Mt. Jupiter Trail #809 Professional Reviews and Guides
"This is a long, bone-dry, and at times steep trek to a former ﬁre lookout site atop Mount Jupiter—but the views are worth the effort! Feast on them, from prominent eastern-slope Olympic peaks to Hood Canal, Mount Rainier, and a procession of Cascade peaks. Situated between Mount Constance and the Brothers, Jupiter also provides an eagle’s-eye perspective of the Duckabush and Dosewallips valleys, two of the Olympics’ great green portals into its hinterlands.
Road subject to changes and closures due to logging on adjacent private lands. Road closed for wildlife management mid-Oct–May 1. Do not park in front of the gate."
--Craig Romano, Day Hiking: Olympic Peninsula - 2nd Edition (The Mountaineers Books).
"A 14.2-mile round-trip day hike to the summit of Mount Jupiter. This trail follows a high ridgetop into The Brothers Wilderness, arriving at an old lookout site that commands excellent views of the eastern Olympics. It is the only relatively level trek in the southeastern part of the range that visits the high country. There is no surface water along the route, so be sure to bring a plentiful supply for drinking. Along the way, hikers can look south to view remnants of the 2011 Big Hump Fire, which scarred over 1,000 acres of the Duckabush drainage. The fire was caused by wilderness campers who failed to fully extinguish a campfire."
