From the reviews

Awesome Park, had plenty to do and the Staff were amazing and personable. Only reason I did not give 5 stars is because after flipping over on one of the rides and my glasses flew off, the response I got was we will get them to you later in the day???

★★★★☆ — Aaron, Jul 2020

Awesome place for all ages! You can be 21+ and spend your day lounging with a drink in your hand, or you can be 3 years old running around in your life vest in the kids' pool. The food is great and not outrageously priced. Drinks are cold. Treats are delicious! Good value Waterpark. Glad it is so close to home!

★★★★★ — Nicole, Jul 2021

FUN place for all ages! Courteous staff! Parking & tubes are free. Water slides were FUN but elbows got banged up at the start of the slides. Lazy river & Wave pool were also very nice but breaks for waves to start were long. Food was good and not crazy expensive. Good value Waterpark!

★★★★☆ — Aide, Jun 2022

Great water park. I rented a cabana and it was totally worth it. With the cabana you can order food and the staff assigned to your cabana will get it and drinks for you so no lines. We had kids 8year to 13years with us, they kept busy the entire time.
