Thornton River Overnight Loop is a 15.4 mile loop trail located near Sperryville, VA and is good for all skill levels. The trail is primarily used for hiking and is accessible year-round.
Just did 5 mi since my hiking partner had any breakfast .....
The parking area is small to non existent. So get there early.
Trail starts out pretty easy. Follows the river on a pretty flat and even path. There are a few water crossings which are easy. About a mile or so you'll reach the trail marker for Hull School, Piney Branch and Thorton. We tried both Hull and Thorton but each crossed the river, which was running pretty high. Since the temp was around 20 25 we decided not to attempt crossing. Backtracked to the Piney Branch trail which begins as as a steady a steady and moderate incline for about 1.3 mi. We hit another trail marker for Skyline, Jeremy's and other trails. We decided to return from here.
