This is ONE of the BEST hiking trails in Colorado. The description says its an out and back but you can turn it into a loop trail by connecting it with Mill Creek Trail and back down to Highway 145 and back to Telluride. Great chance to see herd of Elk high up in the alpine meadows. If you want to get away form people and the crowds, this is the trail. Once you get up above Pack Basin, the crowds drop out. Cross over the pass into Mill Creek Basin and be sure to rest at the pass for incredible views. Once you start to descend Mill Creek Basin be sure to stop and enjoy the waterfall right about tree line. And you get terrific views across the valley to Mt. Wilson plateau.
