Seneca Shadows Campground overlooks Seneca Rocks and is surrounded by mountains on both the east and west. Hiking and nature study at Seneca Rocks are just a couple of the popular activities in the area. The North Fork South Branch Potomac River is nearby, making fishing a popular pastime. Two local caves beckon ambitious explorers, and the 900-foot high Seneca Rocks can be viewed from most campsites.
