Because it penetrates the very heart of Edinburgh’s UNESCO World Heritage-listed Old Town and is home to so many of the city’s star attractions, including St Giles’ Cathedral, the Scotch Whisky Experience, and Camera Obscura, the Royal Mile is a staple on Edinburgh sightseeing tours. Classic walking tours, Harry Potter–themed tours, and tours of the underground Real Mary King’s Close all cover portions of the Royal Mile, as do hop-on hop-off and ghost bus tours. Visitors based in Glasgow can take day tours to the city to see Edinburgh’s biggest attractions, among them, of course, the Royal Mile.
