The third film was the first to extensively utilise real - life locations, as much of the first two films had been shot in the studio. Some sets for the film were built in Glen Coe, Scotland, near the Clachaig Inn. The indoor sets, including ones built for the previous two films, are mainly in Leavesden Film Studios. The Hogwarts Lake was filmed from Loch Shiel, Loch Eilt and Loch Morar in the Scottish Highlands. Incidentally, the train bridge, which was also featured in the Chamber of Secrets, is opposite Loch Shiel and was used to film the sequences when the Dementor boarded the train. A small section of the triple - decker bus scene, where it weaves in between traffic, was filmed in North London 's Palmers Green. Some parts were also filmed in and around Borough Market and Lambeth Bridge in London.
