We'll hike from Realization Point to Green Mountain via the Ranger and E.M. Greenman Trail Loop. We'll settle into a steady pace on the way up, with just a few quick stops if needed. Once we reach the summit, we'll take some time to relax and enjoy the views before heading back down. This hike is best for those who enjoy a steady climb and are comfortable hiking without frequent breaks.
