Columbia Park is a 19-acre county park located on Lake Winnebago,  about ten miles northeast of Fond du Lac. The park contains a modern 40-unit campground with electrical hookups and restrooms/showers, boat and RV sanitary dump stations, a playground, a basketball court, one enclosed shelter, two open-air picnic shelters, and picnic facilities. 

Columbia Park is probably best known for its boating facilities. A 4-slip marina is available for annual rentals, along with overnight docking for another 40-50 boats on 900 feet of harbor wall.  Six boat launches and parking for 100 cars and trailers, as well as an overflow parking lot are available.  Another popular amenity available to fishermen is a fish cleaning station. 

A 70-foot observation tower and navigation beacon marks the harbor entrance. Columbia Park is watched over by part-time campground hosts. The campground hosts take reservations for campsites, shelters, boat slips, and docking space.
