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.
Keeping its rhythm of flattop ridge traverses, the AT crosses I-81 as it traverses a peaceful—yet rocky—stretch though State Game Land 80.
This stretch through "Rocksylvania" will push your focus to the limit as you traverse through fields of boulders. Heading northeast, the trail crosses through fields of talus rock formations as it traverses over the ridge.
Overlooks and vantage points line this portion of the trail and should always be enjoyed. Continuing north on the AT, you'll pass a shelter, then PA-645, a popular access point for the trail.
As the trail approaches PA-501, it winds onto a talus slope, giving an excellent vista to the south.
Adjacent to the road is the 501 Shelter, another opportunity to spend the night. The next portion of the trail is an excellent opportunity for a day hike as the trail alternates between dense, lush forests, and exposed slopes with killer views.
The trail turns briefly southwest and traverses a point known as Round Head.
A shorter, but steep, approach via the 500 Steps Trail is another way to reach the excellent viewpoint. Crossing PA-183, a large parking area lies adjacent to the trail and serves as another way to access the trail.
Continuing north, the trail re-enters a monotonous stretch through more State Game Lands and past Eagles Nest Shelter.
A nearby overlook makes this an excellent opportunity to spend the night before rounding out the final piece of this segment.
Paralleling a dirt access road, continue north to the Schuylkill River.
The AT intersects the Schuylkill River Trail before crossing through Port Clinton to a trailhead on the opposing side of the river.
