One of the Centennial Mountains on the border of Idaho and Montana, Mount Jefferson is 10,203 feet high. The peak can be reached by a trail that begins just off the Sawtell Mountain Road; the trail is approximately 4.5 miles in length and has an elevation gain of 1,200 feet. The mountain is best climbed during the summer, but the south side of the ridge is suited to winter hiking. The access road is not open to the public during the winter months, so visitors will have to walk, ski, or snowshoe several miles from the gate to the trailhead.
