Raging Rivers sits right along the Mississippi River bluffs in Grafton, giving you actual scenery while you're getting soaked. The massive wave pool is definitely the main event here, and it gets pretty intense when they crank up the waves every 15 minutes. You'll see kids getting tossed around while parents try to keep their footing closer to shore. The body slides are solid tube rides that give you a good rush without being too extreme. They've got a decent kids area with smaller slides and fountains that keeps the little ones busy while older siblings hit the bigger attractions. The lazy river winds around a good chunk of the park and actually stays relaxing since it's long enough that you're not constantly bumping into other tubes. What really sets this place apart is the riverside location. You can actually see the Mississippi from parts of the park, which beats staring at parking lots like most water parks. The facility feels more like a regional destination than just another suburban splash zone. Get there early on summer weekends because parking fills up fast and the wave pool gets crowded by noon. The concrete gets scorching hot by midday, so water shoes are pretty much mandatory. Food prices are typical water park expensive, but the portions are decent. Rent a tube for the lazy river right when you arrive since they run out on busy days. This park works great for families with mixed ages since there's enough variety without being overwhelming. Teens will have fun but might get bored faster than at bigger parks with more extreme slides. The charm here is the laid-back Mississippi River vibe rather than non-stop adrenaline.

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 Grafton, Illinois. 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.
