Green Mountain Trail   Green Mountain is a fun hike whether you do an out-n-back up the frontside or do a loop and come back via Gregory Canyon. It is approx. 2.5 miles up the front side and you gain almost 2,500 vertical from trailhead to the peak.... so have your lungs ready, the view from the peak are spectacular.
