You can see the island of Alameda on the lower right, separated from Oakland by a narrow estuary. The Bay Bridge runs from Oakland to SF, and you can see the Golden Gate Bridge, a thin line on the left at the mouth of the bay. The Richmond bridge is to the north.
Ferries run daily to the island from San Francisco, carrying both tourists and commuters on their way to Tiburon and Sausalito. Many people bring bikes to the island or rent them (or Segways!) there. There's a nice road that runs all the way around, about five miles' worth. If I were a jogger living in SF, I'd probably go there once in a while for a pleasant change of scenery.
We considered asking for spare change when the open-sided tour buses passed us on the road.
The campsite was about two miles from the ferry, mostly uphill. Easy for me, coming from high altitude! The oxygen-rich air meant I wasn't even winded on the climbs. The kids had a meltdown or two on the way but made it without completely falling apart.
From the campsite we had a great view of the Richmond bridge and all the bay traffic. This photo was an accident, but it makes me laugh. ("Honey, I was taking a picture!" "Oops, sorry!")
I didn't take a huge amount of photos (need a bigger memory card!) but a few nice pictures of the trees and scenery are nice souvenirs.
Here's San Francisco and Alcatraz, marred somewhat by a dirty lens, alas.
And some trees:
Despite our proximity to civilization, the only night sounds were foghorns and ship horns and some wind. Oh, and some raccoons that came snuffling around after dark.
If you have a chance, you should try camping there yourself. It's not expensive; you'll just need to plan ahead if you want to go on the weekend, since the sites get booked up fast. Try it!
