getting there

Drive US-101 to the Dosewallips River Road, just north of Brinnon. Turn onto Dosewallips River Road and drive just over 9 miles to where the road is washed out and park there.


Hike a trail around the washout and continue hinking on the road to the Ranger Station, 5.6 miles. Mountain bikes are a good time-saving option for this section of travel. From the Ranger Station (1,600 ft), take the Dosewallips Trail 1.4 mi to the junction with the West Fork Dosewallips Trail. Take the West Fork Trail to Honeymoon Meadows camp (3,527 ft), 8 mi from the Ranger Station. The Anderson Pass Shelter, located 0.7 mi and 700 feet of elevation gain beyond Honeymoon Meadows, is an alternate campsite. Continue on the West Fork Dosewallips Trail 1.2 mi to Anderson Pass (4,464 ft). Turn right on a trail and ascend to the Anderson Glacier moraine (5,200 ft). Cross the moraine and drop onto the glacier. Rope up here.


Follow the right side of the glacier to the steep snow finger below Flypaper Pass. Ascend this snow finger to the pass at 6,500 ft. From Flypaper Pass drop 200 feet onto the Eel Glacier and traverse around a rock buttress. Then climb E on the upper Eel Glacier to a saddle just north of the summit. Follow snow and rock south to the summit.


Descend the climbing route.
