It is brilliant to travel it all the way from Glasgow to Mallaig, but it also makes a really great day out from Cuil Bay and environs. Take the train from Fort William or Bridge of Orchy and get off at Corrour, the remotest station in Britain.
There is a bar/restaurant at the station with great food and a cosy fire. It is open all day if you just want to hang out by the fire. Take a walk to Loch Ossian (about a mile), and one of the most remote youth hostels in the UK. Or walk to the other end of the loch to see the extraordinary home of the tetrapack heiress (woods great for hedgehog mushrooms).
If you are serious walkers then the walk from Corrour east across the moor to Rannoch Station or north to Tulloch, is a great adventure. There are also a number of Munroes in the area that you may be able to get up and back before the train returns.
Just make sure you don’t miss the train back! The train times can be found here
