Q: I need to know how to go to river san joaquin from san francisco... please answer
A: The San Joaquin River isn't in Sacramento, so I'm not sure which you want ~ the San Joaquin River OR the river(s) in Sacramento. If it's the rivers in Sacramento, that would be the Sacramento River and the American River ~ their confluence is in Sacramento, CA. I agree with the previous poster ~ from San Francisco take I-80 east. If it's the San Joaquin River you were wanting, that empties into the San Joaquin Delta at Stockton, CA. To get to Stockton you would take I-580 to I-205 to I-5. Hope this helps!
