Jean and John Greene Nature Preserve

Lake Forest Open Lands’ Jean and John Greene Nature Preserve encompassing 61 acres contains three ravines: McCormick Ravine, Deromedi Ravine and a portion of Janes Ravine.  The trails in the Preserve, including an all-access trail to Duckworth Point, offer year-round access to Lake Michigan and opportunities to explore this unique ecosystem. 

The Preserve contains rare ravine, bluff, and lakeshore natural communities, which are home to seven state endangered and threatened native plant species and provide important resting habitat for migratory birds along the Lake Michigan flyway.

Because of the highly sensitive nature of the rare plants, many of which are found directly off the trail, it is important that all visitors stay on marked trails, bicyclists park their bikes at the designated bike rack and no dogs are allowed.

Thank you for helping us preserve this special place!
