pier 39 Is my favorite, there's an aquarium of the bay, the best clam chowder and lots of sea lions gather at the end of the pier! but also Haight Street street is cool downtown, trolleys, tours, plays, China Town all the SF City life!
There are many red wood hikes to the beach as well in this area!
Kristies favorite beach!
Yosemite is beautiful but 2 hours away!
