Monitor Ridge Climbing Route
The Monitor Ridge Climbing Route is the primary route used by climbers during the summer to reach Mount St Helens Summit. It is a non-technical scramble, gaining 4,500 feet in 5 miles. Most climbers complete the round trip in 7 to 12 hours.
The climbing route used in the summer months begins at Climber's Bivouac south of the volcano. At 3,700 feet elevation, Climber's Bivouac has the highest vehicle access on Mount St. Helens. Start on Ptarmigan Trail #216A which climbs 1,100 feet in 2 1/4 miles to timberline at 4,800 feet elevation.
Above timberline, the route generally follows Monitor Ridge, climbing steeply through 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.
