We started the day at the Ferry Building which is a great place to grab some lunch from the Farmer's Market to picnic with on the Island. The Blue and Gold line to Angel Island picks up behind the Ferry Building (but will only drop you back off in Fisherman's Wharf) and you can buy your tickets either in the building or even on the boat itself.
It was a good time of year for flowers at the Farmer's Market:
The views as the ferry leaves SF are really great. I tried to make these first few look like old postcards, I think it worked!:
America's Cup Prada boat & Alcatraz:
Some panoramas happened:
On the island itself, there are lots of interesting buildings from back in the day when it was a fort and immigration station:
