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. The dominant tree species found along the trail are chestnut oak and table mountain pine; note the way the southwest winds shape these pines. It connect to the Pedlars Edge Trail. Use caution in winter.
