About Copper Culture State Park

Copper Culture State Park is a small day-use Wisconsin state park located along the Oconto River at the western edge of the City of Oconto in northeastern Wisconsin. The park preserves a nationally significant archaeological site associated with the Old Copper Culture, an ancient Indigenous people who occupied the northern Midwest and used native copper to make tools and ornaments. Excavations at the site uncovered a burial ground with twenty-one burials and a large quantity of copper artifacts, helping researchers understand one of the earliest known metalworking traditions in North America. Today the property functions as a quiet, low-development park with a small museum operated by local partners, interpretive signage, picnic facilities, mowed grass areas, and short walking paths through groves of trees along the river. There is no campground inside the park, so RV travelers typically visit as a day stop while staying at private campgrounds or other state parks in the Green Bay and Bay of Green Bay region.

How to get to Copper Culture State Park

The park sits just west of downtown Oconto, Wisconsin, off US Highway 41/141, roughly a 35 to 45 minute drive (about 30 miles) north of Green Bay and about 3.5 hours north of Milwaukee. Access roads are flat, paved, and free of mountain passes or tunnels, making the route straightforward for any RV class, though the internal park road and parking loop are compact, so larger Class A motorhomes should scout turnaround space before pulling in. Watch for posted local weight limits on smaller side streets in Oconto and use the main highway approach. The nearest commercial airport for fly-and-rent travelers is Green Bay Austin Straubel International Airport (GRB).

Best time to visit Copper Culture State Park

Late May through early October offers the most comfortable conditions for an RV day visit, with mild temperatures, green grounds, and reliable access to the picnic area and interpretive trails. July and August bring the warmest weather and the highest visitation in the broader Oconto and Green Bay area. September and early October are excellent shoulder-season choices, with cooler air, fewer mosquitoes, and fall color along the Oconto River. Winter visits are limited because grounds are snow-covered and the on-site museum is seasonal.

Our family had a great stay in Taylor’s camper! It was clean, well equipped and he was great explaining everything to us when we arrived. We already booked it for next year!

I've rented his rv several times now and will continue to anytime im in the area. Excellent host and very clean and well equipped rv. He makes sure you know how everything works and where it is. He makes setting up and returning the rv is easy and confusion free. If you need an rv definitely look at him first except when I want to rent it of course.
