About Mount Arlington

Perched along the southeastern shore of Lake Hopatcong in Morris County, Mount Arlington offers a relaxed lakeside lifestyle with a friendly, small-town atmosphere. Once a popular Victorian resort destination known for breezy summer getaways, the community has grown into a quiet residential borough of around 6,000 people. Housing options range from vintage lake cottages and newer single-family homes to low-maintenance waterfront townhomes, giving new residents plenty of ways to enjoy the scenic setting.

Life here naturally centers around the water, with weekends often spent boating, fishing, or dining by the docks. Even with its vacation-like setting, Mount Arlington is surprisingly convenient for everyday routines. Commuters benefit from direct access to Interstate 80 as well as a local NJ Transit train station with service across northern New Jersey and into Manhattan. Local kids attend town schools from kindergarten through eighth grade before moving on to nearby Roxbury High School, creating an easy balance between outdoor recreation and suburban convenience.
