Here's one for all the Harry Potter fans out there!
Glenfinnan Viaduct is situated in the Highlands of Scotland not far from Fort William and is a must see for all. Such beautiful scenic views and if you are lucky you can time it with the Jacobite steam train passing through to capture the perfect shot.
There are various points to stop on the way to see the viaduct. The walk to the top is probably about 30 minutes. Parking available in two car parks nearby too.
