Choose the experience before drawing a route
For architectural atmosphere, begin with Leadenhall Market in the City of London. For the familiar trolley photograph, choose King’s Cross station. Neither requires a Warner Bros. Studio Tour ticket, and neither offers the studio’s collection of sets. A filming location, a themed photo installation and a ticketed attraction should not be presented as interchangeable stops.
The map links these two existing AnyMappy Places so you can judge their positions against your hotel and other plans. It does not imply that they form a short, continuous walking circuit. Choose one as the anchor; add the other only if the cross-city transfer fits. Our diagram is a decision aid, not a timed itinerary or a live transport route.
What free means at each stop
The market’s public passages can be visited without an attraction admission ticket. Shops, meals and drinks remain separate purchases. The official London visitor guide lists the market as accessible around the clock, with individual businesses keeping their own hours; an open passage does not guarantee open shops or uninterrupted access during an event.
At King’s Cross, the estate’s visitor information says you may take your own trolley photograph without paying. A professional image and merchandise are optional purchases. The station concourse attraction is not a real departure platform for a Hogwarts train. Leave a queue allowance if the photograph matters, particularly around school holidays; there is no reliable fixed waiting time to promise.
The London Zoo detail that changes the plan
The Zoo’s historical page records the old Reptile House closing to the public in 2023. Its current FAQ places ZooTown, a children’s role-play attraction, inside the former building. The replacement reptile and amphibian habitat is a separate experience nearby. This is why an old list saying simply “visit the Harry Potter snake enclosure” is not enough to plan a current visit.
Treat London Zoo as a separate paid zoo outing, chosen for its present attractions. Check the current venue information before buying a ticket, including any separate session booking. Do not buy admission solely on the assumption that the original film enclosure remains open for a walk-through. We include this warning in the comparison, not as a promised third free stop.
Keep the day flexible and the photograph honest
Start with the stop that answers your main reason for going. If you want the trolley picture, protect that time before making a restaurant or train commitment. If you prefer architecture, allow yourself to explore the market passages and look up at the roof rather than chasing every screen reference. Neither choice needs a guided tour to be meaningful.
Check public-transport options on your travel date instead of relying on an old door-to-door estimate. Rain, luggage and accessibility requirements may make two separate visits more comfortable than one long walk. The photographs here are archival views of the actual places, not current crowd reports; the station image shows the concourse architecture rather than promising a particular trolley setup.
Places in this article
Leadenhall Market
Leadenhall’s covered streets are the choice for someone who wants to recognise a real urban setting rather than enter a recreated film set. London’s official visitor guide connects the market and Bull’s Head Passage with the first film and the Leaky Cauldron entrance. Look at the roof, passages and junctions together: the location makes more sense as a piece of the City than as a single doorway to photograph.
Use the Place pin to orient yourself before exploring, but respect shop entrances and working businesses. A closed shop does not mean the whole public market is closed, just as open passages do not mean every business is trading. This stop works well as the main Potter reference within a wider City visit. The photograph records the market in July 2022 and is not evidence of present-day displays or crowds.

King’s Cross Station
King’s Cross answers a different wish: taking a recognisable Platform 9¾ souvenir photograph. The visitor installation is on the concourse wall, so do not search the real gap between tracks nine and ten. The estate’s official guide distinguishes your free personal photograph from the optional professional service and adjacent shop. Keep that distinction in mind when comparing a free outing with paid photo packages.
Make the station your main stop if you are arriving nearby or if the trolley photograph matters more than architectural film locations. Allow flexibility for the queue and keep access routes clear for passengers. The 2019 photograph shows the western concourse ceiling; it is included to explain the station setting, not to identify the current exact photo-queue position. Consult current station signage and staff when you arrive.

Can I visit these places without a studio ticket?
Yes. Leadenhall’s public passages and the King’s Cross concourse photo stop are separate from the Warner Bros. Studio Tour. Transport and optional purchases still cost money.
Is the Platform 9¾ photo free?
The King’s Cross visitor guide says you can take your own photograph without paying. Professional photographs and shop purchases are optional; waiting times vary.
Can I still visit the original London Zoo Reptile House?
Do not assume it operates as the old reptile display. The Zoo records its closure in 2023 and now describes ZooTown in the former building. Check the current attraction and admission rules.
Is this a short walking route?
No fixed walking circuit is promised. The market and station are in different areas. Choose one anchor and check a current transfer if you want both.
