Yes, I've been to San Francisco (inside the city limits and outer) countless of times. I can't remember how many times I've been there, LOL.
I grew up going to the Bay Area because my grandparents used to live there and I'd visit/stay with them during the summer time. I also have some extended family members that are still living there, so whenever I go to California, I get to stay with them.
Anyway (oops, my bad for getting a bit off topic) - Fisherman's Wharf is one of the most top tourist spot in SF along where Ghirardelli Square is at.
Golden Gate Park is also a nice place to go to for a picnic or a jog or whatever. If you haven't seen Golden Gate Bridge at night time, You should because I think it's one of the most beautiful spot on the earth. Well, You could say that I'm a bit biased because I just love going there.
Also, take a tour at the Alcatraz - a lot of interesting thing to see at Alcatraz.
The aquarium of Bay is another spot to check out. It's really nice to see all these marine life. I found it enjoyable to go to.
Presido - It was once a military post and is now a natural park. It's got hiking trails, so and on. If you enjoy nature, this is the place to check out.
And of course, It's summer time - It's time to hit the beach and where better to hit it at? San Francisco Beach!
