Herkimer County

Created in 1791 and named for Revolutionary War figure Nicholas Herkimer, the county stretches from Mohawk Valley communities into Adirondack landscapes. The river, canal corridor, villages, and old industrial centers tell a story of movement and reinvention. Little Falls, Herkimer, Ilion, and other communities remain closely tied to that transportation heritage, while the northern part of the county opens into lakes, forests, and mountain recreation.

A day can move from canal-side history to a hike, lake, or family attraction without leaving the county. Visitors can dig for quartz crystals, explore historic sites, follow the Erie Canalway, or head north toward Old Forge and Adirondack recreation. Residents have access to regional education, health care, small-town services, and a network of communities that connect the Mohawk Valley with the North Country.
