The fun-shine starts here — at our 65,000 square foot indoor Lost Paradise Waterpark. There’s no need to worry about cold, rain, or snow as it’s always a balmy 84 degrees here and the sun shines endlessly, so don't forget to pack your swimwear because you're definitely going to want to get wet!
The atmosphere of our indoor Waterpark just north of Chicago has been inspired by the Florida Keys and you’ll appreciate the thoughtful little touches including bright tropical colors, and a laid-back ambiance. Don’t let that fool you — we’re intensely focused on ensuring that each and every guest has the ultimate waterpark experience. We pay close attention to detail to ensure that every moment here is a perfect one for our guests.
There’s plenty of water thrills and fun for kids of all ages here. We’ve got Wild Rides which are guaranteed to get your pulse pounding, lazy floats down the river for those who are looking forward to Takin’ it Easy, and a play pond kiddie pool for the Lil’ Limers who need some extra special attention in a fun, safe and secure environment.
Most important of all, you can rest assured that your family will be enjoying a monitored, safe atmosphere. Our friendly, attentive, highly trained lifeguards are always on duty to give you peace of mind. And while the lifeguards keep watch over our guests, our waterpark technicians oversee all 420,120 gallons of water flowing through the park to ensure it's the cleanest in the waterpark industry. Our state-of-the-art Ozone technology is an environmentally safe, eco-friendly sanitation process. It is 3,000 times faster at oxidation and 200 times stronger than chlorine, yet has no effect on skin or hair. Ozone kills 99.9% of bacteria viruses and other harmful contaminants on contact. You can feel confident that KeyLime Cove is the best choice for your waterpark getaway.
