In terms of total acreage, Disneyland Park is larger than Disney California Adventure (DCA). Disneyland Park, the original theme park opened by Walt Disney in 1955, encompasses approximately 85 acres. In contrast, Disney California Adventure, which opened in 2001 on the site of the original Disneyland parking lot, covers about 72 acres. While the 13-acre difference may seem small, Disneyland Park's layout is much more densely packed with attractions, featuring nearly double the number of rides compared to DCA. Disneyland Park is divided into nine themed lands, including the massive 14-acre Star Wars: Galaxy's Edge, which significantly bolstered its size in recent years. DCA's footprint includes the sprawling Cars Land and the Avengers Campus, but it generally feels more open and has fewer physical "rides" than its older sibling. For a traveler in 2026, it is worth noting that while Disneyland is the "bigger" park by area and ride count, DCA often feels equally substantial due to its larger-scale show venues like the World of Color lagoon and more spread-out walking paths.
