A popular watchable wildlife area, Mueller is home to abundant wildlife including elk, black bear, hawks, and mule deer. Visitors can enjoy year-round recreational opportunities including camping, picnicking, trail use, fishing and nature studies.
Winter activities include sledding, snowshoeing and cross country skiing. Mueller State Park welcomes leashed pets in campgrounds, picnic areas and on the paved roads, but not on the hiking trails or in the backcountry.
