Walking through the gates at Lost Island will make you feel like you just stepped off a plane in some far away destination. We offer a wide range of attractions for all thrill levels. Enjoy the Wailua Kupua - one of the first hydromagnetic watercoasters in the country! Splash around in Tsunami Bay, race your friends down Ta'Katipo, lounge in a deluxe cabana, or float around the Kailahi River. With over 14 different rides available, it won't take long for you to get lost.

Bought the two day ticket and it was worth it! Had an excellent time, lots of fun! I would recommend some improvement in the bathroom area, there's only one mirror and it needs more area to accommodate personal items while changing clothes. But we had a great time! Prices are super reasonable and staff is very friendly! Would recommend this... More

The lazy river was nice and refreshing, however could use some more shade. The wave pool was dangerous! There were so many people in there. I got kicked more than once and my entire side was bruised because of it. The need to limit how many people are in each attraction for safety reasons. On the plus side, there are... More

Great water park! Plenty of attractions for the little ones and the teens. Busy as it was hot today! Take a picnic for lunch!

I wish it wasn't super busy every time we go. It makes it hard to enjoy yourself when you are constantly having to watch out for yourself or be trampled. The red slide left marks on my older daughters back. There's much more things to do for the older kids. The decorations give it a nice tropical feel. My favorite... More

Took the family for 18 holes of miniature golf. Haven't played in a long time. It was a decent price and we had fun. No electronics involved. They can't wait to go back again.

This is an awesome water park. Has over a dozen large water slides as well as a wade pool and lazy river. Definitely worth coming to for a day. There is even two mini golf courses and a zip line on the grounds as well (have to pay separately for them)

Our family of 6 reserved one of the deluxe cabanas. Worth the cash. Water in the fridge and a locker with key. Comfy furniture and a good view of the park. We were able to spot our kids and relax at the same time. We got a $4 off per person coupon because we are staying at the KOA across... More

We really love attending this water park. There is a very long lazy river to see all the attractions. In fact, I once lost sight of my 8 year old who was with a few friends. We rode the lazy river to find her, and it worked. You may want to wear water shoes, the steps can get really hot... More

I have been going to Lost Island since they opened 16 years ago. Through the years I have given many waterparks a try, but Lost Island is the best! Give it a try you won't be disappointed!!!
