Glen

Glen Lyon

Scotland's longest enclosed glen — 56 kilometres of single-track road, ancient trees, river pools, and the oldest yew tree in Europe at its entrance.

Glen Lyon runs west from Fortingall for 56 kilometres, gradually narrowing from a broad agricultural valley into a tight defile before ending at the Loch Lyon dam. It is the longest enclosed glen in Scotland. The diversity of landscape along its length is striking: the lower glen is green and farmed, with the famous Fortingall Yew in its churchyard and the wide River Lyon winding through flood meadows; the middle glen tightens around Bridge of Balgie; the upper glen becomes moorland, reservoir and high deer forest.

The Munros on the north side of the glen — Stuchd an Lochain, Meall Buidhe — are rarely busy. Ben Lawers (1214m), the highest Munro in the southern Highlands, is technically accessed from the south via the A827, but the Lyon gives access to its quieter flanks. The glen road is single-track throughout and becomes very narrow beyond Bridge of Balgie — the inner glen in particular is unsuitable for anything larger than a standard car. There is no through-route: you must return the way you came, or take the single high pass road over to Killin.

Single-track with passing placesUnclassified (B846 to junction)

Single-track road etiquette

Pull into passing places to let oncoming vehicles pass. Don't park in passing places. If a faster vehicle is behind you, pull over and let them past. Do not reverse at speed — wait in a passing place.

Motorhomes — proceed with caution. The glen road is 56km of single-track. Motorhomes can reach the lower glen (Fortingall end) but the inner glen narrows considerably. Do not attempt full length.

End of road

Loch Lyon dam. The road follows the north side of the reservoir to the dam head.

What's in the glen

Fortingall Yew

The Fortingall Yew is reputedly the oldest tree in Europe — estimated between 2,000 and 9,000 years old. It stands in the churchyard of the small village of Fortingall at the entrance to the glen. Female flowers were observed on one branch in 2015 — the tree is changing sex.

Meggernie Castle

Meggernie Castle stands at the mid-point of the glen — a 16th-century tower house extended into a shooting lodge. It is a private residence. The glen road passes within sight of it.

River Lyon

Our take

Glen Lyon is the Perthshire glen that most people have never heard of and almost none visit properly. The drive the full length is worth doing once: take a full day, stop at the Fortingall Yew, have lunch at the Bridge of Balgie tearoom, and drive to the dam. The inner glen has a quality of quiet that is harder and harder to find. Don't take a motorhome beyond the lower glen — the road does not forgive mistakes and there is nowhere to turn.

History

Glen Lyon is the longest enclosed glen in Scotland — a 55km Highland corridor running from Loch Tay to the high ground above Loch Lyon. Its remoteness preserved an unusual concentration of pre-historic and early-medieval remains: ring forts at Fortingall, the Iron Age dùn on the south side of the glen, the carved stones of the old Fortingall churchyard, and the Fortingall Yew — one of the oldest trees in Europe, dated by tree-ring analysis to between 2,000 and 5,000 years old.

The glen is the historic territory of Clan Campbell of Glenlyon and the MacGregors. The 1692 Glencoe massacre was carried out under the orders of Robert Campbell of Glenlyon — a fact still remembered locally. The hydro scheme at Loch Lyon (the Breadalbane Scheme) was built between 1957 and 1961 and transformed the upper glen, raising water levels and submerging the old township of Pubil. The drowned road and ruined farms remain visible at low water. The Allt Conait pass at the head of the glen is the historic drovers' route across to Rannoch.
