Grant Woods Forest Preserve is a 1,200-acre site in Lake County, Illinois, managed by the Lake County Forest Preserve District. The landscape consists of a diverse mix of hardwood forests, wetlands, and restored tallgrass prairies. Visitors can access a network of nearly 6 miles of trails suitable for hiking, cross-country skiing, and snowmobiling. The preserve serves as a significant drainage point for the surrounding watershed, featuring various ponds and marshes. It is primarily used for wildlife observation, with habitats supporting deer, wild turkeys, and numerous migratory bird species. The site is divided into two primary access points: the north entrance off Monaville Road and the south entrance off Fairfield Road.
The elevated ridge overlooking the central marshland provides the most expansive view of the preserve’s varied canopy.
Bring waterproof boots if visiting after heavy rainfall, as sections of the lower trail system are prone to mud.
Check the Lake County Forest Preserves trail map before starting, as some paths are shared between hikers, equestrians, and snowmobilers.
Apply tick repellent during warmer months, as the dense brush and tallgrass areas are common tick habitats.
Do not wander off-trail, as the preserve contains areas of thick brush and potential poison ivy growth.
Open daily from sunrise to sunset; snowmobile trails are only available when ground conditions meet state safety requirements.
Leashed dogs are permitted on trails; stay on marked paths to protect sensitive prairie restoration areas.
