San Francisco鈥?one week鈥 think it is definitely enough to make the most out of this fabulous city. Why do I say so? Because I visited SF last month with my sister for 5 days, quite worthwhile lol

The most notable attractions in San Francisco are no other things but:

Golden Gate Bridge: an iconic construction recognized both nationally and internationally. Bet you must have seen it in many movies and photographs taken place in SF. It is an engineering wonder, as well as a landmark for the city and for California itself!

San Francisco Zoo: whether you are interested in wildlife and nature or not, this zoo is a must visit on your itinerary! There houses over 260 species and contains an inviting children鈥檚 zoo, miniature train and carousel. This is a good place to chill out or have fun with families or friends.

San Francisco Bay: how can you skip the breathtaking Californian beaches and sun? if you visit SF in the right time, be sure to go to the bay area for waterfowl and whale watching!! Lots of people flock to the bay for whale watching each year. It will never disappoint you!

Chinatown: SF has the largest Chinatown throughout the world, also the oldest in its kind in Northern America! So there seems to be no reason to miss out it. Here you have opportunity to taste the authentic Chinese cuisine and find affordable yet distinctive Chinese traditional crafts and woks.

The Exploratorium: explore science and secure an up-close look at the latest technology right here! It is the one-stop destination to experience the magic and marvel of modern science at its finest.

Of course top attractions in SF are far more than I listed above. I suggest you to check this website carefully. We used it for our trip. It includes travel recommendations %26amp; tips, activities, transportation, dining, etc鈥︹€retty helpful and informative.

As SF Caltrain, it is a bit difficult to tell you the specific fare. It depends on the number of the zones that you actually travel. For instance, travel within one zone, one way, the fare is $2.75, while within 3 zones, the rate is $6.75.
