Surf's Up! - Santa Cruz Style and it looks like a great big 20 Foot Tall Cresting Wave at Mavericks! Astro Jump's Monster Wave Waterslide is the World's first and favorite Double-Lane Curved Inflatable Waterslide. Riders start high up in the cool misting barrel of the wave then cruise downward, popping over a bump, zipping around a curve then splashing into a pool of whitewater at the base! This waterslide is a ton of fun for both kids and adults. Add an inflatable slip n slide or sno-kone machine to make your party complete!
