      North Harmony State Forest totals 2,561 acres and provides many outdoor recreational opportunities such as cross-country skiing, snowshoeing, hiking and hunting. It also serves as a source of raw material for New York's forest products industry which provides employment and income for many New Yorkers as well as various habitats for many wildlife species such as deer, rabbit, grouse and turkey.

      The forest is home to Wiltsie Marsh, located just off of Wiltsie Road in the town of Sherman. Also known as Two Ponds, Wiltsie Marsh is a man made marsh that was built with federal funds during the mid to late 1950s. Marsh reconstruction efforts took place in the summer of 2007 to repair beaver damage that occurred on the dike.
