Which land is the first guests enter at Disneyland?

The first land guests enter at Disneyland is Main Street, U.S.A., the themed avenue immediately inside the park's main entrance.

Main Street is designed as an idealized American town from the late 19th and early 20th centuries. Its appearance draws heavily on Walt Disney's hometown of Marceline, Missouri, as well as Fort Collins, Colorado, which designer Harper Goff used as a visual reference. Walt also admired places such as Henry Ford's Greenfield Village, whose historic streets and transportation helped shape the concept.

Guests typically arrive at Town Square after passing through the entrance station, then travel along Main Street toward Sleeping Beauty Castle and the Central Plaza, commonly called the Hub. From there, paths lead to lands including Fantasyland, Adventureland, Frontierland, and Tomorrowland. Main Street is therefore the entrance land, not Fantasyland, even though Fantasyland begins beyond the castle. Its shops, restaurants, vehicles, cinema, and firehouse create a welcoming transition from the real world into Disneyland's imagined environments.
