Discover London on a three-hour audio-guided walk. A handy offline app will show the route on a map. You will not only see the city's main attractions, but you'll also get a glimpse of the picturesque landmarks that inspired the Harry Potter movie saga. The tour includes 25 locations, each of them also interesting historic London landmarks. Fascinating audio recordings will replace a live guide. The full route on foot will take three hours. If you wish, you can shorten the walk with a ride on a double-decker bus (ticket not included in the tour price).
