Important information regarding Holly Recreation Area Parking & Occupancy

A Michigan Recreation Passport is required to enter Holly Recreation Area by car. Prices and more information can be found at . In person purchases with the DNR at Holly Rec are cash only, please bring cash if you plan to purchase the day of your visit. (Credit cards are accepted at the campground across the street.)

To ensure visitor safety, there are times when Heron Beach and/or Holly Rec Area may reach capacity (especially on holidays, holiday weekends and special events). If this happens, your WhoaZone ticket does not guarantee you admission into the outlying park, only into the WhoaZone facility. During busy times we strongly urge you to arrive early in the day, regardless of your scheduled splash session time. Missed sessions due to city or state park capacity will be handled on a case-by-case basis, however, WhoaZone is not responsible for closure due to local city, county, or state regulations.
