A place of pilgrimage for Harry Potter fans of all ages and a chance to see the sets and props from the movies up close.
The studio is located in Watford (London trains run from Euston), and buses take visitors from Watford Junction station to the venue; booking is essential. Watch rhe incredible film set HERE
The Diagon Alley set constantly changed throughout the film series. Since its construction, walls have shifted, shop fronts have moved and entire buildings have been carefully tweaked.
The Tour is great but not cheap. The budget option is a daytrip (£30 off-peak return from Euston-Watford Junction; £85 tour entry for a family of four). So it’s tempting to go the whole Hogwarts at The Grove – a five-star-home-from-home to Radcliffe, Grint and Watson during the filming years, and now a parkland paradise frequented by actors and footballers. It does package deals including room, breakfast and tickets from £415 per family – and has enough free swimming pools, mountain bike trails, games rooms and Ofsted-rated childcare (£6 an hour) for you to make a weekend of it – and one that all the family will enjoy. The magic of the movies was mostly down to their meticulous realisation of Rowling’s wonky, spectacular world. Here, you begin by entering Hogwarts Great Hall and – about three hours later – finish with a staggering 1:24 scale model of the multi-turreted school and its grounds. Fantastical animatronic beasts, commentary and a world of wizard props including a three-decker purple bus crop up on the way.
