Steeped in Celtic and medieval history—and fondly nicknamed Auld Reekie—Edinburgh is a UNESCO World Heritage–listed city widely considered the prettiest in Scotland. Edinburgh Castle’s mighty fortifications dominate the skyline, while the Royal Mile sweeps through the old town to the city below. From the annual Royal Edinburgh Military Tattoo to the Edinburgh Fringe, the city hosts a stellar selection of festivals and celebrations that draw crowds from all over. No visit to Edinburgh is complete without a taster of Scotch whisky, and if you’re looking for a change from the city streets, the soaring peaks of the Scottish Highlands are never far away.
