Hudson is a very scenic river. North of New York City dramatic cliffs rise on both sides and on top as well as below those cliffs there are trails that are accessible by public transit. Here is my favorite long-distance path along the Hudson river.
121 mile path along east shore of Hudson, from Battery to Beacon, with detours to visit interesting gardens and other points of interest
