Columbia Park is a 19-acre county park located on Lake Winnebago at N10340 Calumet Harbor Rd., 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.
Columbia Park is watched over by part-time campground hosts. The campground hosts take reservations for campsites, shelters, boat slips, and docking space.
Past improvements at Columbia Park include a drainage system, boat launches, renovation of the harbor wall, two expanded and repaved parking lots, a pit toilet, a renovated bathroom with showers, connection to sanitary sewer, the construction of a shelter, landscaping and extensive boat facility improvements. These include an overflow boater's parking lot, 400 feet of additional transient and overnight dock space, dredging of the main harbor channel and a sanitary dump station for boaters and another for RVs. A fish cleaning station was constructed during the summer of 2016.
