Raging Rivers in Mandan gives you that classic small-town water park experience without the massive crowds you'd find at the big destination parks. The slides here are the main draw - a handful of body slides and tube slides that pack more punch than you'd expect from a park this size. The twisting tube slide gets surprisingly fast toward the bottom, and the open body slides give you that stomach-drop feeling that bigger kids and adults love. The kiddie area sits in its own section with smaller slides, fountains, and shallow play features that keep the little ones busy for hours. Parents appreciate being able to see the entire area from the shade structures around the perimeter. What makes Raging Rivers work is its manageable size. You can walk from one end to the other in under two minutes, which means parents don't lose track of kids, and you're never far from the snack bar or restrooms. The park attracts mostly local families, so it has that community feel where kids make friends in line and parents chat while watching from the sidelines. Lines move quickly even on busy summer weekends. The park works best for families with kids between 5-15. Toddlers have plenty to do in the kiddie section, and older kids get enough thrills from the main slides without getting bored. Teenagers might want more variety, but they often enjoy the relaxed atmosphere and freedom to roam. Get there right when they open to claim a good spot for your chairs and coolers. The shade areas fill up fast on hot days. Bring your own snacks if you can - the concession prices are reasonable for a water park, but you'll save money packing lunch. Don't forget extra sunscreen; the North Dakota sun is stronger than you think, especially with all the water reflection. The grass areas around the park are perfect for setting up camp for the day.

Best time to go
Late June through mid-August. Weekday mornings are quietest. Skip the week of the 4th of July and the first week most schools let out.
Save money
Online tickets typically save you a few dollars over the gate price; even at lower-priced parks it adds up for a family. Outdoor parks usually drop ticket prices after 3pm or 4pm; if you're a half-day family that schedule alone can save 30%.
Getting there
Raging Rivers sits in Mandan, North Dakota. Arrive 15 minutes before opening. Lots fill fastest on Saturdays and the lots farthest from the gate fill last — useful if you don't mind the walk.
Who it's best for
Fits a wide range of ages. Worth a scouting lap when you arrive so each member of your group knows where their favorite area is before lines start to build.
