MAMMOTH water ride

Ride experience

Friends and family climb aboard a 4 or 6-person raft to share an unforgettable adventure face to face.

Rafts rocket through the winding MAMMOTH channels, a breathtaking series of back-to-back curves, drops and vortex loops. The wide, sweeping flumes and compounded curves are engineered to position the raft high on the walls, injecting plenty of hang time on the steep banks.

At ProSlide, we engineer a ride experience that’s the most fun in perfect safety. Our multi-radius compound curves create high excitement in maximum comfort. Every raft, no matter how full, has the same smooth and thrilling ride, whether hugging the wall or shooting out of a turn like a slingshot.

Exclusive technology

Our invention of MAMMOTH group rafting rides in the 90’s took the industry to new levels: we doubled the width of our ride flumes and tripled their height! For the first time, large groups could share the thrills and chills of a big water slide face-to-face. Still the design leader, ProSlide’s many innovations maximize fun, safety and capacity.

  • Twin-entry start tub loading helps deliver incredible ride capacities of ~1,200 or more per hour.
  • Rides designed with clear sight lines means safe and steady dispatch with minimal staff.

Classic water ride

The MAMMOTH is the best-selling family rafting ride in the world. This classic water ride and consistent performer rounds out the guest experience and provides maximum value for your budget.

Winner of multiple Best Water Ride awards, MAMMOTH water rides are one of the building blocks of a successful and one-of-a-kind water park. We customize them to fit your unique space and site challenges without losing an ounce of fun. Each MAMMOTH is a custom water slide that

  • Maximizes topography
  • Fits into available spaces
  • Delivers the right thrill level
  • Reduces costs

The MAMMOTH is also available in a high-speed TurboMAMMOTH version that drops rafts – at steeper grades – through a series of accelerating bumps.
