Name and dates

Glenfinnan Viaduct (1901-)

Opened on the Mallaig Extension (West Highland Railway).


This viaduct is one of the highlights of the Mallaig Extension. It is much photographed both from the train and the surrounding land.

It is a single track viaduct of mass concrete on a curve. It has 21 arches and is 100 ft high. It is the longest concrete viaduct in Scotland at 416 yds. It is on the rise to a summit to the west, required by the climb up from Eil past Glenfinnan to cross the high ground before dropping down to Loch Eilt. Without this climb such a large viaduct would not have been needed.

It was initially a striking white colour, considered a bit of an imposition on the landscape, but has darkened and mellowed looking more like weathered stone.

It is at the south end of Glenfinnan and crosses the River Finnan.

In relatively recent years, it has featured in the Harry Potter films.

The view of the viaduct from most directions is largely clear of trees and can be easily photographed. It is a short walk from the Glenfinnan Visitor Centre, or the even closer Glenfinnan Viaduct Car Park just off the A830 on the west bank of the Finnan (the road up to the viaduct is private). The hillock above the visitor centre affords a good view (the "Glenfinnan Viewpoint") and a longer circular walk can be had from the centre to the viaduct, then along the rougher hillside footpath to Glenfinnan station and back to the centre by either the A830 taking in the St Mary's and St Finnan's Chapel or via the minor road which drops down from the Prince's Hotel

Glen House, seen in older photographs and which sat to the north of the viaduct, no longer stands having been demolished in the 1970s.

13.65 miles from Banavie Junction [2nd].

It is reached by train about 30 minutes after leaving Fort William. If you are planning to take a photograph from the Jacobite train it would be advisable to find a suitable window much earlier, perhaps around Locheilside station. The viaduct can be seen from the left (when heading to Mallaig) side of the train.
