I first hiked to Camp Rapidan in late June and have been back several times. In the late 1920's - early 1930's President Hoover frequently vacationed there and invited world leaders to join him. It's a gentle 1.8 mile hike from the Milam Gap area and really worth the side trip. There are 6-8 of the original buildings still there and the foundation of others. A NPS volunteer just arrived at the camp and opens up the buildings every day. On Sunday afternoons there a shuttle from Byrd Visitors Center to the camp at 1400. Reservations required. Caution - lots of large snakes around the remaining structures and mowed areas. They're mostly large water snakes, though rattle snakes and copperheads have been reported this year.
