Iowa's Largest Water Park! Located in Waterloo, Lost Island Waterpark has extreme water slides and attractions. Breathtaking drops, dizzying speeds and pitch ..


Our newest addition, this ride works a lot like a roller coaster. Guests will experience climbs, drops, twists, turns and everything in between! With only ten of its kind in the WORLD, this water coaster is sure to make your visit a memorable one!

A thrilling twist on the standard race slide. Riders start in an enclosed flume, gaining speed before exiting onto the open racer lanes. 4 lanes to race. Steep rolls and drops to provide maximum ride excitement.

The Molokini Crater is a massive water thrill ride, resembling a 60-foot funnel. Guests board a 4-person, cloverleaf-shaped raft 75 feet in the air. Shoot down a long tunnel, spinning back and forth, side to side, before dumping into the 60-foot diameter funnel! Finally, glide through a waterfall and splash down in the pool below!

The Calypso Cascade sports a huge, family sized raft that accommodates up to five! Launch off through waterfalls and rushing rapids! Fast turns and high banks make this a crowd favorite!

Accelerate down this steep-pitched, enclosed slide, riding a single or double inner tube, then blast into a 45 foot diameter bowl! Swirl around and around until you're flushed down a center chute into the splash pool below!

COOL TIP! Check out the Tangerine Tempest observation deck to see and hear the excitement of your friends and family as they swirl around and around the giant tangerine striped bowl!
