Southern end is immediately north of the Wassaic Metro North train station in Rt 22. The southern completed section ends at Millerton. There’s then a road detour for 8-9 miles till Under Mt. Road, where the trail picks up again and terminates just north of Copake Falls. I think total distance with the road detour is 23 miles one-way. The section from Wassaic to Millerton is 10.5 miles, all on trail. The road crossings are mostly quiet back roads. Millerton has a nice downtown, deli’s, etc...

More detail here; Harlem Valley Rail Trail ? Wassaic to Chatham or Bust
