Mt. Jupiter Trail #809

Area Status: Unreachable

This 7.2 mile trail begins in second growth forest and rhododendrons with brief glimpses of Duckabush valley and Mt. Jupiter. Once past The Brothers Wilderness boundary at 5.5 miles, trees thin out and ridge top provides fantastic views of The Brothers and Puget Sound. Grades are moderate to steep.

This trail switchbacks steeply to the ridge, then gradually follows the ridgeline to the Wilderness boundary where the tread becomes rough and steep. Beyond the Wilderness boundary are views of Mt. Constance, The Brothers, Hood Canal and Jupiter Lakes. There are panoramic views of the Olympic Mountains and Puget Sound from the summit of Mt Jupiter. The best views of Mt. Rainier, Adams, and St. Helens are seen on the return hike. Note: Routes to Jupiter Lakes are not formally established and hikers must scramble down from the ridge 900 feet in elevation to the lakes.
