Raging Waves Water Park Voucher (Chicago)

USA Today named Raging Waves Waterpark in west suburban Yorkville a Top Illinois Summer Attraction, and Midwest Living Magazine placed the park on its "Best of the Midwest" list in both 2010 and 2011. Adults and kids can beat the midsummer heat with entry to the largest water park in the state -- admission with this offer is $15, regularly $29.

Park patrons can spend the day riding the 17 waterslides and splash in the wave pool, relaxing on the lazy river or watching the kids play in the Kangaroo Falls water playground. Included with admission is the new Sea Lion Splash, a thrice-daily show featuring Stella, Rose and Hansi, Raging Waves' team of acrobatic sea lions who dance and perform tricks in conjunction with their professional trainers.
