    Directions to Trailhead

    Forbidden Peak is one of Washington’s 100 steepest climbs, and it is a Class 5 climb only recommended for those with mountaineering experience and the proper gear. The horn-shaped summit offers remarkable views in all directions, and each ascent approach offers great rock quality. The West Ridge is the most commonly climbed route, likely due to its inclusion in the 50 Classic Climbs in North America.
