At this point, NY 431 curves to the south, climbing up the western side of both Esther Mountain and Whiteface Mountain. Upon reaching in elevation, a large building at the top of Whiteface Mountain called The Castle becomes visible, and Union Falls Pond can be seen more clearly below. The scenic drive continues up Whiteface Mountain to its summit, which NY 431 ascends toward by way of a pair of hairpin turns just north of the peak. At the first of the turns, the highway reaches an overlook in elevation that provides views of parts of Lake Placid and the Olympic Village. The road and the NY 431 designation both terminate at a parking lot about below the summit of Whiteface Mountain, where The Castle is located.
