History
Mountain Lakes was originally a planned community, founded in 1910 by Herbert Hapgood. The entire face of the community changed from a wilderness of Dutch and English properties to a planned suburban community of large stucco houses now affectionately known as "Hapgoods." During this single decade, the natural and architectural character of Mountain Lakes was developed. Hapgood was particularly influenced by the Arts and Crafts movement, at the height of its popularity in 1910 when he started building. Lawrence W. Luellen, inventor of the Dixie Cup, became the community's first resident when he moved to his new home in March 1911. The Hapgood model homes were early forerunners of the modern development, but each house was modified to suit individual tastes. To the basic styles of these houses, Hapgood added colonial and craftsman features. He reversed floor plans, and interchanged architectural details. By the end of 1912, two hundred Hapgood homes were sold and occupied and in 1914 saw the formation of the Mountain Lakes Club. By 1923, approximately six hundred stucco houses were built to meet the overwhelming demand. Mountain Lakes became an independent municipality in 1924. The United States Navy's Underwater Sound Reference Laboratories was located in Mountain Lakes during World War II. Mountain Lakes had a discriminatory "gentleman's agreement" from its inception up through the 1960s, preventing African-Americans, Jews, Latinos, Catholics, and other "undesirable groupings" from living there. While this was abandoned in recent years, the town still has a less diverse population than the rest of New Jersey, or Morris County.

The borough borders Parsippany-Troy Hills, to the east and south, the town of Boonton to the northeast, Boonton Township to the northwest and Denville to the west all of which are located in Morris County. Man-made lakes in Mountain Lakes include Birchwood Lake, Crystal Lake, Mountain Lake, Shadow Lake, Sunset Lake, Wildwood Lake, and Cove Lake. There are town private swimming beaches in Birchwood Lake, and Mountain Lake. The Mountain Lakes Club is located on the northern end of Mountain Lake.

Beach badges are available to Mountain Lakes residents only.
