Driving Las Vegas to San Fransico via Death Valley

[Southwest Dave]

Hello Charlie.
As said by Michael and Buck , the only other option given your time scale and route is if the Tioga pass [120] is open. This would be my preferred choice as Buck explained it, leaving Vegas on the 160 to Pahrump and get on the 190 at Death valley junction. You just need to keep an eye on the conditions as per the link given.
To see Death valley and Yosemite be prepared for 2 long days, but very enjoyable ones.
