Cadyville, NY

Cadyville is a Clinton County hamlet and census-designated place along the Saranac River and New York State Route 374, where the 2020 census counted 479 residents. The community sits about 8.8 miles west of Plattsburgh at roughly 745 feet above sea level. A post office opened here on July 25, 1840, and students attend Saranac Central School District.

The Saranac gives Cadyville its strongest geographic line, while Route 374 carries the hamlet into the wider North Country road network. Plattsburgh supplies the larger-city connection, but Cadyville keeps a separate address, post office, and school relationship. The river corridor also places it in a landscape shaped by Adirondack foothills, farms, and the routes that run toward Lake Champlain. The post office and school district give the river crossing a civic life beyond the highway, tying older settlement patterns to present-day routines. Cadyville is a small New York place whose everyday map is easy to picture: water beside the road, a long-established post office, and a short drive west of Plattsburgh.
