East of Eagle River, the Anvil National Recreation Trail system has 12 miles of groomed loops. This is one of the oldest and most popular cross-country ski trails in the Eagle River area. Trails are groomed for traditional style-skiing as well as ski-skating. Several loops are available over varied terrain from easy to difficult. Originally constructed in the 1930s by the Civilian Conservation Corps, the system has since been expanded and was made part of the National Recreational Trail System in 1978. The Anvil Trail system is adjacent to Anvil Lake Campground and also connects with the Nicolet North Trail system and to the Franklin Lake Campground via a connector trail.
