Upon crossing into Wantage Township, the road makes a turn to the east and passes a mix of homes and businesses as well as the Space Farms Zoo and Museum. CR 519 heads northeast into more farmland as it comes to a turn north onto Colesville-Lusscroft Road. The route runs through more rural areas with some residential development, eventually making a bend to the northeast. CR 519 continues to an intersection with Route 23, where it turns north for a concurrency with that route. The two routes pass through forested areas with some homes until CR 519 splits from Route 23 by heading north on Greenville Road. This road carries the route north, entering dense forests and crossing the Appalachian Trail before it comes to the New York border. At the state line, CR 519 ends and the road continues into Orange County, New York as CR 55.
