Grass River Natural Area

Grass River Natural Area is a 1,492 acre nature preserve surrounding the Grass River, located in the heart of Antrim County. Along with the beautiful views of Grass River, we also offer seven miles of well-maintained trails including 1.5 miles of boardwalk floating above northern fen and cedar wetlands. With all of these natural features, Grass River Natural Area offers visitors an outdoor, living laboratory to explore and learn. The Grass River Center is open year-round, offering a comfortable learning environment for public programming, school field trips, camps, and more.
