Located on the far western edge of Wisconsin this state park offers a little of everything - hiking trails connected to the camp grounds, boat access to the Wisconsin and Mississippi Rivers, overlook of where the Wisconsin River meets the Mississippi River, showers and flush toilets, playground/basketball/tennis courts, etc. Depending on what part of the park you are in (and the season) you can be away from it all or have almost all the comforts of home. There are 2 campgrounds within the park - Homestead (back in the woods and a little more rustic with vault toilets and no showers) and Ridge (on the bluff). Also both an indoor group site and outdoor group site. Campsites are mix of RV (+/- electric) and tent. Ridge Campground sites- located on the bluff they stay dry even when the rivers are at flood level. Some sites have views of the river right from the tent/RV. During peak season you will definitely need a reservation (likely months in advance), but there are a few same day spots held in reserve. Also during peak season there is a concession stand near the campground and boat rental (canoe/kayak) near the boat launch (neither were open when I camped there but were on a separate day trip)

A short drive from the state park is Effigy Mounds National Monument with additional trails and a reverse of the scenic view (looking south and east instead of west/northwest). Definitely worth a look since its FREE and so close by. Also in the area is Villa Louis (historical homestead) which can be toured for a modest fee (good rainy day activity). If coming from Madison area be sure to check out some of the small wineries along the drive either to or from the park.
