Just finished hiking this forested trail. Pleasant hike but there is a significant number of up and downs which will leave you winded. This is not a flat trail by any means and your legs will get a fairly good workout. Fair number of mountain bikers who were very courteous. The Tafoni sandstone was beautiful and there is an observation deck. We got there at 10:45 on a Sunday morning so there were not many hikers and the weather was moderate. Did not finish the entire loop as my wife and I were fairly exhausted.
