Wantage Township is a large rural municipality in northern Sussex County surrounding Sussex Borough and extending toward the New York State border. Its landscape includes farms, wooded ridges, streams, wetlands, open fields, and widely separated residential communities. Route 23 is the main regional highway, while county roads connect the township with Hamburg, Branchville, Frankford, Montague, and Vernon. Named communities such as Quarryville and several historic crossroads contribute to Wantage's local geography. Schools, municipal facilities, small businesses, agricultural properties, and residential neighborhoods are distributed across the township rather than concentrated in a single downtown. The Wallkill River valley and the nearby Highlands shape the terrain and support both farming and recreation. Wantage retains a strong rural identity despite residential growth, with substantial open land and scenic roads. Its northern location and relationship with Sussex Borough make it an important service and transportation area for the upper part of Sussex County.
