As of March 2026, backpacks are absolutely allowed in all Walt Disney World theme parks, water parks, and Disney Springs, provided they adhere to specific size and safety regulations. Your bag must not exceed 24" long x 15" wide x 18" high (61 cm x 38 cm x 46 cm). Every bag is subject to security screening, which in 2026 primarily uses advanced contactless scanners that allow you to walk through without removing items, though manual searches are still performed if the scanner flags an anomaly. Prohibited items inside bags include loose ice (reusable ice packs are required), dry ice, glass containers (except small baby food jars), and alcoholic beverages. Backpacks are welcome on almost every attraction; you simply place them on the floor of the ride vehicle or in a provided mesh pocket. For high-intensity rides like TRON Lightcycle / Run, free lockers are provided to store your bags during the experience, ensuring a safe and hands-free journey for all guests.
