About
Overview
Spread along the banks of the Upper Mississippi River, the Grant River Campground, located in the "Catfish Capital of Wisconsin," is a modern campground that offers a plethora of outdoor and recreational activities.
Recreation
The famous fishing on the Mississippi River draws crowds of anglers each year. The most popular species is the channel catfish, earning the city of Potosi the nickname "Catfish Capital of Wisconsin." Other species include bluegill, walleye, crappie, northern pike and bass. Best to try your luck in the spring before the rice field grows up.
There is boat ramp access within the campground, but can be chalenging for larger vessels as water levels drop and aquatic vegetation grows up.
Facilities
Picnic shelter and a playgrounds create an ideal environment for a small party or family get-together. Both tent and RV sites are available, and amenities like showers, drinking water and flush toilets offer a comfortable camping experience.
Natural Features
Surrounding the large campsite is a lush river landscape with towering bluffs and beautiful sunsets, creating a nature experience for visitors without losing the comforts of modern camping.

Is GRANT RIVER fully booked?
A campground showing no availability is almost never full for good. People cancel — plans change, weather turns, someone books three weekends and keeps one — and the site goes straight back into the booking system, usually without warning and often at odd hours. The reason sold-out campgrounds feel impossible is not that sites never free up; it is that nobody is watching at the moment they do.
CampHawk watches GRANT RIVER in Potosi, WI for you. We recheck it every 15 seconds, around the clock, and the moment a site opens we send a text, an email and a push notification — and on Recreation.gov we can put the site straight into your cart, so it is held while you get to your phone.
Searching is free and needs no account — the calendar above is live right now. Watching GRANT RIVER for cancellations is the paid part.
