The County of Northumberland extends along the north side of Lake Ontario as far east as Trenton and the Bay of Quinte.  Most of the larger urban communities are situated between Highway 401 and Lake Ontario.  

The central portion of Northumberland is dominated by the Oak Ridges Moraine.  The provincially-owned Ganaraska Forest is an extensive area of native and plantation forest tracts that mark the eastern terminus of the Moraine.  South of the Moraine the dominant Greenlands features are the unprotected woodlands of the glacial Lake Iroquois shoreline.
