The Jungle River Cruise, Jungle River Ride, or River Adventure was to be a river boat ride that would follow an under water track throughout the tropical rivers of Jurassic Park. It followed a track through the Aviary. Visitor's would unload here and proceed to the hotel Pteratops Lodge. However, several unintended problems prevented the ride from opening, such as the Dilophosaurs spitting at the tour boats, Cearadactylus attacking workmen, etc.
