Fort Miley to Lands End

"Fog horns under Golden Gate Bridge"

Atop Fort Miley, you hear the symphony of ships fog horns as they pass under the Golden Gate Bridge.  Hike the top trails, and you get a good view of the Bridge from the top. You can walk down the stairs to a wide hiking trail with a view of the ocean, wild flowers and tall pines.
