After parking at the lower lot of the Griffith Park Merry-Go-Round, run up the asphalt road until you reach the third dirt turn off. You'll run on the Old Zoo Trail
very briefly to reach the Fern Canyon Trail
, which you'll follow to the south (left). Once on the Fern Canyon Trail
the dirt path will take you up the hillside among the brush. While climbing you'll have great views of the San Gabriel Mountains on a clear day.
After running gradually uphill for a little over 1 mile you'll reach the 5-points intersection, which sits atop the ridgeline. The Fern Canyon Trail
comes to an end here and you can link up other trails from the juncture to extend your run.
