Cuba Marsh has 782 acres dedicated to preserving a natural environment for a host of wetland species, including pied-billed grebes, American coot, American bittern, and king rail.
From the Lake County Forest Preserve District's website:
It would be hard to find a prettier blend of marsh, woodland and grassland in Lake County than that found here. Escape for an hour or so to this quiet oasis to re-energize your mind and body.
Enjoy this clean and safe preserve, and travel three miles of crushed-gravel trail through open areas of gently rolling hills that feature views of the marsh and scattered groves of trees.
A 0.9-mile gravel trail winds from the southern loop of the main trail through the southwest corner of the preserve to Barrington's Citizens Park. This trail segment includes the District's longest boardwalk and the Keith Peterson Bridge. An anonymous donor contributed $100,000 toward the cost of the 50-foot timber bridge for the trail connection as a memorial to the former Forest Preserve Board member (District 5;[masked]), devoted naturalist and outdoorsman.
