Nestled in the hills of Antrim County in Michigan's northwest corner of the lower peninsula, the Grass River Natural Area (GRNA) encompasses lakes, a meandering river, rushing streams and crystal clear creeks — a haven for plant and animal life, including both rare and endangered species. This natural area project lies midway on the renowned Chain of Lakes waterway, a connector of Torch and Clam lakes, and Lake Bellaire. Grass River Natural Area is open seven days a week from dawn to dusk. Stop by to see what’s happening at the Natural Area, peruse the informative displays, and browse the bookstore. Educational classes for children, adults and school groups, emphasizing the environment and water and land protection are at the core of the popular outdoor curriculum. A network of trails with observation platforms and boardwalks traverse an educational area providing easy access to upland, wetland and aquatic habitats. A portion of this seven mile system is wheelchair and stroller accessible. Grass River Natural Area is publicly owned and managed by a local volunteer board of directors dedicated to water and land protection and environmental education. Visitors are welcome year-round from dawn 'til dusk. GRNA is free to visitors, who are encouraged in return to become volunteers and contributors.
