Life on Lake Hopatcong
Mount Arlington occupies part of Lake Hopatcong's eastern shoreline. The lake has shaped the borough's recreation, history, residential development and identity for more than a century.
The municipal beach serves borough residents with seasonal lifeguards and beach grounds that include volleyball, bocce and horseshoe facilities.
Marinas, private docks, lakefront homes and longstanding boating organizations continue the recreation culture that helped establish Mount Arlington as a resort community.
Lake access comes with shared stewardship.
Lake Hopatcong crosses municipal and county boundaries. Water quality, boating rules, harmful algal blooms, aquatic weeds and public access are regional issues, and the borough continues to participate in Lake Hopatcong Commission initiatives.
From resort destination to year-round borough
Mount Arlington's history is inseparable from the rise of Lake Hopatcong as a major recreation destination for residents of New York City, Newark and North Jersey.
Large hotels, summer cottages, excursion boats and private clubs turned the Lake Hopatcong shoreline into a fashionable warm-weather destination.
The borough was incorporated from portions of Roxbury Township during the lake's resort boom.
Visitors arrived by rail and continued across the lake by steamboat or launch to hotels, clubs and vacation communities.
The nearby amusement park became one of Lake Hopatcong's best-known attractions and remained part of the region's summer culture until 1983.
Large-scale resort development helped establish Mount Arlington as an upscale lake destination and encouraged the building of summer cottages around the shoreline.
Founded during the lake's resort era, the club remains one of the most recognizable surviving institutions connected with Mount Arlington's boating history.
As automobile travel and suburban development changed vacation patterns, Mount Arlington evolved from a seasonal resort into the primarily year-round residential borough seen today.
