“The Waterpark Capital of the World!®” does it again! Mt. Olympus Water & Theme Park has officially announced it is building the largest outdoor pool in Wisconsin Dells. The Great Pool of Delphi, set to open mid-June, measures in at a whopping 27,000 square feet and includes four islands, a 100-foot geyser, children’s splash pad, 50-foot waterfall, and two zero-depth beach-style entrances. According to the owners, it will take more than a half-million gallons of water to fill it. While work continues on this newest water attraction, the other outdoor waterparks in the area are also gearing up for high season. Overnight guests of Wilderness Resort and Great Wolf Lodge will have the run of the place. Day passes are available at Chula Vista Resort, Kalahari Resorts & Conventions and Mt. Olympus Water & Theme Park. And of course there’s the outdoor waterpark that’s on every waterpark fan’s must-do list – Noah’s Ark Waterpark, the largest outdoor waterpark in the country. Makes you feel like Memorial Day weekend can’t get here fast enough, are we right?!
