We've camped at a couple Wisconsin state parks and have found them very nice with spacious sites. We camped recently at Willow River State Park north of Hudson (this is about 1/2 hour west of Eau Claire) and liked it a lot. I would recommend the 300 campground, not the 100 or 200 (no trees in these). From the campsite we had we could easily walk to the swimming beach and the playground. The 300 campground is heavily wooded. In fact, we would have had a hard time getting to our site with all the trees and the narrow roads if we had a huge camper.
