At mile marker 135.3 on US Hwy 12, Idaho’s Northwest Passage Scenic Byway, along the Wild and Scenic Lochsa River, a majestic wooden trail bridge forms part of the Eagle Mountain Trailhead, offering hikers, backpackers and those on horseback an opportunity to experience the Selway-Bitterroot Wilderness. Once across the bridge (don’t forget to take some pictures!), the trail follows the river and then a ridgeline as it winds into the wilderness. Hitch rails and some parking are provided at the trailhead.
