San Francisco to Yosemite - where should I stop along the way?

I'm driving from SF to Yosemite. Wondering where I can stop along the way for other fun/touristy things to do... even restaurants, whatever.



it's a 4+hour drive. I need breaks.



For my wife and I, both in late 20's.San Francisco to Yosemite - where should I stop along the way?
On Hwy 120, you should stop at rainbow pools. It's right off the road past buck meadows. Stop there and get directions. It's about 2 miles past there and is only a couple of hundred yards off the Hwy on a paved road. Bring your swim suit and be prepared to have a blast. Iron Door Saloon in Groveland is OK too.
