New York State Route 23A (NY 23A) is an east–west state highway in Greene County, New York, in the United States. It serves as a 34.56-mile (55.62 km) alternate route of NY 23 through the northern Catskill Mountains. The route passes several of the Catskill High Peaks, including Hunter Mountain, before dropping into the Hudson Valley via Kaaterskill Clove and ending at an intersection with U.S. Route 9W (US 9W) in the village of Catskill. NY 23A was assigned in the mid-1920s and has not been changed since. A portion of the route through Kaaterskill Clove was closed for several months in 2006 after landslides triggered by heavy rains damaged the route.
NY 23A begins 1 mile (1.6 km) southeast of the hamlet of Prattsville at a three-way junction with NY 23 in the town of Prattsville. NY 23 enters the intersection from the northwest and turns left (east) to continue toward Windham while traffic proceeding straight through the junction is directed on NY 23A. It heads generally southward along the eastern banks of Schoharie Creek, continuing the course set by its parent route through northwestern Greene County. Along the way, the route serves numerous state-maintained parking areas providing direct access to the creek, a popular trout stream among fly fishermen. At one of these stops, it begins to run southwestward along the Blue Line delimiting the boundaries of Catskill Park. After 1 mile (1.6 km), the creek and the route turn to the east, crossing into the park limits.
