The viaduct carries the Hogwarts Express in the film, and it is where the Dementor attack on the train takes place. Filming reused the Jacobite steam train, with some night sequences enhanced by effects. Today the viaduct is visible from public viewpoints with parking nearby, and the Jacobite still crosses in summer, so visitors can watch a real steam train make the same journey. It is one of the most popular Potter stops in Scotland.
The Short Answer
The film was mainly shot at Warner Bros. Studios Leavesden in Hertfordshire, England, with extensive location work in the Scottish Highlands and around London. Key exteriors include the Glenfinnan Viaduct for the Hogwarts Express, St. Paul's Cathedral's geometric staircase for Hogwarts interiors, and Glen Coe for Hagrid's Hut. The Knight Bus scenes were filmed on real London streets using a custom-built triple-decker bus.
Harry Potter and the Prisoner of Azkaban, released in 2004, marked a shift for the series. Alfonso Cuarón took over directing from Chris Columbus, the first change of director in the franchise, and he pushed the production out of familiar English locations and into the dramatic landscapes of the Scottish Highlands.
The result is a film with some of the most recognisable real-world locations in the whole series, from a loch-side viaduct in the Highlands to a cathedral staircase in the City of London. Almost all of them can be visited today, several for free.

Location By Location
The cathedral's geometric staircase doubled as a Hogwarts interior staircase, memorably after Divination class. St. Paul's is a working cathedral in the City of London with paid entry, and the staircase is accessible during visits. It sits close to other central London filming spots, including the Borough Market streets used for the Leaky Cauldron exterior, so it fits easily into a walking day in the capital.
This address in Borough Market provided the Leaky Cauldron exterior and the spot where the Knight Bus arrives with Harry. It is a street-level location, free to see from the public pavement, and sits inside one of London's best-known food markets. Visitors can combine a look at the facade with lunch or shopping in the market stalls that surround it on all sides.
Dowding Way in Watford, near Leavesden Studios, stood in for the Knight Bus pickup scene near Privet Drive. The street where Number 4 Privet Drive itself was filmed is also in this residential area, so both can be seen on the same short detour. As with all private residential locations, viewing is from the public road only, and residents ask visitors to be quiet and respectful.
Green Lanes in Palmers Green, north London, is where the Knight Bus races through the streets. The bus was a real custom-built triple-decker driven through London for filming rather than a visual effect. The road remains a busy public artery with safe sidewalk viewing, and it is close to other north London spots, making it a quick stop for completists working through the capital's Potter sites.
Hagrid's Hut was relocated from Black Park in England to the dramatic slopes of Clachaig Gully for this film, and the site of the Care of Magical Creatures class sits among the Glen Coe hills. The area is a public hiking zone with access trails, though conditions are weather-dependent, so sturdy footwear and a forecast check are wise. The surrounding Glen Coe scenery is spectacular in its own right.
Loch Shiel, near Glenfinnan in the Highlands, served as the Hogwarts lake and its surrounding grounds. Views of the loch can be had from public roads, and boat tours also operate on the water. Paired with the Glenfinnan Viaduct a short distance away, it makes an easy double stop, and several Highlands day tours from Edinburgh and Glasgow take in both along with Glen Coe in a single loop.
This public park and lake in Surrey provided the lakeside scenes featuring Sirius Black and general lake views. Access is free, and the lake sits on the edge of Windsor Great Park, making it a pleasant half-day trip from London. The tree-lined shores look much as they did on screen, and the park is popular with walkers and families, so it works for visitors mixing Potter stops with a relaxed day out.
Lambeth Bridge is where the Knight Bus squeezes between two double-deckers in one of the film's most famous sequences. The bridge remains fully open to pedestrians with free viewing, and it sits within walking distance of the South Bank, the London Eye and Westminster. It is a low-effort stop that pairs well with a riverside walk through central London's Potter and general sightseeing highlights.
This Watford house provided the exterior of Number 4 Privet Drive, the Dursley family home. It is a private residential address, so viewing is exterior only from the public street, and the same area covers the Knight Bus pickup location on nearby Dowding Way. Visitors travelling between London and the Warner Bros. Studio Tour in Leavesden will find both stops a short detour from that route.
Where It Is Set Versus Where It Was Filmed
The story is set in a fictional version of Britain, with Hogwarts placed in Scotland and the Dursleys on a suburban London street. Filming happened in real places: studio work at Leavesden and Shepperton, plus location shooting in the Scottish Highlands, London, Hertfordshire and Surrey. So while the wizarding world is invented, nearly every exterior seen on screen corresponds to an actual visitable site.
The Studio Side
Most of the film was shot at Warner Bros. Studios Leavesden in Hertfordshire, which is open to the public today as the Warner Bros. Studio Tour London, The Making of Harry Potter. Shepperton Studios in Surrey also hosted production work but is not visitable. For fans planning a trip, the Leavesden studio tour is the single closest experience to standing inside the film's sets, and it pairs naturally with the nearby Watford exterior locations.

Frequently Asked Questions
Where is Hogwarts filmed in Prisoner of Azkaban?
There is no single Hogwarts location. Interiors were built at Warner Bros. Studios Leavesden, exterior grounds scenes used Glen Coe, the lake is Loch Shiel, and a staircase inside St. Paul's Cathedral doubled for a Hogwarts stairwell.
Can you visit the Hogwarts Express bridge?
Yes. The Glenfinnan Viaduct is visible from public viewpoints with parking nearby, and the Jacobite steam train, the same train used in filming, still crosses it on scheduled journeys.
Is Privet Drive a real street you can visit?
The exterior of Number 4 Privet Drive is a real house at 41 Royce Grove in Watford. It is a private residence, so viewing is from the public street only. The Knight Bus pickup scene was filmed on nearby Dowding Way.
Where was the Knight Bus filmed?
The Knight Bus was a real custom-built triple-decker driven through London streets. Scenes were shot at Lambeth Bridge, Green Lanes in Palmers Green, and outside the Leaky Cauldron exterior at 8 Stoney Street by Borough Market.
Can you go inside the studios where the film was made?
Yes. Warner Bros. Studios Leavesden operates the Warner Bros. Studio Tour London, The Making of Harry Potter, which is open to the public. Shepperton Studios, which also hosted production, is not visitable.
What is the best tour for the Scottish locations?
A Highlands day tour from Edinburgh that includes Glenfinnan Viaduct and Glencoe covers the key Scottish sites from this film in one day, including the viaduct, the loch country around Glenfinnan and the Glen Coe hills.
Prisoner of Azkaban is arguably the best film in the series for location hunters, because its Scottish and London exteriors are so accessible. A day or two in London covers the cathedral, market and bridge sites, a short detour to Watford handles Privet Drive alongside the studio tour, and a Highlands day trip delivers the viaduct and Glen Coe scenery that defined the film's look.
