More than 75,000 people annually visit ODC Network sites to walk the trails and view the wildlife. With its partners, the organization helps protects over 1,200 acres along the Macatawa River and the Outdoor Discovery Center - a 155 acre nature preserve in Holland, MI. The ODC Nature Preserve is free and open to the public dawn to dusk every day of the year.
