The region's large shopping malls, such as Potomac Mills and Tysons Corner Center, attract many visitors, as do the region's Civil War battlefields, which include the sites of both the First and Second Battle of Bull Run in Manassas and the Battle of Fredericksburg in Fredericksburg. Old Town Alexandria is known for its historic churches, townhouses, restaurants, gift shops, artist studios, and cruise boats. The waterfront and outdoor recreational amenities such as biking and running trails (the Washington and Old Dominion Rail Trail leads all the way from Alexandria to the foothills of the Blue Ridge; the Mount Vernon Trail and trails along various stream beds are also popular), whitewater and sea kayaking, and rock climbing areas are focused along the Potomac River, but are also found at other locations in the Baltimore–Washington metropolitan area. Scenic Great Falls Park and historic Mount Vernon (which opened a new visitor center in 2006) are especially noteworthy. The Government Island park and quarry in Stafford County has views of the Potomac River, and Aquia Creek and also is where the building materials for the White House, and United States Capitol are from. Also in Stafford County are historic places such as George Washington's boyhood home Ferry Farm, Civil War headquarters and plantation Chatham Manor, and artist Gari Melchers Home &amp; Studio.
