I completed this trail as a day hike. It is extremely beautiful. The mileage and strenuous rating are accurate. The path is extremely rocky along the old stagecoach section, and there are boulder scrambles in both directions from the beginning of the loop. This is a really nice hike, but I would recommend less experienced hikers build up to this trail and allot plenty of time for completion. Big Creek Gulf and Rim trails are easier and may be a good test run before venturing this way.
