NY 9P begins at an intersection with US 9 in Malta. NY 9P proceeds eastward from US 9 as a two-lane residential street through Malta, passing the Bass Manor Museum. The route bends northeastward and soon southward along the shore of Saratoga Lake. At Saratoga Lake, NY 9P intersects with CR 108 (Plains Road) before heading southeast and away from the shore. As the route makes a bend to the north, CR 76 (Lake Road) intersects near the Saratoga Lake Golf Course. At this point, NY 9P becomes a lakeside highway on the eastern side of the lake, passing a long stretch of residences and an intersection with NY 423. After NY 423, NY 9P bends northeastward alongside the lake, now in the town of Stillwater and soon the town of Saratoga.
