If you’ve spent any time in Central Wisconsin, specifically around the Wausau area, someone has probably told you to just "go to Bluegill." They’re talking about Bluegill Bay County Park. It’s one of those places that feels like the community’s collective backyard. It isn't a massive, sprawling wilderness like a National Park, but it hits that sweet spot of accessibility and genuine "up north" vibes without requiring a three-hour drive into the sticks.
Located right on the western shore of Lake Wausau in the Town of Rib Mountain, this park covers about 68 acres. That’s big enough to get lost in a thought, but small enough that you won't actually get lost in the woods.
People come here for the water. Honestly, that’s the main draw. Lake Wausau is technically a reservoir on the Wisconsin River, and Bluegill Bay sits in a prime spot to access it. You've got boat launches, hiking trails, and those classic picnic shelters that smell faintly of charcoal and old wood. It’s a vibe.
What You’re Actually Getting at Bluegill Bay County Park
Let’s talk logistics because nothing ruins a Saturday like showing up to a park and realizing you can’t do what you planned. Bluegill Bay County Park is split into a few functional areas. There’s the "developed" part with the asphalt and the playground, and then there’s the more rugged, marshy section that birdwatchers go nuts for.
The boat launch is a heavy hitter here. It’s one of the most popular access points for Lake Wausau. If you’re pulling a Bass Tracker or a couple of kayaks, this is your home base. The water can get busy on holiday weekends—think Fourth of July chaos—but on a random Tuesday morning? It's glass.

You've also got two main shelter areas. These are the "North" and "South" shelters. They’re built with that heavy timber aesthetic that screams Wisconsin Department of Natural Resources (DNR) style, even though it’s a county-run joint. You can rent these out for graduation parties or family reunions where your Great Aunt Linda complains about the humidity. They have grills, electricity, and nearby pit toilets. Speaking of toilets, they are well-maintained for park standards, but they’re still park bathrooms. Manage your expectations.
The Hiking Trails and the "Hidden" Island
Most people stay near the parking lots. Don't be most people.
The trail system at Bluegill Bay County Park isn't going to challenge a seasoned mountaineer, but it’s interesting because it winds through diverse terrain. You’ve got lowland hardwood forests and then—suddenly—you’re in a marshy wetland.
There is a bridge. It crosses over to a small island. This is the spot.
Walking across that bridge feels like leaving the city behind. The noise from the nearby highway (I-39/US-51) fades out, replaced by the sound of red-winged blackbirds screaming at you for getting too close to their nests. It’s one of the best spots in Marathon County to see migratory birds. Seriously, if you have binoculars, bring them. You might see Ospreys, Bald Eagles, or even the occasional Great Blue Heron standing perfectly still in the shallows like a statue.
Fishing: Is it actually good?
Well, the park is named Bluegill Bay. So, yeah, there are bluegills.
But it’s not just panfish. Lake Wausau is known for:
- Walleye (especially near the river channels)
- Northern Pike (look for the weedy edges)
- Musky (they’re in there, but they’re jerks)
- Largemouth Bass
Fishing from the shore is okay, especially for kids. There are several spots along the bank where the brush has been cleared. However, if you really want the big ones, you need to get out on the water. The bay itself is relatively shallow, which means the water warms up faster in the spring. This makes it a prime spawning area. If you’re out there in late May, the shallows are buzzing with activity.
Winter is a Different Beast
Don’t think this is just a summer spot. When the temperature drops and the lake freezes over, Bluegill Bay County Park transforms into a hub for ice fishing.
You’ll see the "shanty towns" pop up. It’s a local tradition. Guys (and plenty of women) haul their heated huts out onto the ice, drill a few holes, and sit there for eight hours drinking coffee and waiting for a tip-up to flag. It’s quiet. The air is sharp. The light off the snow is blindingly bright.
Cross-country skiing and snowshoeing are also big here. The trails aren't always perfectly groomed like the ones at nearby Nine Mile Forest, but for a quick workout after work, they’re perfect. Just watch out for the wind coming off the lake; it’ll bite your face off if you aren’t layered up.
The Reality of the Environment
We have to be honest about the water. Lake Wausau is an impoundment. Because it’s part of a river system that has seen a lot of industrial use over the last century, there are consumption advisories for the fish.
The Wisconsin DNR puts these out every year. Usually, it’s a recommendation to limit how many meals of walleye or pike you eat per month due to mercury or PCBs. It’s not "don't touch the water" dangerous, but it is "read the sign before you fry it" serious. Most locals catch and release, or they’re very selective about what they keep.
Also, the weeds. By late August, the bay can get "soupy." It’s a shallow bay in a nutrient-rich lake. Milfoil and other aquatic plants can get thick. If you’re running a motor, you’ll be clearing your prop every ten minutes if you aren't careful. Kayakers usually don't mind, but it’s something to know before you launch a deep-V hull boat in late summer.
Why Rib Mountain Matters Nearby
You can’t talk about Bluegill without mentioning Rib Mountain State Park, which looms over the horizon. The two parks complement each other. Rib Mountain is all about the elevation, the views, and the quartzite rock. Bluegill Bay is about the water level, the silt, and the life at the edge of the river.
If you're visiting from out of town, do both. Hit Rib Mountain in the morning for the hike and the observation tower, then head down to Bluegill Bay for a sunset picnic. The view of the mountain from the park at sunset is actually one of the best photo ops in the county. The granite glows purple. It’s worth the bug bites.
Practical Advice for Your Visit
First, check the Marathon County Parks website if you’re planning a big event. You need permits for the big shelters, and they book up months in advance.
Second, bring bug spray. This isn't a suggestion. It’s a survival tip. The "Bay" part of the name implies standing or slow-moving water, which is essentially a five-star resort for mosquitoes. From June through August, they are relentless, especially in the wooded sections of the trails.
Third, if you’re launching a boat, get there early. The parking lot for trailers isn't infinite. On a sunny Saturday, it fills up by 10:00 AM. If you show up at noon, you’ll be circling the lot like a vulture.

Bluegill Bay County Park represents the best of Wisconsin’s "middle ground." It’s not a rugged wilderness, but it’s not a manicured city park either. It’s a place where you can smell the pine needles, hear the water lapping against the shore, and still be at a grocery store in five minutes if you forgot the mustard for your brats.
Actionable Steps for Your Trip
- Check the Weather: Wind speeds over 15 mph make Lake Wausau choppy and difficult for paddleboarding or canoeing.
- Download a Map: While the park is small, the trail loops in the marsh can be confusing if you aren't paying attention.
- Verify Fishing Regulations: Ensure you have a valid Wisconsin fishing license and check the specific length limits for Lake Wausau, as they can differ from the general state rules.
- Arrive Early: For the best shoreline fishing spots or to secure a first-come, first-served picnic table, aim for a 9:00 AM arrival on weekends.
