The route runs 676 meters (2,218 ft) between Hogsmeade station in the Islands of Adventure theme park and King's Cross station in the London area of the Universal Studios Florida theme park. It provides a connection between the Diagon Alley and Hogsmeade areas which, together, form The Wizarding World of Harry Potter, based on the Harry Potter film series.

Universal Orlando Resort, often shortened to Universal Orlando, is a 541-acre (219 ha) theme park and entertainment resort complex located in Orlando, Florida. Following the opening of Universal Studios Florida in 1990, NBCUniversal moved forward with plans to expand from a single park into a large resort hoping to compete with Walt Disney World. In 1999, a second theme park called Islands of Adventure opened in addition to CityWalk, a shopping promenade and nightlife district that incorporates a variety of themed hotels, restaurants, and retail outlets. A third 30-acre (12 ha) water theme park, Volcano Bay, was added in 2017, and a fourth upcoming theme park, Epic Universe, is scheduled to open in 2025.
