Yes, you are absolutely allowed to bring backpacks into Disneyland Paris in 2026, provided they meet the park's safety and size guidelines. Standard backpacks must not exceed the dimensions of 55cm x 40cm x 25cm (roughly 21 x 15 x 9 inches). Every bag must pass through a security X-ray machine and a manual inspection at the park entrance. While you can bring your backpack on almost every ride—usually placing it at your feet or in a dedicated net—very large trekking packs may be cumbersome and are better left in the Guest Storage (Consigne) lockers located near the entrance for a small daily fee (€10–€15). It is important to note that while the bag itself is fine, certain contents are banned: glass containers (except small baby food jars), alcohol, and "selfie sticks" that do not fold down completely. Most 2026 visitors opt for a lightweight, water-resistant daypack to carry essentials like rain ponchos, portable chargers, and snacks.
