Hi everybody! Visiting SF and need some advice about where to go outside of SF! x-post from /r/bayarea

I'm visiting SF from Wednesday April 6th to the Sunday the 10th. Some of my best friends in the world live in SF but haven't really seen anything outside of it. So I'm renting a car from friday morning to sunday morning and I need advice on where to go! Both I and them have no idea where to go, but I was thinking somewhere out of the Bay but not more than a 5 hour drive away. I would love your advice! Tahoe? Yosemite? Napa? Monterey?
