Rib Mountain State Park

This billion-year-old hill is one of the oldest geologic formations on earth. Rib Mountain State Park is a premier day-use facility with picnicking, hiking trails and a reservable amphitheater. The top of the 60-foot observation tower offers spectacular views of the Wausau area and Wisconsin River. Granite Peak Ski Area is on the north face of the mountain and offers downhill skiing and snowboarding during winter.
