    Did You Know That There Are Abandoned Military Bunkers In San Francisco?

    There are! Attention Urban Explorers; across the Golden Gate Bridge in Marin County there is a little place called Point Bonitas, where the civil war era bunkers still stand. It is quite an eerie sight against the bay area cityscape.

    2. Hiding in the hillside

    3. They are all overgrown, but still accessible if you know where to look.

    4. Unfortunately, it has also become a Graffiti artist's playground.

    5. Inside is rather spooky

    6. Enter if you dare! Guess what? We did.

    7. Spook Hole?

    8. These pipes don't lead anywhere...

    9. They are completely buried underground

    10. Vandels found their own way in....

    11. This is where they would lift the cannons up.

    12. It just kept going and going

    13. Tunnels also went on forever.

    14. I think this might actually be a spaceship....

    15. This one was made out of wood
