Hamilton County remained a wilderness long after New York State had divided into counties. It was formed from Montgomery County on April 12, 1816 as a provisional county. Around 1840 it became an independent organization with the county seat at Sageville, the present Lake Pleasant.

It is located in the north-central portion of the state and contains approximately 1,806 square miles of beautiful mountainous terrain with many lakes, rivers and streams. It is New York State's third largest county, the least populated and located entirely within the Adirondack Park.

The county has nine towns and one incorporated village. Speculator, incorporated in 1925, is situated within the Town of Lake Pleasant.

Tourism is the most important industry and the whole area is a favorite spot for vacationers and sportsmen.
