Hi K....I've read all the posts so far and most are right on! The one thing I would emphasize is Muir Woods. It is a chance to see the giant redwoods right there close to SF instead of having to travel up to northern CA or elsewhere! It's awesome!! I took my 80 yr old mother for her 80th bday and she said it was the highlight of her life!!! Lots of trails to hike! One tip: there is a small parking lot which will most likely be full. If there are lots of cars parked on the road, (I once had to park about a mile away), keep circling the parking lot for awhile to see if you can snag a spot! Maybe you'll be lucky and get a spot right away!! TIP: It costs $5 to get back across the GGbridge! Or it did when I moved from CA.
Another must do eating spot is Scoma's on the wharf..it's kinda hidden, go hungry!!
You must do Alcatraz, but always buy your tickets early..contact your hotel!!! Rent the audio set, you get to hear the "inmates" talking, cell doors slamming, etc. Sometimes there will be a former inmate doing a book signing!
A good place in Chinatown to eat dim-sum is Yang Sing at 427 Battery. Be careful, the tab can rise quickly, cause everything is so good! Walk the main street in Chinatown, I think it's Stockton. You'll feel like you are in another country!
Monterey & Carmel are neat but it's about 1 1/2 hours drive, so it's not like it's down the street! Carmel has awesome beaches. I always take a blanket, some wine and cheese and sit and watch the sunset!! But again, it will be cool or even cold in the summer! Take jackets or sweatshirts & be able to layer. If you do 17-mile drive thro Pebble Beach, it cost around $7 to drive thro, but if you eat at one of the restaurants, take your receipt and they will refund it. You can eat right on the 18th green of the golf course!
I wish you had time to go to Yosemite!!! It is the most awesome place in the world! Plan another trip in early June and the waterfalls will be exploding!!
There are so many things to do! SF is a great walking city. Don't know where you are staying, but we once walked all the way from Union Sq to Ghirardelli Sq. Then caught the cable car back up. Take comfortable walking shoes!! Another neat thing to do is hike or drive up to Coit Tower, and OH you must drive up to Twin Peaks (if it's not foggy!) AWESOME views!!
Hope this helps!!! D. G. Oh ps,,,I've never been to the jelly belly factory, but it's in Fairfield, not right in SF...I personally would not take the time to do that, I'd rather go south to the Monterey area and do the beaches and aquarium!! Just fyi
