Two Separate Trips: The City Locations and the Studio Sets
Featured Question
Where are the Harry Potter locations in London?
Almost all the London filming locations are free to visit: Platform 9¾ at King's Cross, Leadenhall Market, Borough Market, the Millennium Bridge and Australia House. Most interiors were filmed at the studios in Leavesden, around 20 miles from central London; the Warner Bros. Studio Tour opens those sets to visitors and requires advance timed tickets.
The Harry Potter experience in London is really two different trips, and conflating them causes planning errors. The first is the real filming locations across the city — mostly free, walkable in a day. The second is the Warner Bros. Studio Tour at Leavesden — outside the centre, ticketed, and deserving of its own day. This guide covers both in order.
Quick Answer: The city stops: King's Cross (the Platform 9¾ photo spot and shop — free), Leadenhall Market (the passage leading to Diagon Alley in the first film; the blue door in Bull's Head Passage is in reality an optician), Borough Market (the Leaky Cauldron entrance in the third film), the Millennium Bridge, Australia House (the Gringotts interior — viewable from outside), Claremont Square and the House of MinaLima. *Harry Potter and the Cursed Child* also runs in the West End. The Warner Bros. Studio Tour sits at Leavesden, around 20 miles from central London; the average visit runs 3-4 hours and tickets are timed and must be booked in advance.

The City Route: Walkable in a Day
The direct answer: the locations fall into three clusters, and the sensible order is:
1. The City and Southwark cluster
- Leadenhall Market: a Victorian covered market designed by Sir Horace Jones in 1881, used for the passage to Diagon Alley in the first film. The blue door at 42 Bull's Head Passage is in real life an optician's, and the original meat hooks still sit above the shops.
- Borough Market: the section used as the Leaky Cauldron entrance in the third film — and one of London's best food markets, making it the natural lunch stop.
- The Millennium Bridge: the footbridge destroyed in the sixth film; a free crossing between Tate Modern and St Paul's.
2. The West End cluster
- Australia House (Strand): where the Gringotts interiors were filmed. It is a working embassy, so there is no public access; view it from outside.
- House of MinaLima: the gallery and shop of the studio behind the films' graphic design.
- The Palace Theatre: home of *Harry Potter and the Cursed Child*.
3. The King's Cross cluster
- Platform 9¾: the photo spot inside the station, with the trolley disappearing into the wall and the sign above. Free, though queues form; the adjoining shop opens Monday to Saturday 8am-10pm and Sunday 9am-8pm.
- St Pancras: the neo-Gothic façade next door stood in for King's Cross in some scenes.
- Claremont Square: a street location used in the films — an ordinary London square, and quiet as a result.
A fourth stop — London Zoo: the reptile house scene in the first film was shot here. It sits off the walking route and is ticketed; consider it within a family programme instead.
The Warner Bros. Studio Tour: Its Own Day
The direct answer: the studio tour is at Leavesden, around 20 miles from central London, displaying the actual film sets permanently — the Great Hall, Diagon Alley, the Forbidden Forest, Gringotts, Ollivander's wand shop, the Hogwarts Express and the studio-built section of Platform 9¾. The average visit runs 3-4 hours.
Tickets and getting there: tickets are timed and must be booked in advance; in busy periods they sell out weeks ahead. Two routes: train from London to Watford Junction plus a shuttle bus, or direct coaches from central London points such as Victoria and Baker Street. With travel included, the day runs longer than half a day — give it its own slot.
The 2026 seasonal features:
- Feature: First Year at Hogwarts · Dates: 7 May – 7 September 2026 · What's included: The first film's 25th anniversary; original props and sets, the Great Hall dressed for the House Cup, a "Secrets of Sound Effects" show
- Feature: Dark Arts · Dates: 16 September – 8 November 2026 · What's included: Eerie lighting, floating pumpkins in the Great Hall, Dementors in the Forbidden Forest
- Feature: Hogwarts in the Snow · Dates: 14 November 2026 – 17 January 2027 · What's included: Sets dressed for winter; Christmas trees in the Great Hall, snow on the castle model
These are included in the standard ticket and may well decide your visiting date — Hogwarts in the Snow in particular is the year's most in-demand period.
Optivest Note: Among the families we advise, two mistakes recur with this tour. First, booking late: visitors who plan to buy "once we're in London" mostly cannot get the date they want, and even three weeks out the options can be thin. Second, squeezing the tour into a city day — travel plus the tour consumes most of the day, and adding another central attraction does not work. The practical rule: book the moment your dates are fixed, and put nothing else on that day.
Budget: Free Route vs Full Programme
- Item: City filming locations (Leadenhall, Borough, Millennium Bridge, King's Cross, Australia House) · Cost: Free
- Item: Platform 9¾ photograph · Cost: Free (professional photos charged)
- Item: Guided walking tours · Cost: Paid (children free on some tours)
- Item: Warner Bros. Studio Tour · Cost: Paid, from £56 (2026)
- Item: Cursed Child at the Palace Theatre · Cost: Paid, varies by seat
On a tight budget: the city route alone fills a day and costs almost nothing. The studio tour is not essential to the experience, but it is the part that delivers most for genuine fans of the series.

Frequently Asked Questions
How far ahead should I book the Studio Tour?
As early as possible — the moment your dates are fixed. In peak periods (summer, school holidays, the Hogwarts in the Snow season) it sells out weeks ahead, and even three weeks out the time slots can be limited.
How long does the Studio Tour take?
The average visit is 3-4 hours. Adding return travel from central London makes it longer than half a day, so plan it as a separate day.
Is Platform 9¾ free?
Yes, the photo spot is free to visit and you can pose with the trolley. Professional photography is charged. The adjoining shop is free to browse.
Is it suitable for young children?
The Studio Tour runs long enough that very young children can lose interest; it lands best with children over eight who know the series. The city route suits all ages and allows breaks.
How long does the city route take?
Covering the three clusters — City-Southwark, West End, King's Cross — at a comfortable pace with lunch fills a full day. Compressed, the main stops (Leadenhall, Millennium Bridge, King's Cross) fit into half a day.
Do I need a guided tour?
Not to find the locations — all are public and mapped. A guide adds filming detail and storytelling, which helps hold children's attention. Some tours include under-16s free.
Conclusion
Divided correctly, a Harry Potter trip in London is both cheap and satisfying: the city route costs almost nothing and fills a day, while the studio tour is a separate experience that earns its own. The one critical decision is when you book.
