I followed the route created by Ben Nephew and found his description to be highly accurate! The route begins at the Camp Smith trailhead and heads North up and around Manitou Mountain before summiting Anthony's Nose. It then continues down before connecting with the Appalachian Trail for the final stretch to South Mountain Pass Road. The route then reverses back to the start with side trip out to the Anthony's Nose overlook.
Started this at 6pm on a Sunday evening. It was actually quite cool, between 65 - 70 degrees. It was a race to finish before the sun set! Stunning trail with several viewpoints over the Hudson River.
