An enthusiastic 3 thumbs up...easily the BEST hike we've ever done. Warning: It is a grueling, steep ascent and descent, with moderate rock scrambling. Bring LOTS of water and and PLENTY of snacks, but you can refuel at Greenleaf Hut if you run out. For your suffering and determination, you will be rewarded thousandfold with unforgettable killer views as you hike the ridge of a true alpine mountain range with a totally unobstructed view (you are above treeline). We made frequent stops and did it in a day, the 9 mile loop took us about 9 hours, word to the wise: start EARLY. But you can sleepover at the AMC Greenleaf Hut to turn this into a 2 day hike. We ascended via Old Bridle Path and descended via Falling Waters. In our opinion, Old Bridle Path is far steeper than Falling Waters thus we would not recommend descending via Old Bridle Path. Be careful: Falling Waters can be slippery.
