Ghostbusters- Hook and Ladder 8: Visit the headquarters of your favorite parapsychologists, the Ghostbusters, in downtown Manhattan. While I doubt you'll find Slimer here, the building does house actual firefighters.
Star Wars- Endor: Grab your light saber and journey to the Redwood National Forest and State Parks in California. The Tall Trees Redwood Grove was used to shoot the Ewok’s stronghold in Return of the Jedi. Bonus venture- parts of the State Park were used to film scenes from The Lost World, the Jurassic Park sequel. (Want to visit the Star Wars rebel base on the fourth moon of Yavin? Then journey to the Mayan temple ruins in the Tikal National Park in Guatemala.)
Harry Potter- Hogwarts School of Witchcraft and Wizardry: Hogwarts Castle was actually filmed all across England. "Christ Church College and Cathedral in Oxford was used for its 16th-century stone staircase, and the design of its dining hall inspired Hogwarts' Great Hall; Gloucester Cathedral was used for the school's hallways in the first two films; Lacock Abbey near Chippenham in Wiltshire was used for a number of Hogwarts’ classrooms; and Bodleian Library of Oxford University, Fourth Form Room of Harrow Old Schools in Greater London, and Alnwick Castle in Northumberland were all locations used to bring Hogwarts alive on the big screen." (Mental Floss)
X-men- Xavier's School for Gifted Youngsters: Head back to school and visit Hatley Castle in British Columbia, Canada. The exterior of this castle was used for the school in Generation X, X-Men, X2: X-Men United, and X-Men: The Last Stand.
Indiana Jones and the Last Crusade: Seek the holy grail when you travel to Al Khazeneh temple in Petra, Jordan. This temple served as the location of the Holy Grail in the third Indiana Jones film.
Greystone Mansion- Spider Man, Iron Man, and more: Another famous set that has appeared in over 100 films. Some of the roster's more nerdy side includes movies such as Iron Man, Spider Man, X-men, Batman & Robin, and Ghostbusters II.
