Enjoy free entry to 78 of Scotland's top attractions with the Historic Scotland Explorer Pass – a flexible sightseeing pass that allows you to visit the sites that interest you most. Make the most of skip-the-line entry to Scottish showstoppers such as Edinburgh Castle and Stirling Castle, and visit lesser-known treasures including Fort George. Choose from a 3-day or 7-day pass and sightsee as you wish; both include a saving of 20 percent on an audio tour at Edinburgh or Stirling Castle as well as an information pack and souvenir passport.
