things to do while waiting for the overnight train in Fort William

As well as the above, on your way to or from the distillery, you could take a Mallaig train one stop to Banavie for the railway swing bridge over the canal and Neptune's staircase flight of locks.

It's nice down at the ferry pier for the Loch views (although the ferry to Camusnagaul doesn't run on a Sunday).

If you caught the early bus you could take the lunchtime service train either to Mallaig and back (if you haven't 'done' the line) or to Glenfinnan, get off there, have lunch, see the monument, wander down to the Loch then the mid afternoon train back, getting off at Banavie as above.

The restaurant that used to be at Fort William Pier has moved to the new Highland Cinema and has had very good reviews- https://highlandcinema.co.uk/restaurant-bar/

I think the Gondola is only worth doing if the weather is good, so would decide that on the day.

Bear in mind that the Sleeper Lounge at the station opens at 4pm, and you will be boarding soon after 6pm.

Hello
Thank you! This is great information. We are taking the trains from Glasgow to Mallaig earlier that week. I didn't realize about the sleeper lounge. Good to know. The restaurant menu looks great. Once again, thank you!

There is a nice bookshop in Fort William.

Just a little bit out of town (bus? taxi?) is the headquarters of the Highland Soap Factory with their delightful shower gels, lotions, etc and attached cafe.

Oops in looking I see they also have a smaller shop in town.

All three are open on Sundays.

Hello
Oh, we love bookstores and the Highland Soap Co looks wonderful (just checked their website).
Thank you!

If you are prepared to walk, there's a nice walk around Fort William which takes you past the remains of the Old Fort and also the ruined Inverlochy Castle.

Following on from isn31c's suggestion, either catch the train to Banavie or catch a bus to Corpach and do the walk along the canal and Neptune's Staircase.

Both of these are nice easy bwalks.

Hello
Thank you. These two walks are perfect options.
Regards,
Suzanne

The walk to Inverlochy castle would take you right to the Highland Soap HQ shop and cafe.

Good to know.
Thank you!

prior to the train, there is a Morrisons supermarket right by the station that is generally open late for last minute essentials. The cafe though shuts at 5pm.

There is also a Premier Inn including a restaurant 350 metres from the railway station and a McDonald's on the route, 200 metres, for food before the train.

The McDonald's in Ft William is the one in traditional McDonald's land, and also IIRC was for a while the only one with signs in Gaelic.

Thank you!
Great options.

If you’ve got some time to kill before the sleeper, Fort William actually has a few gems! Grab a bite or a drink at The Grog & Gruel—cozy pub with good food. You can take a walk down to the loch for some peaceful views, especially around sunset. The West Highland Museum is also worth a quick visit if it’s still open. If you’re into hiking, a short wander up Cow Hill gives you a great view over the town and Ben Nevis. Otherwise, just soak in the scenery—Fort William’s pretty charming in the evening light!

Hello
Thank you for sharing those gems!
