The James River is a river in the U.S. state of Virginia that begins in the Appalachian Mountains and flows 348 miles (560 km) to Chesapeake Bay. The river length extends to 444 miles (715 km) if one includes the Jackson River, the longer of its two source tributaries. It is the longest river in Virginia and the 12th longest river in the United States that remains entirely within a single state. Jamestown and Williamsburg, Virginia’s first colonial capitals, and Richmond, Virginia's current capital, lie on the James River. Source: Wikipedia
