Vernon Township occupies the northeastern corner of Sussex County along the New York State border. The municipality covers a large area of mountains, valleys, forests, farms, and lake communities within the New Jersey Highlands. Route 94 and Route 515 provide the principal local connections, linking communities such as McAfee, Vernon Center, Highland Lakes, Glenwood, and Vernon Valley. Mountain Creek and nearby recreation destinations make the township a year-round center for skiing, golf, hiking, and outdoor events. Sections of the Appalachian Trail cross the area, and Wawayanda State Park extends along the township’s northern landscape. Residential development ranges from lake associations and compact neighborhoods to rural homes and larger wooded properties. Vernon also contains schools, municipal facilities, small business corridors, and preserved open land. It borders Hardyston, Hamburg, Wantage, West Milford, and several New York communities, giving the township strong geographic ties to both northwestern New Jersey and the lower Hudson Valley.
