Took a ferry out to Angel Island State Park which was a nice way to enjoy my first day San Francisco,
Advice - but the ferry ticket (operated by Blue and Gold Ferries) in the Ferry Terminal. We looked around and couldn't find where to buy the tickets until we asked someone. Buy a sandwich or something to eat while on the island and when you get to the peak of Angel Island the view is very rewarding and you can sit and eat lunch there on one of a few tables around.
Walks are relatively easy.
