For the safety of our guests, certain rides have height requirements: Due to a change in slide manufacturer requirements, Pipeline Mines now has a 42 inch in bare feet height restriction. 42 inches in bare feet for Mammoth Canyon Family Raft Ride, Rattlesnake Rapids and Double Trouble. 48 inches in bare feet for Thunder Falls, Viper's Vortex and the Avalanche. There are many other rides for our smaller guests to enjoy, including Little Splash Mountain kiddie play area, with Kiddie Kowabunga tube slide (48" maximum height). If your child is close to 42" in bare feet or 48" in bare feet please go to Guest Relations and ask to have them measured at Roaring Springs official Height Measurement Station. They will receive a wristband indicating which slides they're tall enough to ride if they meet the height requirement in bare feet.
