If the perfect dayhike combines beauty, drama, and moderate physical activity, then a dayhike to the Frisco Box is perfection. The drive to the trailhead is scenic. The walk is pleasantly level. And the 3 mile trek climaxes in a startling box canyon the width of a large living room. Through this room flows the San Francisco River. Craggy rock walls rise above the stream bed, which in many places is also the canyon bottom. Amid this harsh geology, cottonwoods and alders have found a foothold, adding further lushness to the green of Virginia creeper, grapevine, willow, and wild rose.
