The best option for cross-country skiing is the Ly-co-ki-we Trail. The 6.4 mile trail is a series of interconnecting loops through gently rolling wooded dunes. This trail can be accessed from either the Calumet Dune Interpretive Center (old Dorothy Buell Memorial Visitor Center) or the nearby Ly-co-ki-we Trailhead parking lot. The 3-mile Inland Marsh Trail is a good choice for advanced skiers. There are some difficult hills that can be tricky to navigate. A six-inch snow base is recommended for skiing. Trails are not groomed.

Hikers and visitors using snowshoes are asked to walk to the right of the cross-country ski tracks whenever possible.

Sledding and snowmobiling are not permitted.

Shelf ice often forms along the edge of Lake Michigan during periods of cold weather. Don’t be fooled! Despite its appearance, the shelf ice is not solid. In fact, due to the way it is formed, the shelf ice has numerous air pockets. It can be difficult to tell where the ice ends and the beach begins. Don't walk on the shelf ice! A person applying even a small amount of weight on the ice can easily fall through and into frigid water that can quickly kill. Enjoy the beautiful and unique ice formations from the safety of solid ground.
