At this junction, the path divides into three options. If you're arriving from the South Headlands Trail, you can take the South Trail in two directions. If you want to go to the Fern Canyon Trail, simply turn right at this junction. If you prefer to head to the campground, go left.
Alternatively, if you're coming from the campground, turning right will lead you to the South Headlands Trail, while continuing straight will keep you on the path to Fern Canyon Trail.
