In 1959 several new rides opened in Tomorrowland. They were the Matterhorn Bobsleds, the Monorail, the Motor Boat ride (no longer there), the rebuilt Autopia and our topic for today the Submarine Voyage. The Submarine Voyage consisted of 8 submarines. Walt Disney boasted at the time the ride opened that he had the 8th largest peace time submarine fleet. The subs were diesel powered boats and for a time women dressed as Mermaids would swim in the water and wave to guest.
For 30 year the ride took voyagers to the depths of the sea. Voyagers saw many creatures of the sea including a sea serpent. Today however after a 10 year break the ride has re-opened as the "Finding Nemo Submarine Voyage" At the attraction's entrance, guests enter the Nautical Exploration and Marine Observation (NEMO) research center. There are three seagulls perched on a nearby buoy, bellowing out the phrase "Mine! Mine! Mine!" every few seconds. Nemo Finders relive the wonderful voyage that Nemo's Dad Marlin had when trying to find Nemo all our friends from the movie are there. Check out the link to see all about it (Way too much to include). No ride through video for this one so nothing is given away! Just a teaser.

By the way: The ride is actually under neath most of Autopia and the Monorail tracks in Tomorrowland.
