NY 17A begins just south of NY 17 exit 124 in the village of Goshen. At the traffic light with the southern on-ramp from NY 17 eastbound, NY 207 becomes NY 17A. The route quickly climbs to some of the hillier areas south of Goshen, offering views of not only Orange County's Black Dirt Region but Pochuck Mountain and High Point to the south in New Jersey. It then slowly descends past rolling meadows and farmland until it reaches the small village of Florida, where NY 94 comes in from the west shortly after the village border. The concurrent roads then become Florida's main street.
