Catching the train in motion has become harder as the crowds grow, so the surest way to guarantee a sighting is to join a guided tour that times your arrival around the crossing.

How to see the Jacobite Steam Train
The Jacobite Steam Train runs from Fort William to Mallaig and back and operates between the end of March and October. The direction of travel determines the best viewpoint at the Glenfinnan Viaduct: if the train is travelling from Fort William, position yourself to the left of the viaduct, and if it is travelling from Mallaig, head to the right. Ask staff if you are unsure.
The hilly viewpoints get muddy regardless of the weather, so wear appropriate footwear. The car park fills up quickly, so arrive early whether you are self-driving or on a tour that stops there. Check the current timetable before you travel, as crossing times shift through the season.

Frequently Asked Questions
Which city is best for a Glenfinnan Viaduct tour?
It depends on your priorities. Edinburgh offers the most tour choice and the classic Highland route but the longest day; Fort William is only 30 minutes away and lets you time your visit precisely, even catching both train crossings. Glasgow and Inverness sit in between.
Is the Jacobite the same as the Harry Potter train?
Yes. The Jacobite Steam Train was used as the Hogwarts Express in the Harry Potter films, and its crossing of the Glenfinnan Viaduct features in several of them, which is why the viaduct draws so many fans.
When does the steam train cross the viaduct?
The Jacobite runs between late March and October, typically crossing the viaduct mid-morning on its outbound run to Mallaig and again in the afternoon on the return. Always check the current seasonal timetable before you travel.
Can I visit the Glenfinnan Viaduct without a tour?
Yes, you can drive yourself and walk to the viewpoint, but the car park fills up fast in summer and parking is limited. A guided tour removes the driving and parking stress and times your arrival around the train.
