About

Mountain Lakes is located in north-central New Jersey where the rolling hills of the New Jersey's Piedmont region meet the rocky outcroppings of the Highlands.

Our History

In 1910, Mountain Lakes was a rural woodland owned by a few families with names such as Righter, Grimes, Ball and Van Duyne. In the space of ten years, however, the entire face of Mountain Lakes changed from a wilderness of Dutch and English properties to a planned suburban community. Learn More
