The Rappahannock River is a major river in Virginia, flowing approximately 195 miles from the Blue Ridge Mountains to the Chesapeake Bay. It is known for its scenic beauty and historical significance, particularly during the American Civil War, when it served as a strategic boundary between Union and Confederate forces. The river's watershed supports diverse ecosystems and provides recreational opportunities such as fishing, kayaking, and hiking. The city of Fredericksburg, located along the river, is famous for its Civil War battlefields and historic sites, making the Rappahannock an important cultural and natural resource in the region.
