Recognize this bridge? The Glenfinnan Viaduct became one of the most iconic locations in the Harry Potter films, appearing as part of the Hogwarts Express route through the Scottish Highlands. In Harry Potter and the Chamber of Secrets , Harry and Ron fly above the railway in the enchanted Ford Anglia while trying to catch the Hogwarts Express. The real viaduct stretches across the Glenfinnan valley, surrounded by mountains and dramatic Highland scenery. It was also featured in later films in the series. Best time to visit Visit between late spring and early autumn for greener landscapes, longer daylight hours and the best chance of seeing a steam train cross the viaduct. For the classic viewpoint, follow the marked walking trail from the Glenfinnan visitor parking area. Arrive early because parking and viewpoints can become crowded, and check the current train timetable before travelling. Never enter the railway tracks. Quick tips: Best time: late spring and early autumn
