The adventure begins in an expedition storehouse where video monitors broadcast news bulletins reporting that a mysterious subterranean cavern has been discovered at Water World.  Authorities report that the passageway may lead to the center of the earth, where prehistoric creatures may still exist. The journey begins as two to five-person tube boats disappear into the howling winds of a bat cave. From there, they travel through lakes, caverns, swamps and narrow canyons.  Realistic rockwork, prehistoric plants and creatures surround the adventurers: Duckbilled dinosaurs watch you; ancient turtles chew on strange vegetation; large flying reptiles–Quetzalcoatlus–are perched ready to swoop down on unsuspecting riders.  The huge sea monster, Elasmorsaurus, swings out from his lair above the waterway, chomping his sharp teeth, and rounding a bend in the river, visitors come face to face with a huge T-Rex, looming twelve feet over their heads, roaring and gnashing his jaws. The ride was produced in cooperation with R & R Creative Amusement Designs, Inc. of Anaheim, California. Multiple special effects, multiple sound and lighting effects and the realistic animatronic creatures…coming at you, in front of, above, around you…makes the voyage a multi-sensory experience.
