Great Glen Way: A Journey Through the Heart of the Scottish Highlands
The Great Glen Way (Scottish Gaelic: Slighe a' Ghlinne Mhòir) is one of Scotland's most iconic long-distance paths. Stretching 125 kilometres (78 mi) across the Highlands, the trail connects the town of Fort William in the southwest to the city of Inverness in the northeast. Established in 2002 and designated as one of Scotland's Great Trails by NatureScot, it offers a diverse landscape of canals, forests, and lochs.
Most travelers walk the route from southwest to northeast to take advantage of the prevailing wind. Depending on the mode of transport, the journey typically takes 5–7 days on foot or 2–3 days by bicycle. The path is a popular destination, attracting approximately 30,000 users annually, with about 4,500 completing the full distance.

Detailed Route Description
From Fort William to Laggan Locks
The journey begins at the Old Fort in Fort William, skirting the shores of Loch Linnhe toward Corpach before joining the Caledonian Canal. A highlight of this section is Neptune's Staircase, a series of eight locks that lift the canal to 19.2 metres (63 ft) above sea level. As the path reaches Loch Lochy, hikers leave the canal for forest tracks along the western shore, eventually reuniting with the canal at Laggan Locks.
For those seeking a greater challenge, a detour to visit nearby Munros (Scottish mountains over 3,000 ft) is possible, though this typically requires a full day.
Laggan Locks to Fort Augustus
From Laggan Locks, the route follows the towpath through Laggan Avenue to the Laggan Swing Bridge. After crossing the A82 road, the trail runs along the eastern shore of Loch Oich, utilizing parts of the former Invergarry and Fort Augustus Railway line. The path returns to the canal towpath at Aberchalder before entering Fort Augustus. Alternatively, the "Invergarry Link" provides a route along the western side of Loch Oich, offering easier access to local shops and accommodation in Invergarry.
Fort Augustus to Inverness
The final leg begins with a climb into the forests above the northwest shore of Loch Ness. After descending into Invermoriston and climbing again, the route passes through the hamlet of Grotaig. From there, the path leads through Clunebeg Wood to the River Coiltie and Borlum Bridge on the outskirts of Drumnadrochit.
After passing through Drumnadrochit, the trail ascends a steep hill to Abriachan, the route's highest point. The path traverses forest tracks through Craig Leach Forest, passing a reservoir before descending through the suburbs of Inverness. The journey concludes by following the canal and the River Ness into the city centre, finishing at Inverness Castle.
Recent Route Improvements
To enhance safety and comfort, the Highland Council implemented a new off-road section in early 2026. This improvement avoids a busy road south of Grotaig that was previously considered unsafe due to high traffic levels. The new section, which passes through the Bunloit Estate, officially opened in June 2026.
Water-Based Alternatives and Achievements
The Great Glen Canoe Trail
Parallel to the walking path is the Great Glen Canoe Trail, Scotland's first dedicated long-distance trail for canoes and kayaks. Launched in 2012, this 96-kilometre route is also a designated Great Trail. It takes between 3–5 days to complete and requires paddlers to portage (carry their craft) around 29 locks.
The Great Glen Swim
In July 2012, marathon swimmer Alina Warren became the first person to swim the Great Glen. She covered 117 km, utilizing the three lochs and the rivers Ness, Oich, and Lochy instead of the man-made canals.
Trail Connections
The Great Glen Way serves as a central artery for Scottish long-distance trekking, connecting to several other major routes:
- Fort William: West Highland Way, East Highland Way, and Cape Wrath Trail.
- Drumnadrochit: Affric Kintail Way.
- Inverness: John o' Groats Trail and South Loch Ness Trail.
