Studio tours in Europe: walk the actual film sets

Two of the most in-demand tickets in Europe aren't theme parks at all. The Warner Bros. Studio Tour London in Leavesden preserves the genuine Harry Potter sets — the Great Hall, Diagon Alley, the Hogwarts Express — while the Game of Thrones Studio Tour at Linen Mill Studios in Northern Ireland does the same for Westeros.

Both are strictly timed-entry and routinely sell out weeks ahead, which changes how you plan: the booking date matters more than the ticket price. The guides below cover realistic booking windows, how long each tour takes, and how to get to the studios from London and Belfast.
