A curious mixture of trees and undergrowth lines the trail: where the path rises, the ground is a bit firmer and drier, with oaks predominating. But in the hollows, the going is slower, the earth damp and yielding, and alder and willow saplings thrive. To the south and west, the land is lower still.
