Hi there, Amber! Thanks for bringing your question to planDisney. A warm welcome to you!
Amber, you are allowed to bring a backpack into the parks. The security team will check it prior to entering. A standard sized backpack will be able to fit with you on most attractions. Some attractions have a hook you can use for your backpack. On some attractions you’ll need to keep your backpack securely at your feet. There is a small pouch on some attractions to store a smaller bag.
You can find a comprehensive list of
permitted items on the Disneyland website
here.
I like to bring a small backpack with me to the parks. In my backpack you’ll find:
~ a mobile phone charger
~ a reusable water bottle (I like to use the refilling stations instead of buying bottled water)
~ sunscreen
~ a hat
~ a few munchies
~ a small first aid kit
~ hand sanitizer and hand wipes
~ a light jacket for the evening
~ some room to spare for a Disney souvenir!
I hope you have a magical visit, Amber!
