Great hike - I hiked solo today and went up Falling Waters, along the ridge and down old bridle Path, which I think is the easier way to go because of how steep Falling Waters is (couldn’t imagine it helps the knees). If you like trail running, I imagine that Bridle path is a good trail for that - I had blast jumping/jogging over and dodging rocks on the way down. Beautiful view of mountains in every direction. I’m in my 20s, pretty good shape, finished in 5 hours 40 minutes including some 10-15 min breaks on Haystack, Lafayette and at Greenleaf. Arrived at 9am and the parking lot was about 60% full.
