Columbia Park is a 19-acre county park located on Lake Winnebago in Malone, about ten miles northeast of Fond du Lac. The park contains a modern 40-unit campground with electrical hookups and restrooms, boat and RV sanitary dump stations, a playground, a basketball court, one enclosed and one open-air picnic shelter, 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 are available. A 70-foot observation tower and navigation beacon marks the harbor entrance.
