An official Path Through History Site! The Congressman Maurice D. Hinchey Catskills Visitor Center seeks to educate and inform visitors about the history, culture, natural resources, recreational opportunities, and geography of the Catskill Park and the Catskill Region. The Catskills were formed 300 million years ago and were carved by the glaciers of the last ice age 25,000 years ago. Humans have been occupying the Catskill Region for the past 10,000 years. More recently, the Catskills were settled by tribes of the Lenni Lenape people, then the Dutch followed by the English and a number of other European groups including the French and people of German heritage.
