Its landscape includes lakes, farms, wooded neighborhoods, historic roads, and portions of the county’s rail-trail and recreation network. Routes 206 and 517 provide access to Newton, Sparta, Byram, and Interstate 80, while local roads connect the township’s smaller communities. Sussex County occupies the northwestern corner of New Jersey and is defined by the Kittatinny Mountains, Highlands, lakes, farms, forests, and small boroughs. Its communities are generally lower in density than those farther east, while Routes 23, 94, and 206 provide access to regional centers and neighboring states. The result is a community that retains its own identity while benefiting from the transportation, employment, and cultural resources of the larger county.
