Grizzly Jacks Grand Bear Resort sits about an hour west of Chicago in Starved Rock Country, and it's one of those combination destinations that actually pulls off both the water park and amusement park experience well. The indoor water park is the real star here, especially if you're visiting during Illinois' unpredictable weather months. The space feels surprisingly spacious for an indoor facility, with a decent-sized wave pool that generates some solid waves for body surfing and a lazy river that winds around a good portion of the park. The multi-level play structure in the kids' area keeps younger visitors busy for hours with its tipping buckets, smaller slides, and interactive water features. For older kids and adults, the tube slides provide the thrills, with a couple of racing slides that get competitive families going. What sets Grizzly Jacks apart is the combination ticket that gets you into both the water park and the adjacent amusement park. The outdoor rides include a decent wooden coaster and classic carnival rides that work well for families. The resort aspect means you can easily make this a weekend trip, though day visitors are welcome. The facility tends to get crowded on weekends, so arriving right when they open gives you the best shot at shorter lines. The cabanas book up fast during peak times, so reserve ahead if you want that extra space and shade. Food options are typical water park fare but reasonably priced compared to some resort destinations. The changing facilities are clean and well-maintained, which isn't always a given at combination parks. This place works best for families with kids ranging from toddlers to teenagers, since both parks offer age-appropriate attractions. The indoor setting makes it a solid choice for spring and fall visits when outdoor parks aren't quite comfortable yet.

Best time to go
Resort water parks are quietest mid-week and during the second half of any school break. Many resorts open the water park to overnight guests an hour before day-pass holders, so a one-night stay is often worth the math vs. two day passes.
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. Indoor and resort parks routinely run weekday flash sales, military and first-responder discounts, and second-day passes — check the deals page before booking.
Getting there
Grizzly Jacks sits in Utica, Illinois. Resort parking is usually free for overnight guests and ranges from $10–25 for day visitors. If you're a day visitor, ask the front desk about validating parking at the spa or restaurant — sometimes that's faster than the standard exit.
Who it's best for
