Details: Edinburgh Guided Sightseeing Tour
Edinburgh Castle, the historical and emotional heart of the city, is just one of the many sights you will see on this tour, led by a licensed professional guide. Make your way along the Royal Mile, the main thoroughfare of the 16th and 17th centuries. (It's actually one mile and 107 yards long--from Edinburgh Castle to the Palace of Holyrood House). As you make your way along cobbled streets, you'll see a handful of the several thousand buildings officially protected in Edinburgh because of their architectural or historic importance. The 200-foot spire of the Sir Walter Scott monument soars above the East Princes Street Gardens. Grand figures from Scottish history adorn its heights, make sure you also look down -- the figure below the marble statue is Scott's favorite dog, Maida.
