20,000 Leagues Under the Sea: Submarine Voyage was one of the most ambitious and fondly remembered attractions in the early history of Magic Kingdom. Located in Fantasyland, the attraction invited guests to board one of 12 riveted submarines modeled after Captain Nemo’s Nautilus from Disney’s 1954 live-action adaptation of Jules Verne’s classic novel. Although it was not ready for Magic Kingdom’s opening day, the attraction debuted shortly afterward on October 14, 1971, and quickly became one of the park’s most popular experiences.
Guests descended into the narrow interior of a Nautilus-style vessel and sat on fold-down seats facing individual portholes. The ride vehicles were not true submarines: much of each craft remained above the waterline while the passenger compartment sat low enough to create the sensation of traveling beneath the surface. Bubble effects, waterfalls, dim lighting, and Captain Nemo’s narration strengthened the illusion as the crew received the command to “Dive! Dive!”
The voyage began in a sprawling outdoor lagoon filled with coral, kelp beds, giant clams, turtles, fish, and deep-sea divers. After passing into a concealed show building, the tone became darker and more mysterious. Riders encountered the Graveyard of Lost Ships, sharks circling sunken vessels, the underside of the polar ice cap, strange creatures from the ocean depths, and the submerged ruins of Atlantis. The attraction also included a sea serpent, mermaids, and a dramatic finale in which a giant squid attacked another submarine before turning its tentacles toward the guests’ own vessel.
20,000 Leagues Under the Sea closed on September 5, 1994, after nearly 23 years of operation. Its lagoon remained visible in Fantasyland for another decade before demolition began in 2004. Portions of the site were later occupied by Pooh’s Playful Spot, which operated from 2005 to 2010, and then incorporated into the New Fantasyland expansion. Seven Dwarfs Mine Train and Under the Sea – Journey of the Little Mermaid now occupy areas once associated with the former lagoon.
Today, the attraction remains a major symbol of lost Walt Disney World history. Its scale, distinctive Nautilus vehicles, and unusually immersive atmosphere have given it an enduring reputation among longtime fans. Subtle tributes can still be found around Fantasyland, while the Disney Treasure cruise ship’s Periscope Pub draws inspiration from both the original film and the former Magic Kingdom attraction.
