Nelson Dewey State Park is located about 1 miles north of Cassville Wisconsin in the Southwestern corner of the state on the border of Wisconsin and Iowa. Across the street from the park is The Stonefield State Historic Site which is worth checking out if your visiting the park. This park is a quiet park and offers spectacular overlook views of the Mississippi River and wonderful hiking trails. When entering the park you will check in with the small but welcoming park office. This road will take you straight to the campgrounds! The group campground is on your right before just before the long climb up to the family campground and walk in sites. The group camp is primarily open camping with some trees but I would say these are some of the smaller group camps I have seen. There are pit toilets and multiple water stations on the grounds. As you climb up the hill and make it to the top, you will either take a left to the lookout areas or right toward the family campground. The family campground does have 4 walk-in sites also. I prefer to camp the 24-31 loop but I can't say this park offers the best campsites. The restroom were recently remodeled and are modern an welcoming especially the showers. The showers are in the same building and room as the restrooms but don't let that discourage you, there is still privacy. To sum this campsite up, it is smaller than its northern sister park, Wyalusing, but on a much smaller scale and much less to do. There is no boat launch or swimming and other than flush toilets and showers this campground offers the minimal. If you like small, quiet and camping this park is perfect. Just bring what you need as there is not much in the area for necessities.
