This is a 17.3-mile, point-to-point backcountry itinerary, not a loop. It starts at South River Picnic Area, follows the Appalachian Trail to Lewis Mountain, crosses Laurel Prong through Rapidan Camp, then uses Mill Prong Horse Trail, Mill Prong, more Appalachian Trail, and Lewis Falls Trail to reach Big Meadows Picnic Area. Plan for three days and roughly 15 hours on trail across the three days, including ordinary stops; add camp setup, meals, and the two nights. The written itinerary is old, so confirm the exact route and access before setting out.
