Mammoth opens as the world's longest water coaster
Background
Mammoth opened on May 11, 2012 as a Guinness-recognized longest water coaster — 1,763 feet of ProSlide HydroMAGNETIC track with six LIM boosts, seven drops totaling about 187 feet, and a three-minute family soak across more than three acres.
It later claimed Amusement Today's Golden Ticket for Best Water Park Ride (2023), succeeding Wildebeest after that ride's long run atop the ranking. Together the two HydroMAGNETIC coasters define Splashin' Safari's adult thrill skyline.
