Hiked top to bottom, FR #231 crossing to Call of the Canyon trailhead, around 14 miles in about 8 hours. Its always cool to watch how these canyons change over the descent, with the walls rising up, the changing rock layers and vegetation, the creekbed going from dry to isolated pools to a trickle to a pleasant flow. The upper end of the canyon may be less spectacular than the lower, but it still has many nice sections, not to mention NO CROWDS! The half dozen swims / deep wades were brisk but not brutal. Tons of yellow columbine and other flowers the whole way.
