Website | Reservations | Map

Grassy Lake is a quiet, contemplative site, featuring gently rolling hills, oak woodlands, marshes and moraines.

Trails The preserve's 5.6 miles of gravel and mowed grass trails offer some of the best access to the banks of the Fox River.

Trails here wind through colorful sedge meadows, mature oak woodlands, and a variety of other natural habitats.

Six scenic overlooks offer magnificent views of the Fox River Valley and of Grassy Lake. Kelsey Road divides the preserve's two separate northern sections, but a trail tunnel and an at-grade road crossing with a flashing beacon provide safe passage at both locations.

Trail connections are also provided to adjacent neighborhoods. 4.1 miles of trails are open only for hiking, biking and cross-country skiing. 1.5 miles of trails north of the Kelsey Rd parking lot are open to hiking and cross-country skiing only, biking is not allowed on these trails.

Please keep dogs leashed and on the trails at all times, and pick up after them.

Learn about our off-leash Dog Parks (permit required).
