cuthbert’s Way, the Southern Upland Way, the Forth and Clyde and Union Canals, the West Highland Way and the Rob Roy Way. The way also travels through the heights of Perthshire, the Cairngorms and the Northwest Highlands which makes it a strenuous and difficult undertaking both physically and mentally. Long stretches of walking have neither waymarking or a continuous path as well as a number of potentially hazardous river crossings. The walk increases in difficulty and severity as it heads to Cape Wrath in the far heads north-west.
