The Great Glen Way stretches for 118.5km from coast to coast across the Highlands, linking the main centres of Fort William and the regional capital of Inverness. The route follows the major natural faultline of the Great Glen which divides Scotland from coast to coast. Most of the route keeps to lower levels and offers a good introduction to the Highlands and to long distance walking; since 2014 there has also been a higher level option between Fort Augustus and Drumnadrochit which offers more dramatic views at the cost of a little more effort. The Way runs along the complete lengths of Loch Lochy, Loch Oich and the forests above Loch Ness, as well as along the towpath of the Caledonian Canal, an engineering marvel built by Thomas Telford that links these lochs and creates a through route from the western seaboard to the Moray Firth.
Starting at the end of the West Highland Way, the Great Glen Way provides a natural continuation of a longer journey through the Highlands. It is also possible to link the route with the unofficial East Highland Way.
