About

Spread along the banks of the Upper Mississippi River near Potosi, Wisconsin, Grant River Campground is a modern Army Corps of Engineers facility that combines natural beauty with comfortable camping amenities. The campground offers 73 sites total, with 63 large RV sites featuring electrical hookups and 10 tent-only non-electric sites. The campground is renowned for fishing on the Mississippi River, drawing crowds of anglers each year. Channel catfish are the most popular catch, earning Potosi the nickname "Catfish Capital of Wisconsin." Other species include bluegill, walleye, crappie, northern pike, and bass, with spring offering the best fishing before aquatic vegetation grows up. A boat ramp provides water access, though it can be challenging for larger vessels as water levels drop and vegetation increases. Surrounding the campground is a lush river landscape with towering bluffs and beautiful sunsets. Amenities include flush toilets, showers, drinking water, a dump station, picnic shelter, and playground. The campground operates as a self-service facility where campers can modify reservations through Recreation.gov.
