Colorado's largest water park has a major construction project planned this offseason. Water World said its Calypso Cove area will be retired after more than 40 years and rebuilt with new attractions. The Calypso Cove section of the park — home to Screamin’ Mimi, Tortuga Run, Pirates Plunge, and Wally World — will be closed beginning Monday, Aug. 25. "Calypso Cove will be retired and re-imagined to make way for an exciting new chapter at Water World," said a park statement. "These changes will bring fresh attractions and modern amenities that will better serve families, groups, and guests of all ages for years to come. We know how much Calypso Cove means to our community, and that saying goodbye is never easy." The last day to ride Screamin’ Mimi, Tortuga Run, Pirates Plunge, and Wally World will be Sunday, Aug. 24. Water World said a Calypso Cove farewell celebration will be held on Sunday, Aug. 24. The park said there will be free popsicles, mascots, swag and prize giveaways. Water World said it would share more details about its new attractions planned for the 2026 season later this fall. Water World opens Memorial Day weekend in 2026.
