Since the 1920s, North Chagrin Reservation has been a special combination of outdoor recreation areas and wildlife sanctuaries. An interesting feature of the reservation is Squire's Castle. Built at the turn of the century by F.B. Squire, it was to serve as the gatehouse of his country estate, but plans for the remainder of the estate never materialized.
Located in Mayfield Village, Willoughby Hills, and Gates Mills, the reservation includes a nature center and nature education building, a number of trails and picnic areas. Sanctuary Marsh and Sunset Pond are both popular areas to observe waterfowl. The reservation is also home to Manakiki Golf Course, located off SOM Center and Eddy roads in Willoughby Hills.
