Jurassic Park: The Ride (Jurassic Park River Adventure at Islands of Adventure) is a water-based amusement ride that is based on the Steven Spielberg film Jurassic Park and Michael Crichtons novel located at Universal Studios Hollywood. The ride was actually researched and built while the film was still in its production phase. It opened on June 21, 1996. Duplicates of the ride have since been built at Islands of Adventure and Universal Studios Japan. A river rapids ride version of the attraction opened at Universal Studios Singapore in 2010.\r

Among the guests in attendance at the rides grand opening celebration in 1996 were film cast members Jeff Goldblum, Ariana Richards, and Joseph Mazzello. Steven Spielberg also attended the opening, but requested that he be let off of the attraction before the 84-foot (26 m) drop.\r

The ride starts at Ultrasaur Lagoon, where two Ultrasaurus are seen eating plants in the water as well as two Psittacosaurus. The boat then moves behind a waterfall and emerges in Stegosaur Springs, where riders then see an adult Stegosaurus and its young. Two Compys are seen fighting over an empty popcorn box before the boat enters Hadrosaur Cove, where a parasaurolophus pops up in front of the raft. The Jurassic Park Animal Control calls, revealing that the parasaurolophus threw the raft off course, causing it to enter the raptor containment area, which is shown to be heavily damaged.\r

Riders next encounter what appears to be an abandoned tour raft, where a Dilophosaurus is seen eating the remains of a poncho. A nearby motorboat is also abandoned, sent by Jurassic Park Animal Control to guide the raft towards a safe area, but the Dilophosaurus appears to have killed the tourists and boat crew. As of 2014, a Mickey Mouse hat can be seen floating in the water next to the ruined raft as an apparent reference to nearby theme park rival Disneyland.\r

Dilophosauruses jump out and spit their toxic venom (water) at guests. Sparks and flood lights are added to the effect during nighttime operations of the attraction.\r
The raft then enters the Environmental Systems Building (this area at Universal Studios Hollywood has special effects that the other versions of the ride dont). and slowly begins to ascend a long lift hill. A voice on a loudspeaker in the building alerts guests that an emergency evacuation is going to be attempted. As the raft makes its way up the lift hill, numerous alarms are heard as escaped Velociraptors lunge out at guests. Once the raft reaches the top of the lift hill, it drops down a small waterfall and is attacked by a Tyrannosaurus. A claw falls from the ceiling followed by its head and a set of collapsing pipes above riders heads.\r
\r
A technician begins counting down when the buildings life support systems will terminate (due to toxic gases released during the Tyrannosaurus encounter). The raft climbs a small lift hill that brings it closer to the emergency evacuation drop. A second technician screams If you can hear my voice, get out of there! Its in the building! ITS IN THE BUILDING!.\r
\r
The Tyrannosaurus then emerges from a waterfall coming from broken pipes in front of the raft, and lunges down to grab the raft and the raft escapes by plunging down an 85 feet (26 m) high evacuation drop and into a tropical lagoon outside the Environmental Systems Building. A Dilophosaur tries to squirt venom at the passengers one last time. A can of Barbasol can be seen in the planter just before the ride ends, referencing the can Dennis Nedry uses in the first film to steal dinosaur genetics. The raft finally makes its way to the unloading dock where guests disembark the ride through the Jurassic Outfitters gift shop.
