Fort William to Mallaig in 60 Seconds
The Fort William to Mallaig railway — officially the "Mallaig Extension" of the West Highland Line, opened 1 April 1901 — was voted the world's top rail journey by readers of Wanderlust magazine in 2009, ahead of the Trans-Siberian and the Cuzco–Machu Picchu line. You can travel it two ways in 2026: the Jacobite steam train (the Harry Potter "Hogwarts Express," run by West Coast Railways, about 2h 10m each way, return only from £76 standard / £116 first class adult) or the year-round ScotRail diesel service (about 1h 24m, singles from around £5 Advance, roughly 4 trains a day).
Both trains cross the same 21-arch Glenfinnan Viaduct and the same coastline past Loch Eil, Loch nan Uamh, Arisaig, the Silver Sands of Morar and Loch Morar — so the scenery is identical. Choose the Jacobite for the heritage steam experience, ScotRail for flexibility, frequency and a fraction of the price.
For the best views, sit on the left-hand side travelling Fort William to Mallaig (right-hand side coming back). The 2026 Jacobite season opened late, on 1 June, and it attracts around 70,000 passengers a year — book ahead, as it sells out weeks in advance in summer.
The Jacobite (steam)
- Seasonal: 1 June–23 October 2026, 1–2 services a day
- ~2h 10m each way; same-day return only
- £76 standard / £116 first class, plus booking fee
- Heritage carriages, Harry Potter factor, sells out fast
ScotRail (diesel)
- Year-round, roughly 4 trains a day (1 on Sundays)
- ~1h 24m; singles, returns and flexible tickets
- From around £5 Advance, no booking fee
- Same viaduct, same views, a fraction of the price
This leg is also the highlight of the wider West Highland Line, which continues on to Glasgow and Oban. For the full Jacobite picture — timetable, fares and booking before it sells out — see our complete 2026 Jacobite guide, and for the viaduct itself, our Glenfinnan Viaduct guide.

Route History: Robert McAlpine's 1901 Extension
The stretch of railway from Fort William to Mallaig is officially the Mallaig Extension of the West Highland Line. Authorised by Royal Assent on 31 July 1894 and opened on 1 April 1901, it was built by Robert McAlpine & Sons to connect the fishing grounds of the west coast to the railway network, so herring could reach markets such as Billingsgate in London. McAlpine earned his nickname "Concrete Bob" for the pioneering mass-concrete structures — most famously the Glenfinnan Viaduct — used because the local hard mica schist defeated conventional stone-cutting.
The line has a ruling gradient of 1 in 40, eleven tunnels and several spectacular concrete viaducts. It's around 41–42 miles one way — West Coast Railways markets the Jacobite trip as an "84-mile round trip" — and forms part of the scenic "Road to the Isles." Readers of Wanderlust magazine voted the West Highland Line the world's top rail journey in the magazine's 2009 Travel Awards, ahead of the iconic Trans-Siberian Railway and the Cuzco-to-Machu Picchu line in Peru.

The Full Route: Every Stop From Fort William to Mallaig
What you pass, in order, heading west.
Fort William
The start — the largest town in the West Highlands, at the foot of Ben Nevis (1,345 m), Britain's highest mountain. The terminus also serves the Caledonian Sleeper from London and ScotRail from Glasgow.
Banavie & Corpach
Just after leaving town, the line crosses the Caledonian Canal on the Banavie swing bridge (built 1901), crawling past at 5 mph beside Neptune's Staircase — Thomas Telford's flight of eight locks, the longest staircase lock in Britain. At Corpach, the line runs along the shore of Loch Eil with views back to Ben Nevis.
Loch Eil Outward Bound & Locheilside
Two small request stops continuing along the loch, before the line begins its approach to Glenfinnan.
Glenfinnan — the highlight
The train sweeps onto the Glenfinnan Viaduct: 21 arches, 100 ft high, curved over the River Finnan — the Harry Potter "Hogwarts Express" location. Below stands the Glenfinnan Monument (1815), marking where Bonnie Prince Charlie raised his standard in 1745, with Loch Shiel stretching away. See our full Glenfinnan Viaduct guide for viewpoints and crossing times.
Lochailort & Loch nan Uamh viaduct
A small village station, then an 8-arch concrete viaduct where Bonnie Prince Charlie landed in 1745 and finally departed Scotland in September 1746 — the Prince's Cairn marks the spot nearby. Scanning in 2001 confirmed a legend of a horse and cart entombed in the concrete during construction.
Arisaig
The most westerly mainline railway station in Britain, with views to the Small Isles — Rum, Eigg, Muck and Canna — and the southern tip of Skye.
Morar
Home of the Silver Sands of Morar, white beaches used in Local Hero and Highlander, and Loch Morar — the deepest freshwater loch in the British Isles at 310 m.
Mallaig
Journey's end: a working fishing port with ferries to Skye, the Small Isles and Knoydart, excellent seafood, and the free Mallaig Heritage Centre beside the station.
The Jacobite Steam Train (2026 Timetable & Fares)
Operated by West Coast Railways, internationally famous as the Hogwarts Express, and attracting around 70,000 passengers a year.
2026 fares (same-day return only): £76 adult standard / £116 adult first class; £43 / £76 child (16 or under); Private Table for 2 (first class) £252 — plus a minimum £3.75 booking fee. Passengers get roughly 1h 45m in Mallaig. 2026 note: the season opened later than usual (1 June) after a Central Door Locking dispute, and the train has been running mixed carriage stock — check current details at westcoastrailways.co.uk. Full timetable and ticket advice in our complete Jacobite guide.

Jacobite Steam vs ScotRail Diesel: Which to Choose?
ScotRail crosses the exact same Glenfinnan Viaduct and coastline as the Jacobite — you simply don't have steam haulage or vintage carriages.
Which to choose? If the steam locomotive and the "Hogwarts Express" experience are the point of your trip, take the Jacobite — but book early. If you want flexibility, a lower price, more departures, or you're travelling outside June–October, take ScotRail via scotrail.co.uk. Many travellers do the best of both: ride the Jacobite one way for the experience and ScotRail the other, buying a separate ScotRail ticket since the Jacobite is return-only.
Getting to Fort William to Start
Wherever you're travelling from, here's how to reach the start of the line.
From Glasgow
Direct ScotRail trains from Glasgow Queen Street take about 3h 53m (from £38.80 return) — among the most scenic approaches in Britain, joining the West Highland Line proper.
By car
Fort William sits on the A82 north of Glasgow, about 2½–3 hours. Parking at the station is free but limited (around 50 spaces); long-stay town car parks are better for multi-day stays.
Caledonian Sleeper
From London Euston, reaching Fort William around breakfast time — useful for catching the morning Jacobite, though arriving the night before is safer.
Best side of the train
Sit on the left-hand side travelling Fort William to Mallaig for the curve onto the Glenfinnan Viaduct, Loch Eil and the coastal views; sit on the right for the return. Remember Fort William is a terminus, so the train reverses there.
Driving the A830 instead
The "Road to the Isles" runs parallel to the railway and takes about 45 minutes to an hour, passing Glenfinnan, Lochailort, Arisaig and Morar — though parking in the small villages is limited in summer.
Edinburgh Day Tours Covering Glenfinnan & Fort William
The most popular way to see this stretch without driving yourself, if Fort William isn't your starting point.

- Round-trip coach from central Edinburgh
- The Glenfinnan Viaduct and Loch Shiel ("the Black Lake")
- Glencoe's dramatic mountain scenery
- Free time in Fort William for lunch

5 Recommendations for the Fort William–Mallaig Journey
What experienced travellers do differently.
Decide steam vs scenery-on-a-budget first
Want the Hogwarts Express experience? Book the Jacobite at westcoastrailways.co.uk as early as possible — it sells out in summer. Want flexibility and value, or you're travelling November–May? Take ScotRail — same views, from around £5.
Confirm carriage type for 2026
Carriage stock has varied this season. If the vintage carriage matters to you, confirm details with West Coast Railways before paying.
Sit on the left going out, right coming back
Aim for a window seat that lines up with a seat bay for the clearest photos of the viaduct.
Build in time at Mallaig
Pre-book a wildlife cruise or a Skye ferry day-return if that's your goal — the Jacobite's roughly 1h 45m window is tight for anything beyond the harbour, a meal or the Heritage Centre.
If plans change
If the Jacobite is sold out and steam is non-negotiable, switch to ScotRail and watch the Jacobite cross Glenfinnan from the free NTS viewpoint instead. Want to visit multiple stops, such as Glenfinnan and Morar? ScotRail's flexible day return is the only option that allows breaking the journey.
