There are different entry points all along the surrounding towns. If you start in Kerhonkson, the path is partially shaded and you can go out as far as you'd like and come back the way you came. There is a bench just about 1 mile in, meaning you can go there and back for a lovely 2 mile walk.
This is another great ice cream option on Route 209 - they also have food options.
This is on the same little road as the Kerhonkson Rail Trail entrance. If you are looking for a meal in addition to all the wedding festivities, this is a great option.
This is a great ice cream shop right near the Rail Trail. If you're looking for something sweet, this is a great option!
