New owners plan expansion for Raging Rivers Waterpark

An investment group has purchased Raging Rivers WaterPark and plans an expansion and upgrade for the 2021 season.

The 4-acre Grafton waterpark is adding cabanas and water slides, upgrading the kiddie pool and updating menus. The changes are planned for the opening of the 2021 season, May 22, 2021.

“2021 will be a year unlike any other at Raging Rivers Waterpark,” said Corporate Director of Operations Ken Handler. “We are adding more twists and turns, splashes, treats and places to kick back and relax for our guests and we couldn’t be more excited.”

The waterpark was purchased in October 2020 from Adams Development by an investment group, Raging Rivers LLC, led by Brian Buckwalter, Jim Mayoros and Handler. The investment group is focused on transforming Raging Rivers Waterpark into a regional resort with a dramatic new look and a new, major attraction for the upcoming season.

“This exciting new attraction will make a big splash and is the next step in delivering a world-class waterpark for our guests,” said Mayoros.

The purchase price was not disclosed but a release described the plans as a multi-million-dollar purchase and expansion.

The expansion will include more than 30 cabanas, three water slides, new additions to the kid’s aqua play area, and updated menus in the park’s concessions. The featured addition to the waterpark will be the water slide with three hidden chambers to speed down, splashing and spraying through the enclosed tubes before the final splash. Guests will be able to see this giant main attraction at the top of a hill as they enter the park, making a big, new statement.

Raging Rivers Waterpark provides unlimited splashes for families all season long for one low price, the lowest in the past 10 years. Right now, guests can purchase their 2021 season pass starting at just $54.99 plus tax per person for unlimited visits all season, in-park discounts and

other perks, like Bring A Friend tickets. Season Passes can be purchased online at this price through December 31, 2020 at

    From my wife about Raging Rivers in Grafton, IL
    I posted on my FB. 😡Now Raging Rivers will not allow any personal flotation devices! They would not let us bring our foam noodles in yesterday. We use them to swim in the Wave pool. If I don’t use one, my lower back feels like it’s breaking and my right knee replacement still hurts, so I can’t kick hard. The manager apologized. She said their new liability insurance will not allow personal floats. She gave us free tubes, but they are too big & impossible to swim with. We used the free life jackets, but they are too bulky and very hard to swim. 😥
    They also don’t allow tubes down the main 2 waterslides!
    “NO SHADE. NO FLOATIES. NO FUN!” Guess, we will not get Season Passes next year! I’ve had one every year since 1990. Very disappointed. This is Sam’s first summer ” Retired.” We were looking forward to having fun. Ugh…. 😡😖

    PS: I do not see any difference between our foam noodles vs the lifeguard red noodles. It is the same thing. The only thing I see is you guys picked the wrong insurance.
