The presidio was an army post for over 200 years. Today many tourists visit the military buildings to explore the architecture, national cometary, airfield, forests, or neighboring beaches. Just a quick walk from the Golden Gate Bridge it is a great addition to any day out in San Francisco.
Not really a 'hike' per se but should be on your list if you live in or near the Bay Area. I've gotten lucky sometimes and had fewer tourists on the bridge but also been so crowded I could barely manoeuvre through the selfie-taking hoard.
But press on: the crowd thins before the halfway point and it's an absolute dream walk looking out at the Pacific and back at the Bay.
FIVE stars for the history and views from the bridge. I was born nearby at Letterman Army hospital. I did this along with Angel Island one day a few years back with a friend and it was one of my favorite days in life. I also love to be at the helm of my boat on the way out under the Golden Gate Bridge. EPIC
