Highclere Castle, the impressive mansion used as the setting for the popular Masterpiece Theater series "Downton Abbey," has been open to the public for several years. But interest in the castle -- completed in 1878 and the familial estate of the Earl and Countess of Carnarvon -- has skyrocketed since the fall of 2010, when the acclaimed TV show began airing, first in the UK.
If you travel to the estate, about 60 miles west of London, you can visit the castle and grounds on your own for 9.50 pounds (about $15). There's an extra fee to see an exhibit on Egypt centered on the fifth Earl of Carnarvon, who helped discover the tomb of King Tut in 1922.
Or you can take a luxury coach from London with Brit Movie Tours, which broadcasts episodes from "Downton Abbey" on the trip out.
What you see: The coach tour takes you to Bampton in Oxfordshire (Downton Village) and Highclere Castle and its grounds.
Tour frequency: Mondays
Cost (per adult): 79 pounds (about $125) for nine-hour tour
