Do I need to purchase a separate ticket to view World of Color?
World of Color – Frequently Asked Questions
No. You do not need to purchase a separate ticket to view World of Color. You do need valid theme park admission to Disney California Adventure Park—either a theme park ticket or a Disneyland Resort Annual Passport that is not blocked out on the day you wish to visit.
To access the reserved viewing area in Paradise Park near The Little Mermaid ~ Ariel's Undersea Adventure, you will need either a valid Disney FASTPASS ticket for World of Color or a special voucher that is included in World of Color dining packages.
