The road to Climber's Bivouac is inaccessible by vehicle. The winter climbing route (Worm Flows) out of Marble Mountain Sno Park is the preferred climbing route for winter and spring. A Sno Park Pass is required to park at Marble Mountain Sno Park between November and April and can be purchased online, at local vendors or Forest Service office, or with cash/check at the parking lot (daily permit only, no annual available at parking lot). Dispersed camping is available around the parking lot. There are pit toilets available, but no running water or trash service. Please plan accordingly.

Winter is right around the corner, and on the mountain it has already arrived! The Climber's Bivouac road has enough snow to make it no longer accessible to vehicles. The Marble Mountain Sno Park is the preferred trailhead to begin winter climbs. There are 12-18" of snow at the parking lot, though the road is plowed. With deep, heavy, wet snow covering the mountain, it is a difficult and high risk time to climb and solo adventures are ill advised. Preferable gear includes snow shoes, traction footwear for high elevations, ice axe, and trekking poles with wide baskets. Skins and skis are also a preferable way to go. As snow and rain alternate and accumulate, avalanche risk on steep slopes will increase. Even in snow shoes, powder is hip deep in some places, and provide quite the workout. Be prepared for high winds that bring varying amounts of precipitation. The summit does have a cornice forming, please stay back from the edge!

Please check the forecast as weather conditions as mountain conditions can change rapidly.
