This program begins with a brief indoor program on winter and the use of snowshoes before a ranger-led snowshoe hike through the fields and woods surrounding the center. Snowshoes will be provided if needed, but a limited number are available. If there is not enough snow, a nature hike will be offered instead. The hikes runs from 1 to 3 p.m. Sunday at Indiana Dunes Visitor Center, 1215 N. State Road 49, in Porter. Other dates include Jan. 28, and Feb. 3 and 17.
