The location of Hogwarts Castle depends on whether you are visiting Universal Orlando Resort in Florida or Universal Studios Hollywood in California. In Universal Orlando Resort, Hogwarts Castle—which houses the "Harry Potter and the Forbidden Journey" attraction—is located in the Islands of Adventure theme park within the "Hogsmeade" section of The Wizarding World of Harry Potter. Orlando is unique because it also has a second Harry Potter land, "Diagon Alley," located in the adjacent Universal Studios Florida park; the two lands are connected by the Hogwarts Express train, which requires a "Park-to-Park" ticket to ride. In contrast, at Universal Studios Hollywood in California, the entire Wizarding World of Harry Potter (including Hogwarts Castle) is located within the single Universal Studios Hollywood park. While the Hollywood version of Hogsmeade is slightly more compact than its Orlando counterpart, the castle itself is nearly identical in scale and detail. As of 2026, Harry Potter fans should also note that a third major land, based on the British Ministry of Magic and the Fantastic Beasts films, has recently opened at Universal’s newest Orlando park, Epic Universe, making Orlando the definitive destination for the most expansive "Wizarding World" experience globally.
