Welcome (in advance)!
Union Square is great. While you're at Fisherman's Wharf don't forget to get all the way down to Ghirardelli Square.
Other things in SF:
- California Academy of Science (
San Francisco Aquarium, Planetarium and Natural History Museum | California Academy of Sciences) an excellent museum which is right in front of the Japanese Tea Gardens in Golden Gate Park. You can easily spend a day doing both (hope the weather cooperates). If you still have some time, the DeYoung museum (
de Young Museum | de Young Museum) is very nearby.
- San Francisco Museum of Modern Art (
San Francisco Museum of Modern Art (SFMOMA)) and Yerba Buena Center for the Arts (Yerba Buena Gardens District -
Neighborhood | Yerba Buena Center for the Arts) they are in front of each other, in walking distance from Union Square.
- Exploratorium (
Exploratorium: the museum of science, art and human perception) and Palace of Fine Arts (
Welcome).
Do you guys want to explore further by any chance? If so, check out a day bus tour to Napa - there are several and most hit about 3-5 wineries in one day. Over the GG bridge is Marin county; Sausalito and Tiburon are beautiful towns worth exploring; there's also Muir Woods park (beautiful redwoods). On the east bay there is Telegraph Ave and Cal Berkeley (always a sight), there's also Tilden Park and Redwood Regional (if hiking is your thing).
There are also, of course, TONS of absolutely amazing restaurants everywhere, so if you guys are foodies, let me know what you like and I can suggest some spots.
You will have a great time!
