The Monitor Ridge Climbing Route is the primary route used by climbers during the summer. It is a nontechnical scramble, gaining 4,500 feet in 5 miles. Most climbers complete the round trip in 7 to 12 hours.
Above timberline, the route generally follows Monitor Ridge, climbing steeply through blocky lava flows and loose pumice and ash. From timberline the route is marked with large wooden posts to about 7,000 feet elevation. The upper 1,300 feet of the route is unmarked and covered with loose, rock, pumice and ash. On your descent, take care to stay on route, a minor detour may put you far off route at timberline.
