This is not just a place to park an RV for a weekend; it is a long-established, family-friendly seasonal community that operates from the beginning of May until early October, allowing residents to fully immerse themselves in the Northern New York lakeside lifestyle.

Hidden Harbor has cultivated a unique and much-loved environment, repeatedly described by its residents as a place where "friends feel like family."
