Analysing terrain data
The exposure grade describes the potential consequences of falling or slipping off the path.
Low Exposure: The path is on completely flat land and potential injury is limited to falling over.
Medium Exposure: The trail contains some obstacles such as outcroppings and rock which could cause injury.
High Exposure: Some trail sections have exposed ledges or steep ascents/descents where falling could cause serious injury.
Extreme Exposure: Some trail sections are extremely exposed where falling will almost certainly result in serious injury or death.
The southern terminus for this segment is VA-56, often referred to as Crabtree Falls Highway.
Due to its location less than an hour from Charlottesville, plus its proximity to other major highways and the Blue Ridge Parkway, the latter half of this segment is extremely popular for day hiking. To begin this segment, cross the bridge over Tye River and begin the climb with a series of switchbacks.
Once you reach the intersection with the Mau-Har Trail, keep right on the Appalachian Trail.
After a short descent, you'll continue climbing to Chimney Rock and the summit of Three Ridges. A few quiet and solemn overlooks line the way as you finish out the 3,000-foot climb between Tye River and the summit of Three Ridges.
After descending from the summit, you'll reach the Maupin Field Shelter at the northern junction of the Mau-Har Trail—a route often used to create a loop.
In addition to the shelter, the surrounding wilderness area provides plenty of overnight camping opportunities. Crossing the small parking area along Beech Grove Road, the trail follows the Blue Ridge Parkway Corridor until the Wintergreen Resort.
In this area, you'll cross over the unique and picturesque rock formations of Cedar Cliffs and Dripping Rock, both easily accessible from the road.
Know that camping in this area is limited in order to prevent erosion or other damage. Soon to follow, a spur trail leads towards the Humpback Rocks Picnic Area.
If day hiking, this area serves as an excellent staging area or place to have lunch afterward. Ahead on the trail, you'll cross over Humpback Mountain and the iconic Humpback Rock, a pinnacle emerging from an enormous granite formation below.
A quick spur trail leads to the overlook, and can become quite popular in the spring and fall.
Atop, you'll be welcomed with epic views to the west. Finishing the segment, continue north through countless switchbacks as the trail makes its way to Rockfish Gap at Interstate 64. Sources: https://en.wikipedia.org/wiki/Humpback_Rock
