Big Eau Pleine County Park
Overview
Big Eau Pleine County Park offers a tranquil escape within the expansive 1,450-acre woods of Marathon County. Situated on a massive peninsula, this park provides a unique opportunity to camp surrounded by water on three sides. The atmosphere is decidedly rustic and peaceful, focusing on the natural beauty of the Northwoods landscape. It is widely recognized for its extensive trail system and access to one of the region's largest reservoirs, making it a favorite for outdoor enthusiasts seeking a quiet retreat from modern distractions.
Location & Surroundings
The park is positioned just southwest of Mosinee, Wisconsin, making it easily accessible yet tucked away from highway noise. Its primary feature is the Big Eau Pleine Reservoir, a 6,800-acre body of water that defines the park’s geography. The surrounding area is a mix of dense hardwood forests and open water views. Visitors will appreciate the secluded peninsula setting, which creates a natural buffer from the outside world, allowing for dark night skies and plenty of local wildlife sightings throughout the year.
Amenities & Park Features
RVers will find two distinct campgrounds providing a mix of electric hookup sites and primitive options for those who prefer off-grid stays. The park includes essential facilities such as a sanitary dump station and fresh water access for convenience. Beyond the campsites, the park features multiple boat launches, a swimming beach, and a professional-grade disc golf course. For those traveling with horses, there are dedicated equestrian trails, while the wooded hiking paths offer miles of exploration for guests looking to stay active during their trip.
Nearby Attractions & Things to Do
Fishing is the main draw here, with the reservoir known for producing trophy-sized musky, walleye, and northern pike. If you venture outside the park, the city of Wausau is a short drive away, offering cultural stops like the Leigh Yawkey Woodson Art Museum. Nature lovers can also explore the Rib Mountain State Park, which provides breathtaking panoramic views of the Wisconsin River Valley. During the winter months, the area transforms into a hub for cross-country skiing and snowmobiling, extending the park's utility across seasons.
Who This Park Is Best For
This park is an ideal match for travelers who prioritize nature and solitude over resort-style luxuries. It is perfect for families who enjoy active vacations centered around fishing, boating, or hiking through deep woods. Large groups and equestrian campers will find the spacious layout and specialized trails particularly accommodating. If you are an RVer looking to disconnect and immerse yourself in an authentic Wisconsin wilderness experience, this park provides the perfect backdrop for your next adventure.

I stayed at the park for the first time in 25 years. It's still beautiful. Camped the west unit. Area was spacious and clean. The water fill at the ranger station is slow! 30 to 45 minutes to fill. Walking trails, horse trails and disk golf are great, very well kept. If you are going to mountain bike, they looked at little grown over, early in the year might be different. All in all it's a very nice facility. Outstanding service Marathon County Parks and Rec.

Held a family wedding in the pavilion on the west side. It's was magical. After the torrential rain and severe thunderstorms moved out the sunset was beautiful. The pavilion itself needs alot of work and some major cleaning. The bathrooms were surprisingly clean but lighting would be a welcome improvement. Overall it was a pleasant experience and many amazing memories were made.

Awesome park, has a ton of horse, walking and bike trails with a bunch of campsites and places for fishing. I saw a bunch of wildflowers and critters

This is one of my favorites to camp at. There's been a lot of rain so some things are a little flooded right now. The bathrooms are pit toilets but are very clean! It's a quiet Campground and has a great beach. Lots of hiking trails and horse riding trails

Haven't been here since before I moved to Florida. Not sure why it took me 8 years to get here since moving back. This is a big, gorgeous park. There is a lot of beach here, plenty of places to fish from and put boats in, many shelters, grills, restrooms, camping areas, and a playground. Even though we came late in the year (the Mead side of the lake seemed to have lost the majority of its leaves already), the views were still outstanding. Didn't see any deer, but there were plenty of birds and small critters running around. This park is well worth visiting. There is currently a pretty bad blue-green algae bloom. If you bring a dog, make sure to keep them away from the water. There are a few Pokestops spread throughout the park. We did not see any gyms. We had very weak signals here, though.
