Alnwick Castle & Gardens

The Borders has more than its fair share of Dukes; this time, the Duke of Northumberland's home, Alnwick. Harry Potter fans, this is it! The location of Hogwarts School and many a quidditch championship. I often imagine the cast of the films having a great time exploring the water gardens, the poisons garden, and the treehouse. Need a spell to get up there? "Wingardium leviosa," as Hermione Granger might say. (58.9 miles)
