Mt Washburn Trail, located near Tower-Roosevelt, offers a moderately strenuous 6 mile roundtrip hike. The hike to the top of Mt. Washburn is one of the most popular hikes in Yellowstone. Two trails, each 3 miles (4.8 km) in length, switchback to the summit where expansive views of much of Yellowstone unfold below on clear, summer days. An enclosed observation area allows you to get out of the wind. Bighorn sheep are seen quite frequently during the summer on the upper parts of the trails. Harsh alpine conditions contribute to short growing seasons for the fragile alpine vegetation on the mountain. Please stay on the trails and do not approach sheep or other wildlife to help preserve the wildness of this area.
