The Treeline is an urban trail connecting the best of Ann Arbor. It will be a defining feature of our geography, providing a common place to explore, bike, run, and reconnect with nature—and each other.
Because of you, 2021 was a year of accomplishments that brought the Treeline ever closer to reality. Learn where the trail lies by reading our 2021 Annual Report.
