Almost everything in California Adventure is accessible, but riders have to transfer from their wheelchairs into the ride itself. At Monsters, Inc., Sun Wheel, and King Triton's Carousel, electric convenience vehicle riders transfer to a wheelchair. All shows and other attractions are fully accessible.
Most rides and attractions that have an audio component offer closed captioning, Assistive-Listening devices, and/or reflective captioning. You can find out which ones offer which assistance by looking at the codes on the California Adventure map brochure, and you can pick up Assistive-Listening devices at Guest Services.
