Stillwater Township occupies a broad rural area in western Sussex County. Lakes, farms, wooded hills, historic villages, streams, and low-density neighborhoods define its landscape. Routes 521 and 94, together with local roads, connect Stillwater with Newton, Fredon, Blairstown, the Delaware Water Gap region, and communities throughout northwestern New Jersey. 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 community’s location and surrounding landscape continue to influence its development and everyday character. Residential areas, civic uses, business activity, open space, and local roads together define the township’s physical and community layout.
