I went here last year, what a fun place it is. Every slide apart from one tube slide are very thrilling and fun for everyonene. The wave pool is amazing and glad this place has one since its not very common to find wave pools at water parks. The splash pad is also very fun . Though being busy on a weekend, the lines weren't too bad

🏆 Family Action Verdict

Best for families with kids roughly 4 and up — the splash pad handles the youngest visitors as older kids and teens take on the slides and wave pool. The wave pool alone is a draw that sets Rolling Hills apart from comparable regional parks. Go on weekdays to avoid peak crowds and find seating more easily.

ℹ️ What to Know Before You Go

💡Weekday visits are significantly less crowded than weekends — seating is easier to find and wait times on slides are shorter.
Check Washtenaw County's official website for seasonal opening dates, session times, and any weather-related closures.
🎟️Bring your own chairs or a blanket — seating inside the park is sparse relative to crowd size on busy days.
🚗Arrive before opening on hot summer days; the park fills quickly and parking can become constrained.
