1. Lands End
This is probably the most well-known hike in San Francisco, beginning at the Lands End lookout near Ocean Beach, part of the Golden Gate National Recreation Area. Check out the dramatic ruins of the Sutro Baths while you're there. Then, head east along the beautiful coastline and rocky cliffs overlooking the water. You'll walk through shady and fragrant cypress and eucalyptus trees and end with a gorgeous view of the Golden Gate Bridge. History buffs will want to pause at the USS San Francisco memorial erected to honor the WWII ship.
