One of the most popular outdoor activity in Jefferson County is snowmobiling due to the abundance of snowfall the area receives each year.  Another favorite activity is boating due to Lake Ontario, plus the St Lawrence River as well.  Hiking, snowshoeing, cross country skiing are all popular especially in Winona State Forest, Tug Hill State Forest and Robert Wehle State Park.
