The Submarine Voyage was an attraction at Disneyland in Anaheim, California. The attraction features vehicles designed to resemble submarines. It first opened on June 14, 1959, as one of the first rides to require an E ticket. It was part of a major expansion of Tomorrowland, which included the Matterhorn Bobsleds roller coaster, an expanded version of Autopia, the Disneyland Monorail, and the Motor Boat Cruise. The Submarine Voyage closed on September 8, 1998; at that time, it was reported that the attraction would reopen with a new theme by 2003, but that did not occur. The attraction ultimately reopened in June 2007 themed to Disney and Pixar's Finding Nemo, and now operates as Finding Nemo Submarine Voyage.
