London’s Harry Potter locations work best as two outings: a walk through the City and along the Thames, and a visit to King’s Cross and neighbouring St Pancras. The Warner Bros. Studio Tour at Leavesden deserves a separate plan. This guide groups the stops so you can choose a manageable day and understand what you will find at each place.
Begin the city walk at Leadenhall Market, on Gracechurch Street, EC3V 1LT. Its painted ironwork, glass roof and cobbled passages give you plenty to look at before you find the film connection. Monument and Bank are useful Underground stations for this starting point.
The market appears in Harry Potter and the Philosopher’s Stone as Harry and Hagrid approach the Leaky Cauldron. Look for Bull’s Head Passage, where the doorway used for the pub’s entrance is located. The fictional pub leads towards Diagon Alley in the story; the real passage is part of a working London market.
Walk through the main arcade and look up at the roof before taking photographs in the passage. The market is open daily, while its shops and restaurants keep individual hours. Keep entrances clear and leave yourself room to enjoy the architecture as well as the familiar scene.
Make St Paul’s the next landmark on your map, then head towards Millennium Bridge. This suggested order brings you from the City’s streets to the river and gives the walk a clear direction.
The pedestrian bridge features in the sixth Harry Potter film, when Death Eaters attack it. On your visit, the attraction is the real crossing and its Thames views. Look back towards St Paul’s from the bridge, then continue to the Bankside end if you are following the route towards Borough Market.
You can enjoy the cathedral’s exterior along the way. If you want to visit inside, give that its own place in the day and use the cathedral’s current admission information. A riverside walk and an indoor visit suit different amounts of time.
Follow the riverside towards London Bridge and finish at Borough Market, 8 Southwark Street, SE1 1TL. This is a useful food stop after the film locations. London Bridge station is beside the market, so you can finish the outing here and travel onwards.
Entry to the market is free. Its regular trading days are Tuesday to Sunday, with Monday closed; holiday arrangements can vary. Aim for a trading day if food is part of your plan. The market’s visitor page has the current hours and explains where to find produce traders and street food.
Borough’s public spaces are on one ground level, although surfaces include cobbles and some restaurants occupy several floors. Accessible toilets are available during trading hours. If access or crowds affect your visit, use the market’s information to choose the part of the day that suits you.
Make King’s Cross a separate stop, perhaps on a day when your travel already brings you through the station. The Platform 9¾ trolley display and Harry Potter shop are visitor attractions within the station. Allow time for a photograph queue and keep space for your actual train connection.
Next door, St Pancras has its own film connection. Its exterior appears as Harry and Ron take off in the flying Ford Anglia in Harry Potter and the Chamber of Secrets. Looking at the station frontage adds a second recognisable location to this part of the outing.
For original sets, props and costumes, plan the Warner Bros. Studio Tour London separately. Its address is Studio Tour Drive, Leavesden, WD25 7LR. Use that address when arranging transport, even though London appears in the attraction’s name.
The official directions name Watford Junction as the nearest railway station and describe services from London Euston. A shuttle connects Watford Junction with the studio and is included in the entry ticket. Arrange your admission first, then plan the outward journey and return around it.
For a short visit, choose either the city walk or the two neighbouring stations. Use TfL’s journey planner for travel between areas, and its accessibility information if you need a route avoiding stairs. Leave room for food, weather and the pace of your group.
