CITY'S BEAUTIFUL BUT HIDDEN SAND DUNES

...Unfortunately, they're beneath 300 feet of water outside the Golden Gate.


San Francisco long has been renowned for its hills, bay and bridges -- but not for expanses of sand dunes. That's liable to change.
It turns out there are more than 2 square miles of dunes right next to the city, and world-class dunes at that: Only a few sites around the globe have larger dunes of this sort.
Access, however, will remain difficult unless you're a sand dab or Dungeness crab. The dunes are just west of the Golden Gate, submerged in 100 to 350 feet of sea water.
