Train buffs will be left weak at the knees after travelling aboard the legendary trains of Scotland. Climb far-flung valleys, huff and puff across high ledges and skirt romantic green glens where roads are almost non-existent on the iconic Kyle Line and the West Highland Line. Then there’s the magical Jacobite Steam Train experience, which was featured as the Hogwarts Express in the Harry Potter films.
Make your way to Neptune’s Staircase, an impressive set of eight locks operated by a team of at least three lock keepers. Situated on the Caledonian Canal, the 22-ton lock gates were originally hand-powered, but are now operated by hydraulics.
