A spot famous for its feature in Harry Potter, the Glenfinnan viaduct sits tucked away in the mountains opposite Loch Shiel. If you get the time of day correct you may even be able to sit above the train line and watch the train pass. There are plenty of spots you can view the viaduct from and plenty of paths and walkways for you to trail down. The views are certainly not something you want to miss out on. If you’re planning on travelling to somewhere nearby you should unquestionably take a visit.
