“Very clean, but not too exciting...”
Reviewed October 12, 2010

.... except for the giant "toilet bowl flush" ride. What a rush! We were four good sized adults in a 4 person tube. It felt like we were going to shoot off the planet.
Have to say, a great place for kids, lots of small kid activity with consistent and attentive life guards. If I lived close with teens I would invest in a season pass.

“Great waterpark! Pricey though”
Reviewed August 17, 2010

We go here about every year, and it is fun! The new watercoaster is FUN!!!! the only thing is, it's really pricey for just 4 people (100 dollars just to get IN) but you can stay as long as you want. but before you go, the orange toilet bowl ride has had a lot injuries on it, where people fall out of their tube. Also, the blue and white funnel hurts your behind, so keep your tush up. But it is VERY fun!!

“Fun & easy to navigate”
Reviewed July 27, 2010

Every summer we take the kids (now 9, 11 & 14) to the Lost Island at least once, usually 2 or 3 times. For the size of the waterpark, the tickets are a tad expensive. Admission is $24 per person. For a family of 5, tickets plus food and refreshments adds up fast! We most recently visited the park on 7/18/10. It seems every year they add a new attraction and this year did not disappoint. There is now a water coaster, like a roller coaster, but in a tube! Being a brand new ride, I think the line was probably abnormally long so we didn't ride it as much as we'd of liked to, but on the other hand the lines for other slides were much shorter than we'd seen in previous visits so it all worked out.
The smaller size of the waterpark makes it easy to navigate and keep track of everyone. We will be back again next summer.

We love visiting and hanging out at Lost Island! I can soak in the sun while the kids have a blast all day long. Never a dull moment!

“Family fun for all ages all day long!”
Reviewed August 12, 2009

The park has many slides to keep the very daring child busy and even the not so daring mom! There are family slides with rafts that up to 4 people can go on. There is even a racing slide that keeps track of your time...my husband was able to act like a kid again! The park and restrooms are kept very clean. You can choose to eat at one of their restaurants, which can be a bit expensive or you can pack a cooler and take a break to eat out at your car. This saves money and allows everyone to regroup. We stay from open to close!
