September 14, 2020 update

Sunrise: 6:49 am

Sunset: 7:19 pm

The road to Climber's Bivouac is OPEN as of June 18. The road to Climber's Bivouac will be in poor condition after winter storms, and drivers should take extra caution and drive slowly. Climbers may also choose climb out of Marble Mountain Sno-Park (winter route).

There are pit toilets available at both trailheads, but no running water, and bathroom services may be limited so please bring your own toilet paper, soap, water, or hand sanitizer. Please plan accordingly. A pre-purchase climbing permit is required and climbers must register in the log book at the climber's kiosk before climbing.

Please climb with your quarantine household, and maintain at least 6 feet of space between yourself and other hikers. Please review our Mount St. Helens and COVID-19 page to learn about open trailheads and sites, expected services, and how to recreate responsibly. Consider bringing a mask to put on when you pass others on the trail.

SUMMER ROUTE, MONITOR RIDGE out of Climber's Bivouac:

The road to Climber's Bivouac is recently compacted and drivers should take extra caution and drive at a slow, consistent speed. Consider down shifting when heading downhill to avoid braking, which causes washboarding. A NW Forest Pass, America the Beautiful Pass, or day-use pass (available at the trailhead for $5 cash or check), is required to park at Climber's Bivouac. There is no snow through the woods up to the crossing of the Loowit Trail #216 at Last Chance Bathroom. The bathroom is OUT OF SERVICE and climber's are required to utilize blue bags to pack out all human or pet waste. Above treeline, the ridges are melted out entirely, and climbers can ascend the entire route on rock. The true summit is 1/4 mi west of where the route tops out. On the descent, soft snow persists in the gullies with a few icy patches. Do not just follow the "fall-line" on your descent. Route finding may be challenging in dense cloud or fog; be sure to know the route and carry navigation equipment.

No glissading or skiing, so microspikes, crampons, and ice axes are unnecessary at this time. Hiking boots with gaiters are fine. Snowshoes, crampons, and mountaineering boots are not necessary at this time.

Please check the forecast as conditions can change rapidly.
