Blackrock Trail is located on a south-facing slope, which promotes the dry, thin soils along the pedlar gneiss rock formations. Mountain laurel, blueberry, and rose azalea thrive in this harsh environment and are in bloom during June.
Brimstone trail is steep with rocky cliffs which provide incredible views of Three Ridges Mountain and points to the southwest. The trail meanders below the Plunge and consists of a series of steep, short up and down sections.
This trail is very rocky and steep in portions.
