The trail has a few steep climbs that give challenge to trail hikers and also has commanding views of the golf course, eucalyptus trees and chapparral. 

Black Sage Trail - This trail gets it's name from the native sage plant found in much of the coastal sage scrub that is along the trail and growing in the canyons adjacent to it.
