Derwen Mawr Nature Preserve

Open Lands' purchase and a generous land donation completed the assembly of this 26-acre preserve in 1994. Derwen Mawr contains several remnant pockets of original prairie and wetlands. In 2001 Open Lands began to restore the more highly degraded areas of the preserve, removing non-native vegetation and reseeding large sections with native plants. Derwen Mawr connects to and is part of the Skokie River Nature Preserve.

To walk the trails at Derwen Mawr, park at Deerpath Middle School and cross Deerpath at the intersection with Golf Lane. Walk east to the gated trailhead and kiosk. No parking on Deerpath or Golf Lane.
