One of the best water parks I have ever been to. We drove 2 hours to come here and were super impressed! We visited on a Thursday and came from open to close and it wasn’t very busy. No more than a 5 minute wait for slides. #1 lazy river I’ve ever swam in. Food prices were super cheap compared to water parks in Omaha. $2.50 hot dogs, $3 walking tacos. $15 t-shirts! They have the coolest kiddie slide ever it’s like a slip and slide and super cushiony at the bottom which is a big deal to me. I can’t stand coming down a slide or my kids going down a slide and then scraping feet. The life guard at the slide was friendly and would give kids a boost which I thought was nice. All the staff were actually really helpful and friendly. They seemed to actually enjoy their jobs. The park has 2 giant slides, 4 big slides, a wave pool, an obstacle course, lazy river, water basket ball hoops, splash park type area, kiddie slide, sand play area and concessions. $30 for my family of 5 to get in. Very nicely up kept. We will be back and bringing friends! Oh and the decor really gave it a tropical feel. I loved all the pretty flowers and the fake palm trees. 10/10

Wow!! Island Oasis is clean. Lifeguards are alert and friendly. I can't rave enough about the prices! Even the concession were affordable! For 1 adult and 3 kids the admission was 33.00. For all of us to eat it came up to 17.00! We spent from 1pm-7pm here and my kids had a blast the whole time. There are 6 slides, however the 2 really big ones were closed. But that didn't spoil our fun. If your looking to get away from Omaha..or just passing thru grand island, this is the place to go!

Fun, clean, affordable water park for the family. With plenty of concessions.

Love it here, not super huge but a nice little place to go and have a nice day out with the kiddos. The pricing is very affordable. Food and drink available. Locker and tube rentals are reasonable as well. We will be here all summer!

While visiting family in the area I came across little gem. One of the best small town watermarks I've been to. There are more than enough chairs and sitting areas to for your family or party, the food and ice cream is delicious and it has a little bit of everything you'd find at a bigger waterpark!

Absolute hidden gem. Don't miss this if you're driving by on the 80. $26 total for two adults and two children (under 5 was free). The lifeguards were very accommodating to our child who is an amputee. Even at peak hours (Saturday afternoon), it wasn't overly busy and the lifeguards were very aware of everyone. The water slides were awesome! There's a nice progression for those unfamiliar with water slides - two open topped slides that are slow, two enclosed tube slides that are faster, and then the two high slides. I tried them all - very fun! The lazy river was warm and they always had ample tubes. No hidden tube fees or anything. Just cost of entry and concessions, which I felt were also very reasonably priced.

Loved the lazy river. We went on a cooler cloudy day so it wasn't very busy. 7/11/2021 The steps up to the slides need serious maintenance though since a couple spots had boards that my nephew almost fell through.

Happened to be passing through the area, and found this gem along the way. Affordably priced, well staffed, and GREAT fun for my kids (ages 9, 8, 5, 3). Stayed the whole afternoon, and the kids never got bored. Smaller than some water parks, but plenty to do.

The slides were down when we visited which one of my daughters was bummed about. But fun none the less, they have a Lilly pad and branch obstacle course, wave pool and lazy river that my kids enjoyed.

The staff must have still been tired from the previous night, there was no pizza. Out of the 3 different styles of tornadoes they only had one. The lazy river is nice , it's sperate from the main pool, so that kinda sucks as when floating there is nothing to see. Other then that the water park was fun, the slides were a blast, a walk to the top but worth it. Would be a full rating if the full staff was more friendly.

This is a fun place. Sometimes that's all that really needs to be said. I highly recommend this place, bring sunscreen. There is a lazy river, four small twisty slides, wave pool, a toddler/small child area and two large slides. I'm a big fan of the 4 twisty slides. There is also tube rental and small snack bar/restaurant (with only slightly higher then normal prices). There is a sand area and some shade. ***NOTE*** The lazy river provides it's own tubes, don't rent one for it. What it's missing is a diving area, the deepest this place gets is 5 feet.

We had a great time at this water park! Kids ranging from 5-15 all enjoyed themselves. Great sight lines for keeping an eye on the younger ones and plenty to do. Wave pool was kinda weak, but that was the only complaint. Highly recommend!

I hadn't been to Island Oasis in probably 15 years and had been worried about it being over crowded and trying to keep track of kids. Not sure if it was early in the season (2nd day open and right at noon), but it wasn't overly crowded. Something to do for every age. Only downside is price but they have a lot of life guards on duty keeping people safe.

Seems like new tubes in the lazy river this year. The snack bar is pretty good. Speed slides ridges will murder your back. The others are ok. Wave pool seemed like it was broken last time we were there and barely makes waves. Still ok place to visit.

Overall this Water Park is awesome. Lots of variety. Go mid-week when there's less people. Kids need to be good swimmers to go down the medium/large slides. Toddler slide has lots of cushion. Obstacle course was fun. Sand from the beachy area gets in the pool, wish there was showers to rinse off by the sand area. There were 2 main Negatives for us: 1. Lifeguards are ALL teenagers, so politeness/helpfulness varies. They need more training on communication and taking initiative to offer help. One of the lifeguards was PRETTY rude. 2. The lazy river did NOT have clear guidelines for toddlers in lifejackets, which caused quite a bit of stress for us. Don't put toddler in their own float... mine slid down into it too much, kept getting jammed inside with her lifejacket twisting her arms up and she couldn't hold on. It actually pushed her down into the water more. So we went up to a lifeguard and she agreed it was DANGEROUS and took the float for us, and she said my toddler would be fine if I held onto her. So I just held her hands and went on. This was mostly fine, but there were a couple of places that the current was stronger or I had to block other people from running into her etc. Made us both nervous so we were just going to get out after that lap. Near the end, another lifeguard whistled and told us she needed a float. He was next to a big fountain that was very loud so communication was limited. As I slowed to stop, I told him the other lifeguard told us to do this and reason. Then he said to put her in my float, kind of rudely. I didn't think of this as I'm pretty pregnant and there's not much room. So I got stopped and thought about how to get her into my float and make her fit, and the lifeguard just kept whistling and yelling at me EVERY 3-5 seconds.The 6th time he sounded angry, and I was worried I was going to get kicked out, or sound mouthy if I yelled back a confirmation over the sound of the fountain. I was struggling to get her up into my float and really JUST NEEDED HELP. It was SO frustrating and embarrassing. I eventually figured out a way to get her up into my float, and it was tight but worked better than I thought it would. He should have come down and politely collaborated with me and offered to help. And we really should have been instructed to do that from the very beginning. But aside from the lazy river drama, we had a great time.

Do not do swim lessons at Island Oasis. If the time you signed up for, doesn't have enough kids, determined by the life guards not based on standard policy, then they will make you move to another time or tell you "sorry if it's not going to work out. We can give you a refund". I don't want a refund. I want my kids to learn to swim at the time I signed up for back in April.

I brought my daughter here for the first time. They wouldn't allow her to use her floating device she is comfortable with. I was understanding as they have rules and that's fine. But the "tube" they gave my daughter was huge. She's 5 and basically had a terrible time because she was constantly slipping off the giant tube. Also took the lazy river and I think it's gotten a little lazier. Used to move a little quicker. Or at least that's how we feel.

Our experience was great. We had a large group of people for an event. And Brady the manager made it really easy to set up. And the kids and everyone had a lot of fun. We are not from the area. We loved it. My most favorite was the lazy river.

It is actually a great little water park. Very kids friendly. We all had a blast. I definitely will be bringing my family back.

More speakers needed for music. Also, a full size official swimming pool with dive boards. How about add a kid's dump bucket. And, stay open for the State Fair, even if just for the weekends. High school lifeguards should still be available.

One of the best water parks in the state. It's cheap and lots of fun on a hot day. Highly recommend.

Fantastic place to bring the kids, do some swimming, get a tan, etc. The concessions are wonderful, although the walking tacos could use more meat. Slides are a lot of fun! I will definitely go back! P.S. The entry fee is very reasonable, and you have an option to purchase a season pass (and save $$$).

Kids had a blast. Concessions were fairly priced, for $3 you can get a combo meal. Lifeguards and other staff were attentive as well as friendly. Admission was decent in price, locker area and bathrooms were fairly clean and lots of activities to do for kids to stay busy.

Great place for family and the kids and the concession is very affordable! Wave pool, lazy river and 6 slides as well as a slide for the little ones and a big area dedicated to the little ones!
