It is loud. If you walk into the lobby during a peak Saturday in July, the first thing you notice isn't the rustic wood beams or the massive fireplace—it's the sound of a hundred kids who just realized they’re five minutes away from a water slide. For years, people knew this place as Grizzly Jack’s Grand Bear Resort Utica, and while the "Grizzly Jack" branding has largely faded into the background after ownership changes and a pivot toward the "Grand Bear Resort at Starved Rock" identity, the DNA of the place remains the same. It’s a chaotic, chlorine-scented, wood-shingled slice of Illinois vacation history.
Located literally a stone's throw from the entrance of Starved Rock State Park, the resort serves a very specific purpose. It’s the bridge between "I want to hike through canyons" and "I want my kids to be exhausted enough to sleep through the night." Honestly, it’s a weird mix. You have one of the most beautiful natural landscapes in the Midwest right outside the door, and inside, there’s a massive indoor waterpark with a wave pool.
What Actually Happened to the Grizzly Jack’s Name?
Business transitions are usually boring, but for locals and long-time fans, the shift from Grizzly Jack’s to the current branding felt like the end of an era. The resort opened in the early 2000s with a massive vision: a Northwoods-themed destination that could rival the Wisconsin Dells without the three-hour drive from Chicago. Over time, ownership shifted. When you look at the records for the property in LaSalle County, you see the evolution of a resort trying to find its footing in a competitive market.
The name "Grizzly Jack" was a mascot-driven brand. Today, you’ll see it mostly referred to as Grand Bear Resort at Starved Rock. Why? Because Starved Rock is the magnet. The park pulls in over two million visitors a year. By tethering the resort name more closely to the state park, the marketing became a lot more effective. It wasn't just a standalone waterpark anymore; it became the "place to stay at Starved Rock."
If you're looking for luxury, you're in the wrong place. This isn't the Ritz. It's a high-volume family resort. The carpets have seen some things. The elevators are sometimes slow. But for a family coming from Aurora or Joliet, it's the gold standard for a weekend getaway that doesn't involve a flight.
The Waterpark Reality Check
The centerpiece is Grand Bear Falls. It's a 24,000-square-foot indoor waterpark. Now, compared to the mega-resorts in the Dells like Kalahari or Wilderness, 24,000 square feet is actually somewhat modest. But size isn't everything when you're chasing a toddler.
The park features:

- A lazy river that is actually quite relaxing if you get there before the noon rush.
- Two large slide towers.
- A wave pool that triggers every ten minutes or so.
- A massive play structure with a tipping bucket.
The water temperature is usually kept around 84 degrees. It feels humid. Like, tropical-rainforest-in-a-basement humid.
One thing people often miss is the outdoor area. In the summer, there’s a splash pad outside that helps thin out the crowds inside. If you’re planning a trip, the biggest piece of advice I can give you is to check the waterpark hours before you book. They fluctuate. Sometimes they aren't open on Tuesdays and Wednesdays during the off-season, which has led to many a frustrated parent in the lobby. Always call. Don't just trust the website's booking engine.
More Than Just Toes in the Water
While the waterpark gets the headlines, the resort is a massive complex of villas and cabins. This is where the Grizzly Jack’s Grand Bear Resort Utica legacy really shines. The accommodations are huge.
You have the standard lodge rooms, sure. They’re fine. Two queens, a TV, maybe a view of the parking lot. But the villas? Those are the game changers. We’re talking about multi-bedroom units with full kitchens and whirlpool tubs. If you're doing a family reunion, this is the move. You can cook your own pasta, avoid the resort food prices for one night, and actually have a door between you and the kids when they’re watching cartoons at 6:00 AM.
The Northwoods theme is heavy here. Lots of pine furniture. Lots of bear-themed art. It’s "cabin chic" but on a commercial scale.
The Enchanted Forest and Arcade
The "Enchanted Forest" is their indoor amusement park. It has a canyon-themed mini-golf course and a few rides like a small drop tower. It’s great for when the kids are pruned from the waterpark but still have energy to burn. The arcade uses a card system, which is convenient but also a very easy way to lose $40 in twenty minutes if you aren't watching the "play" vs. "bonus" credits closely.

Eating at the Resort (and Nearby)
Dining at Grand Bear is... functional.
Jack’s Place serves your standard American fare. Burgers, wings, pizza. It’s what you expect. It’s fine. But here’s the thing: you are in Utica. You are five minutes away from some of the best small-town eats in Northern Illinois.
If you want a real meal, leave the property.
- Lodi Tap House: Go here for the burgers. They focus on Illinois-sourced ingredients and have a massive craft beer list.
- The August Hill Winery Tasting Room: This is for the adults. It’s right in downtown Utica. Grab a flight of locally made wine and breathe in the silence for a minute.
- Cajun Connection: It’s an Illinois legend. Ron Williams, the owner, brings authentic Louisiana flavor to the cornfields. Get the gumbo. Seriously.
Staying at the resort but eating in town is the pro move. It supports the local economy and generally tastes better than high-volume resort food.
The Starved Rock Connection
You cannot talk about this resort without talking about the canyons. Starved Rock State Park and its neighbor, Matthiessen State Park, are the reasons this resort exists.
Most people flock to Starved Rock, which is beautiful but can get incredibly crowded. If the parking lot at Starved Rock is full (which happens by 10:00 AM on many weekends), head to Matthiessen. It’s just as beautiful, the rock formations are arguably cooler, and it's usually a bit less congested.

The hiking here is legit. You’ll find St. Louis Canyon, French Canyon, and Wildcat Canyon. After a morning of hiking three or four miles through sandstone bluffs, coming back to the resort for a soak in the hot tub feels like a literal godsend.
Practical Insights for Your Trip
Don't be the person who shows up without a plan.
- Check-in vs. Waterpark Access: You can usually get your waterpark passes before your room is actually ready. Pack a separate small bag with your swimsuits and towels. Check in, get your wristbands, and hit the slides while the cleaning crew finishes your room.
- The Towel Situation: They provide towels in the waterpark, but they are small. Like, "barely covers a toddler" small. Bring your own beach towels from home.
- The "Quiet" Times: If you want to avoid the madness, Sunday night through Thursday night is the sweet spot. The prices drop significantly, and you won't be fighting for a plastic chair by the wave pool.
- Safety First: The lifeguards at Grand Bear are generally very attentive, but the wave pool can be surprisingly strong for small kids. Keep the life jackets on them—they are available for free in the park.
Grand Bear Resort has survived floods, economic shifts, and a major rebranding. It remains a staple of Illinois tourism because it provides a predictable, fun, and relatively affordable escape. It’s not a five-star spa retreat; it’s a place where kids can be loud, parents can relax a little, and everyone leaves with a bit of sand (or chlorine) in their hair.
Your Next Steps for a Utica Getaway
If you're ready to pull the trigger on a trip, start by looking at the resort's mid-week "stay and play" packages. They often bundle the room and waterpark passes at a much lower rate than if you book a Friday-Saturday block.
Before you leave, download the AllTrails app and look up the "Starved Rock and Matthiessen Area." Map out your hikes ahead of time. Start your hike at 8:00 AM, finish by 11:00 AM, and spend the heat of the afternoon in the waterpark. This schedule lets you beat the park crowds and maximize your resort fees. Finally, make a reservation at a local Utica restaurant for Saturday night at least a week in advance; the town is small and fills up fast when the resort is at capacity.
