Submarine Voyage (1959–1998) – DLR

The Submarine Voyage (1959–1998) was a splashy Tomorrowland staple at Disneyland, plunging guests into an underwater adventure aboard real submarines to explore a lagoon filled with marine life, mermaids, and the lost city of Atlantis. The subs never fully submerged—they rode on tracks just 8 feet underwater—but clever porthole views and bubbles tricked guests into feeling deep-sea-bound.
