Yes, The Wizarding World of Harry Potter at Universal Orlando Resort is split across two distinct theme parks: Universal Studios Florida and Universal’s Islands of Adventure. Diagon Alley (which includes the Escape from Gringotts ride and the Leaky Cauldron) is located in Universal Studios Florida. Hogsmeade (home to Hogwarts Castle, Hagrid’s Magical Creatures Motorbike Adventure, and Forbidden Journey) is located in Islands of Adventure. These two lands are physically connected by the Hogwarts Express train. To experience both lands in a single day—and to ride the train—you must have a "Park-to-Park" ticket. In 2026, this "split" remains one of the most successful immersion strategies in theme park history, effectively doubling the experience for fans. Note that in 2025/2026, Universal is also opening a third Potter-themed land, The Ministry of Magic, within the new Epic Universe park, further expanding the "world" into three distinct locations across the resort property.
