We had never been to Adventure Island before. It was a nice waterpark with many attractions and slides for everyone to do. Parking cost $12. The park opens at 9:00 and I would recommend getting there early if at all possible. We were able to try out many of the slides before it got too crowded. By 11 o'clock, the park was definitely filled. There were a lot of summer camps going on there as well. I would also recommend to find a nice shady place to put your things. You are allowed to bring in a small personal cooler with drinks and food. A lot of families were having picnics and lunch there. My family and I left at 2:00 because things were just getting too crowded. All in all, I am glad we had the chance to visit. It was a good day to cool off from the summer heat!
