Best scenic route from SFO international Airport to Pacific Grove to Death Valley onto Las Vegas.
Your answer from PG to Death Valley was answered in your other post by Kibblesmom. There is a difference between the best route and scenic route. Most of the central valley drive is not that scenic.
To get to Pacific Grove, once you pick up your rental car, you should head to 380 W to 280N and take the exit to Hwy 1 to Pacifica and go on Hwy 1 all the way to Pacific Grove exit .
