The Outdoor Discovery Center Macatawa Greenway is a nonprofit environmental education and conservation organization. The ODCMG offers outdoor education and recreation experiences to schools, organizations, community groups, and individuals. Annually, thousands of people participate in a wide variety of natural and cultural history programs and experiences on the 130-acre Outdoor Discovery Center nature preserve, along the 1,000 protected acres of the Macatawa River Greenway, at local parks and natural areas, and in school classrooms. ODCMG programs are customized to fit the needs of each group with a focus on hands-on, inquiry-based learning experiences.
