Lakewood is Lake County's largest forest preserve. Dedicated equestrian trails, and additional trails for hiking, cross-country skiing and snowmobiiling. No bikes and no dogs. Lakewood is home to 24 threatened and endangered species. On the west side of the preserve is the 70-acre Wauconda Bog. It is ringed by poison sumac and a natural moat, and is so ecologically valuable it is designated as a National Natural Landmark and an Illinois Nature.
