Watford has become an especially popular choice with tourists over the last decade or so, and perhaps not least because of the Harry Potter Warner Brothers Studio tour setting up here. This English town that lies northwest of London has plenty to offer, but like most we love that it has the wizarding world at its heart in this impressive studio space. You'll be able to see costumes and sets from the Harry Potter film series, along with Diagon Alley, the wizard's shopping street, the Knight Bus and even grab a pint of Butterbeer. If you're not a fan of J.K Rowling's book and film series, though, you'll find plenty of other things to do in Watford such as a visit to the theatre, Tudor houses and gardens, Vicarage Road, Sports Stadium and a stroll through Cassiobury Park.
