Six Flags has acquired its 20th property, entering an agreement with Waterworld California owner EPR properties to operate the attraction in Concord.

The largest waterpark in California is 30-acres and opened in 1995 under the Six Flags banner, operating as such until 2006 when it was acquired by Premier Parks.

“This is an exciting new venture and a great opportunity to provide families with more entertainment options in this important market,” said Six Flags CEO, John Duffey. “Guests in Northern California will now have the opportunity to enjoy two beautiful Six Flags parks. This is truly a win-win, as we welcome our 20th property – Waterworld California – back into our family of parks.”

Waterworld California has more than 35 attractions, including the region’s largest wave pool, an interactive children’s play area and its newest offering in Break Point Plunge – ProSlide’s 270ft (82m) SuperLoop with Skybox Technology.

The park reopens for the 2017 season on 13 May. The agreement is subject to approval by the City of Concord.
