Adams County Parks

The hub of summer activity can be found at Castle Rock and Petenwell County Parks, located on the respective flowages of the Wisconsin River. Both offer camping complete with electrical and water hookups, showers, flush toilets, and dump station. Semi-primitive tent sites are also available.

The large, clean beaches, boat landings and visitor hospitality have people coming back year after year. Both Castle Rock and Petenwell Lake can accommodate all types of watercraft, while the river below Castle Rock Dam makes for a most enjoyable canoe trip.

Wintertime is snowmobiling season, currently over 230 miles of state funded, well groomed trails twist through forest and farmland. Afterward, cozy accommodations and dining top off a perfect outing.

Roche-a-Cri State ParkCenturies before it served as a natural landmark along French fur-trading routes, Roche-a-Cri Mound held significance for the area’s earliest inhabitants. The mysterious carvings and paintings on the rock of the south face bear witness to their passing. The archaeological importance of these prehistoric art forms has earned Roche-a-Cri Mound its listing on the National Register of Historic Places.

The 300 foot cambrian sandstone rock outcropping, from which the park derives its name, was once an island in glacial Lake Wisconsin. The summit, now accessible by a stairway, offers a breathtaking 120 mile panorama.

As intended the stairway has served to simultaneously improve public access to this natural monument while helping to protect the park’s environmentally sensitive areas.
The varied terrain of the 425 acre park includes grasslands, open cliffs, pine barrens, oak forest, prairie, and the trout-rippled meanders of Carter Creek.

Roche-a-Cri State Park offers 41 rustic campsites. Of these sites, 37 are reservable, 1 is handicap accessible, 3 are non reservable, and 4 sites offer electrical hookups. Every site includes a fire ring and picnic table. There are 2 toilet facilities and 2 water stations within the campground. Firewood is available for sale at the office. The park has 5 miles of marked hiking trails that also serve cross-country skiers during the winter. In any season, the spectacular scenery is unmatched in beauty.

Friends of the Park sponsors several events at Roche-a-Cri, including the Pumpkin Walk, Candlelight Hike, Breakfast with the Birds, Annual Photography Contest, and various naturalist presentations designed to promote the use and appreciation of this extraordinary natural resource.
