There's a triple race slide and a straight down slide for 48" and up and 2 slides for 42" and up. Also the little 42" and under have a specific place to play with a couple slide as well which is great. It's worth the price. Pizza is $20 per medium pizza. If you leave ask for a stamp so you can come back in if it's same day. They have a wave pool that mimics the beach waves, kids 17 and under love it we brought 10 kids from ages 1 to 17 and they had a blast. Get a life vest if you need one right away as they run out quickly, and arrive at opening to get the most bang for your buck! We stayed from 10am to 3 because it started to storm. Also they only allow 2 bottled waters in per person but keeping a stocked cooler in your car is recommended. They offer beer and wine as well a margarita type drink but you must have id and sit at the bar to drink it.
Jun 28, 2026 · Google ReviewThe staff at the tables didnt care to check our bags like the website stated they would so I asked and she legit shrugged her shoulders and took my bag and half looked in it. 🤷♀️ There were a lot of liners in the lazy river coming up and it was dirty, In every crevice in the lazy river liner was dirt but you could smell the chlorine. I lost my glasses coming off the slide and asked 5 different staff members who should I ask to see if they're in the lost and found and they didnt know or if they even had a lost or found. Too many youngins working there that's there for a paycheck. But my kids had fun and that's what was important. Hornets were really bad at Kona ice truck by the flavored syrup and when I said something about it he said I know. I lot of kids under 48" were aloud on the big slides but my oldest is 51" and these kids were a good 6" shorter than her. Someone got hurt on one of the slides and it closed down for about 15-30mins we went August 2nd 2026. Needs to be cleaned better. Can't have expectations for some and not others and that's how it was. I didn't enjoy seeing womens nipples that my 8 yr old daughter pointed out at the wave pool and when they were going down the slides. I was in a 2 piece but an appropriate one that wasn't exposing everything for a family friendly environment.
Aug 4, 2026 · Google ReviewKona. ice quit serving smoothies because line too long? Finally went back when no line and said im only accepting cash now, what, guess we're not getting cool drinks on that side. Walked to other side waited maybe 20 minutes and said screw it. Had maybe 10 people in front of me and 6 behind me, way too long of wait. Did get in lazy river and like other reviews dead bugs through out. Not enough seating shared a picnic table with random nice couple, luckily. No were to sit at all besides that. Gave 3 stars because our 9 year olds had fun. Everything else 0 stars. Went out to my car and got stamped and told cannot come back in until pools reopened from thunder, which was fine until they let others in that were having a bday party? None of us were allowed in pool until time limit, so why im waiting to get back in and others can was stupid. Maybe train teach the kids checking to treat all the same. We are all paying customers.
Jun 28, 2026 · Google ReviewThe staff was very friendly, you're not allowed to bring goggles in for your children because it's a safety hazard? We didn't get there until 1:45 it stays open until 7:00 p.m. I only saw the bathrooms clean once they were horrid! You cannot bring in any outside food however it states that you can eat outside at its picnic area? They only had one picnic table??? For a place that flies and they had quite a bit of consumers. The reason I gave it three stars is everyone did have a great time. They have the lazy river, and four different water slides( children and young adults it was a water park and does it take much to please them). The cost is $24.99, if you're 48 inches $21.99 and seniors which I thought should be a little less than the rest but it was also $21.99.... I am enclosing pictures of the cost of food , I did forget to take pictures of the cost of the ice cones the small was $5 the medium was $6 the large was $7 and I believe you can continue to get refills for the large one up to four times. They did have four types of smoothies for $8.. hot dogs for $5.99 hamburgers for $8 pizzas were 1899 but they were delicious. I forgot to mention it did have a lot of lifeguards which I really liked. It also served some type of alcohol I believe beer I didn't even go to look. I would have given it more stars it goes bathrooms were filthy!!!!!!
Aug 25, 2026 · Google ReviewThis was our second time at this water park and it was just as fun as the first time! The kids had a good time, there was plenty of seats available all around the park, the food was good, and it's affordable for a family of 5.
