If you're a Harry Potter fan, a tour of the Warner Brothers Studio Tour London is an absolute must. If you're thinking about going, these are the things you'll want to know about the experience.

Where is it? The Warner Brothers Studio Tour London is located in Watford, just north of London and not too far from Heathrow Airport or central London.

When can I visit? You can visit Monday - Friday. Some Saturdays may be available depending on availability and demand. Tours commence every 15 minutes, and each last 90 minutes (approx 3 hours) 

How much does it cost? Tickets start at £32 per person, which includes VAT making it £38 per ticket.

How do I buy tickets or tour? Tickets can be purchased online or by phone (tickets are unavailable at the site itself).

What does a ticket get me? A ticket gets you access to the whole tour and all areas and activities, 3D glasses for use in the 3D tour (and if you want to keep them) as well as a commemorative souvenir programme and lanyard, a map of the studio showing how it all fits together, entrance into two of the soundstages, access to part of the outdoor filming areas as well as an audio guide to accompany you on your journey through this fantastic site.

What should I wear? You can wear brown shoes and clothes as long as you are comfortable with them. Alternatively, you can get a pair of black dress shoes at the studio for £6. Prices vary for other items such as a cloak, scarf, or hat.

Can I take my camera? Yes, however, you will need to ask before use so that those exercising the right of photographic activities on the site can be granted access. Those wearing a camera are asked to wear a lens cap and strap.

Can we go outside? Yes, the weather is always great in Watford, and you can see wandering around the studio grounds after your tour.

Is there anything else I need to know? For children aged 4-11 years old, it's suggested they wear thin layers as they will get freezing during the tour. No hot drinks are served on the site, but there is a cafe nearby if you want to stock up on something. The whole tour takes approximately 3 hours, so if you're planning on being back by 1:30 pm, it's not too bad to be back either in time for an afternoon tea (Tickets for this are not included in the step-on price).
