No, you cannot bring a collapsible wagon into Disneyland or Disney California Adventure. According to Disney’s official 2026 property rules, all wagons and stroller wagons—whether they are pushed or pulled—are strictly prohibited inside the theme parks. This includes popular "stroller wagon" hybrids. The policy is designed to ease guest flow and reduce congestion in high-traffic areas. Additionally, standard strollers must be no larger than 31 inches (79 cm) wide and 52 inches (132 cm) long. If you arrive with a wagon, you will be asked to return it to your vehicle or hotel. For those who need a replacement, Disneyland offers stroller rentals near the main entrance. The only exception to this rule is for guests who require a wagon as a medical necessity; in such cases, you must visit Guest Relations to have your wagon screened and tagged as a "stroller as a wheelchair" before entering the parks.
