Ashley SparksThere'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.

Crystal HermosilloThis 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.

Chastity WilliamsonThe 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.

Jennifer PGreat water park for all ages! Plenty of lifeguards, big slides, small slides, big lazy river, and a little kid splash area!! Lots of chairs, but if you want a cabana, buy early in advance (they go quickly!) I heard the burger was dry, but the chicken tenders were good! You can save money if you bring your lunch and go out the park to eat! I've been a few times now with family and friends and will definitely be back!
