Runoff Rapids are 3 different inner tube waterslides for big kids, teens and adults at Disney's Blizzard Beach Water Park. Grab an inner tube and careen down Mount Gushmore on any of the three unique waterslides. Each flume is different, so try them all! The centre slide is fully enclosed and accommodates one rider at a time. The two outer slides can accommodate rafts that hold up to 2 people. All 3 waterslides at Runoff Rapids twist and turn down the hill, taking you on an invigorating ride with a plunge into the pool at the bottom. Dive in! To get to Runoff Rapids follow the signs for this attraction at the Red Slope area of the mountain.
