Our take
4/5Rock'N River Water Park pairs a seasonal outdoor pool with birthday packages and reserved rental areas. The Splash package includes 16 guests, admission, ice cream, a drink, sunglasses, and two return passes for the birthday child. The Rock'N package includes eight guests and one return pass. Families can choose from water slides, swimming, and a lazy river during the operating season.
Package prices range from $200 to $350 depending on the option and day, with a separate rental-area fee and $30 for each added guest. Check the seasonal calendar and rental space cost before inviting a group; the total depends on both choices.
