Located just below the Grand Teton, Disappointment Peak is named as such when climbers in 1925 were attempting to climb the Grand, but found an impasse on this peak where a 450 foot drop is encountered to the saddle between the two summits. This route is a great hike that can be done without any technical gear in the summer months. The route hikes through Lupine Meadows and then follows the Valley Trail for and the well-maintained Amphitheater Lake trail. Be aware to go around the left of both Surprise Lake and Amphitheater Lake and then just after Amphitheater, turn to ascend the ridge to the summit. Amazing views of the Tetons are seen along the hike, and from the summit, the view is just below the Grand and is remarkable. Equipment is necessary through snow and ice travel.
