Big Eau Pleine Park Campground

Anglers and water enthusiasts will find plenty to explore at Big Eau Pleine Park Campground, where 106 sites spread across two units on a peninsula jutting into the Big Eau Pleine Flowage. Marathon County operates this 1,450-acre park with mixed hardwoods and direct water access through three boat launches.

The campground divides into West and South units, with about 60 sites offering electric hookups. Sites range from $18 for non-electric without lake views to $23 for lakefront electric sites. "Sites have a little bit of trees between for privacy," notes Nicole H., though campers consistently mention the family-friendly atmosphere during peak season. The handicap-accessible site near restrooms provides extra space for both RVs and tents.

Twelve miles of trails wind through the wooded peninsula for hiking, biking, and horseback riding. The park features a disc golf course, swimming beach, and multiple fishing spots near the entrance and boat launches. Walter W. found "lots of wildlife" along the trails, while fishing remains popular despite seasonal algae affecting water quality. Firewood permits cost extra and are only sold between 8am-8pm daily.

Water conditions vary throughout the season, with green algae blooms affecting swimming and fishing quality during warmer months. The campground operates from May 2 through October 31, with reservations available. Cell service reaches most sites, with Verizon users reporting three bars of LTE coverage. Campers exploring the region can find campgrounds near Mosinee for additional options.

The concrete restrooms double as weather shelters during storms, and the group site includes covered picnic areas with electric hookups for larger gatherings.

Many campers appreciated the large, level sites and family-friendly activities like trails, swimming, and disc golf. Some feedback indicated issues with restroom lighting and strict rule enforcement, though most found good value at this county park.

Water quality issue Large group site

I have camped with a club in the group site for years. Electric sites. No water. You now pay to dump your waste. Price is right for a county site. BUT the water quality suffers from green algae almost the entire season. Fishing can be good. No longer good for nocturnal carp due to water. Group site is still a good deal. They’ve added electric for at least 8-10 campers. Big site. Your own covered picnic area. There are concrete outhouses which we have used as bunkers during inclement weather.

No longer a nice campground

Been coming here for years. But the rangers and camp hosts will give you tickets for EVERYTHING. I was profiled for fitting the description of a vehicle they had an issue with the week prior and I got a $50 ticket! My campsite was filled with nails and wood staples and the coals in the fire pit were overflowing. There’s no guest parking anywhere near the campsites and they’ll write you a ticket if you park by the bathrooms or have more than 2 cars in your site.

This park offers 12 miles of trails, scenic beauty, wooded sites and more!

This gorgeous county park in Marathon County, Wisconsin is 1,450 acres of mixed hardwoods forming a two-mile peninsula jutting out deep into the waters of the Big Eau Pleine Flowage.

Eau Pleine is from the French phrase meaning full water or stock river. There are two separate campgrounds–( the West Unit and the South Unit) with a total of 106 sites– about 60 with electric. The daily fee ranges from$18.00 for a non-electric, with no lake view to$23.00 for lake view with electric.

You can hike, bike, or ride your horse on the 12 miles of scenic, wooded trails. The park also offers several fishing points near the entrance and along the three boat landings. There is also a beach, two shelters and scattered picnic areas. And you can enjoy a fun game of disc golf on the scenic wooded course.

We found this park to be absolutely beautiful and definitely give it a double Hell Yeah!!

Good Family Campsite

Firewood permits are required and only sold from 8am - 8pm The permit lasts for one day and can only be purchased from one locatIon.

Sites have a little bit of trees between for privacy. Lots of families. Lots of stuff to do. Nice traIls and single-track. Heads up there is a daily fee for disk golf course.

For those requiring cell service, i had 3 bars LTE with Verizon at my site.

Two stars for the firewood hours and privacy (I prefer more between my neighbors and I). Also, not sure about swimming in the water as there was neon green (greener than Chicago River on St. Pats) stuff washed up on the beach.
