The approach starts on WA state route 20 at the Easy Pass Trailhead. An elevation gain of about 3200 ft in 3 miles is followed by a loss of 1500 ft into the Fisher Creek drainage. Two miles of off trail hiking, including a steep snow couloir, bring climbers to a bivi site at Silent lakes (elevation 7000) and an elevation gain of another 2000 ft. A long climb day includes a traverse across the west face of Arriva to the SW ridge and a scramble up the ridge to the summit. Descend the route.
