Chain O' Lakes State Park

Chain O' Lakes State Park links nine lakes across its landscape, each surrounded by forest and wetland areas that form a connected water system. The park's layout creates a diverse environment where water, trees, and open spaces meet.

The park was established in 1945 as northern Illinois developed and residents increasingly wanted places to spend time outdoors. This creation reflected a growing recognition that public land should be set aside for recreation and nature.

The restored Stanley Schoolhouse on the grounds reflects how rural education worked in early-20th-century Illinois. Walking through this single room shows visitors what learning looked like for families who settled this area.

The park has camping areas scattered throughout and offers miles of trails for walking and exploring on foot. Since the lake system spreads across a large area, visitors should plan ahead to focus on the sections they want to see.

These lakes were carved out by ancient glaciers, leaving kettle-shaped depressions throughout the landscape. To preserve this glacial system, the park restricts boating to electric motors only.
