Flagstaff Lake is part of the Northern Forest Canoe Trail. The Northern Forest Canoe Trail is an historic 740-mile water trail through New York, Vermont, Quebec, New Hampshire, and Maine.
This is a popular three-season recreation area, with spring being the only time when there are few visitors. The Appalachian Trail and other trails as well as fishing, swimming, and camping offer a variety of outdoor activities at the Preserve. Fall foliage can be viewed from the roads and trails. Hunting and trapping opportunities range from easy vehicle access to foot access only in the backcountry areas. Fishing is plentiful in many small ponds and brooks. Winter visitors enjoy snowmobiling and cross country skiing over 20 miles of designated trails.
