Experience a lovely cruise down a Costa Rican river to an experimental dinosaur refuge. But beware—rafts have been “going off course” and venturing into the backstage holding pens where the most dangerous dinosaurs are on the loose, including a 50-foot-tall T. Rex. Like Disneyland’s Splash Mountain, this flume ride is gentle until you get to the big 84-foot drop at the end. Expect to get a bit wet—you may want to wear a poncho to avoid the splashes (a nearby vending machine sells them for $6). The best seats are in the front. Watch for the Mickey ears! 42"/107 cm. height restriction. Health and motion sickness warning. Transfer from wheelchair/ECV to ride. Child switch available.
