Nelson Dewey

Overview

Nelson Dewey State Park offers a unique blend of Wisconsin history and natural beauty. Named after the state’s first governor, this park is perched high on limestone bluffs overlooking the vast Mississippi River. Visitors will find a peaceful atmosphere characterized by quiet woods and expansive views of the river valley. It serves as a gateway to the region’s past while providing modern travelers with a serene environment for relaxation and exploration. The park spans several hundred acres of diverse terrain, making it a standout destination for those traveling through the Upper Mississippi River Valley.

Location & Surroundings

Situated just outside the village of Cassville, WI, the park is part of the scenic Driftless Area. This unique geological region is defined by rugged hills and deep valleys that were untouched by glaciers. The park’s position atop the bluffs provides some of the most stunning vistas of the Mississippi River, where you can watch tugboats and barges navigate the winding water below. The surrounding landscape is dominated by lush hardwood forests that provide a vibrant canopy, offering a cool retreat in the summer and brilliant colors during the autumn months.

Amenities & Park Features

The campground at Nelson Dewey State Park provides a range of options for RVers, including several sites equipped with electric hookups for added convenience. While the park maintains a rustic, natural feel, it offers essential comforts such as a dump station, fresh water access, and a central shower building with flush toilets. RVers will appreciate the well-maintained wooded campsites that offer a sense of seclusion and privacy. Additionally, the park features multiple picnic areas and reservable shelters that are perfect for outdoor gatherings overlooking the river valley.

Nearby Attractions & Things to Do

Directly adjacent to the park is the Stonefield Historic Site, which includes the original estate of Nelson Dewey and a recreated 1900s farming village. Nature lovers can explore miles of hiking trails that wind through the bluffs, prairies, and oak savannas. A short drive away, the Cassville Ferry offers a rare chance to cross the Mississippi River to Iowa on a seasonal car ferry. Birdwatchers frequently visit the area to spot bald eagles and other migratory birds, which are common along the riverbanks throughout the year.

Who This Park Is Best For

This park is an ideal destination for history buffs and nature enthusiasts who prefer a quiet, slower pace of travel. It is perfect for RVers who enjoy birdwatching and photography, as the high elevation provides incredible perspectives of the river. Families will appreciate the educational opportunities at the nearby historic sites. If you are looking for a scenic retreat away from the bustle of commercial resorts, this state park offers the perfect blend of solitude, heritage, and outdoor recreation.

Quiet park with a good variety of short trails. The only negative is the trains. Showers are pretty nice with tile. Drinking water is very clear. Woodshed is open 24/7. Carts are available for the walk in sites.

Beautiful place! Campsites have a gravel pad. Various sizes. The views are gorgeous! Campground did not have a host while I was there but did have an "on your honor" area to buy wood/ice/fire starters. Also a soda vending machine. This was open 24 hours a day (which I appreciated!) There is a mix of plumbed bathrooms with showers and pit toilets. A train runs nearby but the cicadas in August drown out the sound of it. There are Indian mounds and a shelter. The office was not open when I visited. There are nearby historical places. LOTS of flies and mosquitoes in August 2025! One short paved trail. The other short trails were not stroller or wheelchair/walker friendly. Would recommend!

Oh, wow, what beautiful views! You can drive right into the park (after paying a fee) and straight up and around a large bluff that overlooks the Mississippi River. We stopped by on our way from East Dubuque to Prairie Du Chien and we're so glad we did! We hung out for about an hour and absorbed the view and basked in the sounds of nature. There was hardly anyone else there and about half the time we had the overlook completely to ourselves. This is definitely a hidden gem!

Stayed 9 days early spring, very nice. If you like bird watching this is a place you should go. Good dump and water fill ups at the top of the park, some sites are a little challenging for larger RV’s. Hiking trails are fun and fairly easy, some a little challenging just take your time. Would camp here again. It’s an absolute must check out the overlooks at sunset.
