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. Once out of the village, NY 17A and NY 94 begin to climb again, this time offering some panoramic views to the north, all the way to the
Shawangunk Ridge and even the
Catskill Mountains beyond them in clear enough weather. The road is surprisingly little developed in this area, with only one gas station between Florida and
Warwick, its next stop, which likewise presents itself after a descent. Again, NY 17A and NY 94 serve as the bustling village's main street, longer this time and with many upscale boutiques in evidence. Many
historic buildings line the road through Warwick. Near the southern end of the village, the two roads split, with NY 94 continuing toward New Jersey while NY 17A goes eastward. The road begins to climb again over the next few miles, passing a county park and finally the small
Mount Peter ski area before crossing the
Appalachian Trail along the ridgecrest of
Bellvale Mountain. From here it once again drops down and bends in a north–south direction to reach
Greenwood Lake, where NY 210 leaves to go along the side of the lake to the state line. Leaving Greenwood Lake, NY 17A climbs once again to cross another ridge before descending and expanding to a four-lane
expressway to pass through Sterling Forest and reach its eastern terminus at NY 17 in
Southfields. The highway formerly continued as County Route 106 (CR 106) in
Orange and
Rockland counties east to that route's eastern terminus at
U.S. Route 9W (US 9W) and
US 202 in
Stony Point. CR 106 was once part of
NY 210 before it was truncated to NY 17A in
Greenwood Lake. ==History==
