Island Waterpark

Though guests to Island Waterpark might meet humans on their way to the water, they might also encounter Pelican Pete—a giant blue pelican in a floral-print shirt and bermuda shorts. He and an athletic lifeguard staff oversee guests as they wander among fountains and roaring water in attractions designed for everyone from toddlers to adults. Bright-blue tube slides spiral down into splash pools, a giant bucket tips gallons of water onto passersby, and a three-story open slide sends riders on a straight shot into a landing zone that pads their descent with a foot of water and a coral reef packaged in bubble wrap. Aquatic revelers can also float down a 500-foot lazy river and children can frolic under arching fountains and waterfalls in a designated play area.
