The Glenfinnan Viaduct, also known as the Harry Potter Bridge, is a picturesque railway viaduct located in the Scottish Highlands. This iconic structure with its 21 arches and stunning views over Loch Shiel has gained fame for its appearance in several Harry Potter films. Fans flock to see the Jacobite steam train cross the viaduct, but remember, it's not a good idea to try walking on it like in the movies! The viaduct is a must-visit spot for both railway enthusiasts and Harry Potter fans looking to experience a touch of magic in real life.
