The Gerald E. Eddy Discovery Center is the visitor center for Waterloo Recreation Area, at 17030 Bush Road in Chelsea. It makes a relaxed family day trip: an exhibit hall on Michigan’s geology and habitats, live local animals, a short film, and easy trails that start at the door. From The Oaks Campground in Munith it’s about 18 miles, or about 35 minutes by car, which makes it an easy morning out before an afternoon back at the beach.
Our team hears about it from guests all the time. When we asked staff where Oaks campers go most once they leave the gate, Waterloo and the Eddy Discovery Center were at the top of the list.
What is the Gerald E. Eddy Discovery Center?
It’s the Michigan DNR’s interpretive center for Waterloo, the largest state park in the Lower Peninsula at more than 20,000 acres. The center explains how the glaciers shaped this part of Michigan and what lives in the habitats they left behind: beech-maple forest, hardwood swamp, bog, oak barrens and prairie fen.
The building reopened in April 2026 after a yearlong renovation that added a new roof, a modernized atrium, new heating and cooling, and new exhibits. If you visited years ago, it’s worth another look.
How far is the Eddy Discovery Center from The Oaks?
About 18 miles and about 35 minutes by car. You’ll drive east through the recreation area toward Chelsea. Golf carts stay at the campground, so take the family car. Because Waterloo is a state park, a Michigan Recreation Passport is required for vehicle entry; Michigan residents usually add it when they renew their plates.
Gerald E. Eddy Discovery Center hours during camping season
The center keeps a seasonal schedule, so the day of the week matters. Here is how the DNR’s posted hours line up with our May 1 to October 20 season:
| When you’re camping | Center open | Hours |
|---|---|---|
| May, before Memorial Day | Saturday and Sunday | 10 a.m. to 4 p.m. |
| Memorial Day to Labor Day | Daily | 10 a.m. to 5 p.m. |
| Labor Day to October 20 | Saturday and Sunday | 10 a.m. to 4 p.m. |
Hours can change for holidays and special events, so check the DNR’s Eddy Discovery Center page or call the center before you go.
What kids will like inside
- The critter room. Live, local animals, plus displays on how animals adapt to Michigan’s seasons.
- A giant map of Waterloo. An interactive map shows the habitats around the park. It helps kids picture where the deer, cranes and turtles they see at camp actually live.
- Ice Age to today. The exhibit hall walks through Michigan’s geology and habitats from the glaciers through European settlement. Look for the fluted spear points used by Paleo-Indian hunters and a dugout canoe.
- A working beehive. The atrium has an active honeybee colony behind glass and a touch-screen bird game.
- A 12-minute film. The auditorium shows a short introduction to Waterloo. It’s a good way to start the visit before younger kids get restless.
The center also runs public programs for all ages, such as archery and night hikes. Program dates change through the year, so look at the DNR schedule when you book your site.
Short trails at the Eddy Discovery Center
Several short loops start near the center, and they’re a good size for kids. Trail guides list these approximate lengths:
- Old Field, about 0.8 mile
- Spring Pond, about 1 mile
- Lowland, about 1.1 miles
- Oak Woods, about 1.3 miles, with views of Mill Lake
- Bog Trail, about 1.5 miles
- Lakeview, about 1.5 miles, from its own trailhead on McClure Road
The Waterloo-Pinckney Trail also passes the center.
A family day trip from The Oaks
Here’s how a lot of our families would plan it:
- Breakfast at the site, then leave camp around 9:30 so you arrive when the doors open at 10.
- The film and the exhibits first, while everyone is fresh. Budget about an hour.
- One short loop, such as Old Field or Spring Pond, before it gets hot.
- Lunch in Chelsea, about 10 minutes further east.
- Back to camp for the afternoon. The sand beach on our spring-fed swim lake, the Aquaglide floating water park and the free Kangaroo Jumper are all waiting, and you’re back in time for a food truck dinner on event weekends.
That rhythm is why we like this trip. As our team puts it, you can’t do everything at the campground and everything in the area in one weekend, so many families save the Discovery Center for a cooler or cloudier day.
Why camp at The Oaks for a Waterloo visit?
The Oaks is a nature-first campground on 155 acres, with about 120 acres of our own trails, right next to Waterloo and sharing a border with the Haehnle Bird Sanctuary. Sites are large, from about 35 by 65 feet up to 55 by 120, with 50-amp electric and water on short-term RV sites (30 amp on seasonal sites) and wooded tent sites. Quiet hours run 11 PM to 8 AM. Waterloo’s state campgrounds are a good choice too if you want to sleep inside the park.
Rates vary by date and site; see The Oaks rates page to book your site.
Questions
Is there a fee to visit the Eddy Discovery Center?
The DNR doesn’t list an admission fee on its center page, but a Michigan Recreation Passport is required for vehicles entering state parks. Call the center if you want to confirm before you go.
How long should we plan at the Eddy Discovery Center?
Most families need about an hour for the film and exhibits, plus 30 to 45 minutes for a short loop trail.
Is the Eddy Discovery Center open in October?
After Labor Day it’s open Saturdays and Sundays, 10 a.m. to 4 p.m., until mid-November. That covers October weekends during our season.
Can we drive our golf cart from The Oaks to the Discovery Center?
No. Golf carts stay inside the campground. The center is about a 35-minute drive.
Where can kids keep spotting wildlife back at The Oaks?
On the campground’s own trails. One loop heads toward the wetlands along Haehnle Sanctuary, where sandhill cranes are common, and the forest loops are full of deer, since there’s no hunting at the campground. Turkeys, eagles, hawks and herons are regular sightings too.
What’s a good way to finish a Discovery Center day?
Head back for the beach. From Thursday through Sunday in season (through Labor Day) the Aquaglide is open for ages 7 and up, and the Kangaroo Jumper by the store is free for campers any day.
