Tubal Cain Mine and the Buckhorn Wilderness is one of my favorite places to take beginner backpackers. This trail system is packed with a B-17 crash site, mines, mining equipment and trails that lead to some impressive mountain summit views. Camp sites sit below the Tubal Cain Mine along the Copper River, 3.5 miles and 700 feet of elevation gain from the trailhead. The turnoff to climb up hill to check out the crash site is about a quarter mile before the camping area. Follow the trail across the river and traverse across a mountain trail to panoramic views of the Puget Sound and Olympic Mountains.
