The Great Glen is also known as Glen Albyn or Glen More. It runs from Fort William at the head of Loch Linnhe to Inverness on the edge of Moray Firth following a natural geological fault known as the Great Glen Fault, and bisects the Scottish Highlands into the Grampian Mountains to the southeast and the Northwest Highlands to the northwest. Much of the glen is taken up with a series of lochs (in order from south to north) Loch Linnhe, Loch Eil, Loch Lochy, Loch Oich, Loch Ness, and Loch Dochfour. The catchment area of the freshwater lochs is huge and they are fed by many rivers that drain great mountain areas particularly to the north and west. The Caledonian Canal also uses the lochs as part of its route, but the rivers feeding them are not navigable.
The Great Glen Way, a long-distance route for cyclists and walkers, was opened in 2002 and consists of a series of footpaths, forestry tracks, canal paths and occasional stretches of road linking Fort William to Inverness. An extension to the way, known as 'The High Route', was constructed in 2015 linking Fort Augustus to Drumnadrochit offering excellent and extensive views to the south and west including Ben Nevis and the mountains of Knoydart and Kintail.
