Across the county line in Lake Luzerne, NY 9N begins to deviate from the Hudson River, gradually curving to the northeast as it passes through the hamlets of Lake Luzerne, Fourth Lake, and Lake Vanare, all of which are named for small lakes bearing those names near the center of the communities. Just northeast of Lake Vanare, NY 9N enters the town of Lake George, where it connects to I-87 (the Adirondack Northway) at exit 21 and meets US 9. Here, it joins its parent route northward toward the village of Lake George. The conjoined routes intersect the northern end of NY 9L just south of the village line before becoming Canada Street and entering the village limits upon crossing over West Brook. US 9 and NY 9N serve as the primary north–south thoroughfare through the village before splitting at the north end of the village. While US 9 continues to the north, NY 9N heads northeast along the western edge of Lake George.
