I'll start my road trip in San Diego the week of the 13th of August. Stay few days there and then drive to :

-Los Angeles

-Las Vegas

-Sequoia Park

-Santa Barbara then driving on the coast road to Big Sur

-Yosemite (if it's open)

-Maybe other parks around Yosemite

-Finishing at San Francisco around the 28th of August

Obviously, I'm open to any changes I just want to see in two weeks as many things as possible in California. It's also fine if you just want to join for a few days.
