We have booked for a trip to California for early May and are struggling on a route from Vegas to San Francisco. Reading elsewhere on this site it is likely that the Tioaga Pass and roads 108 and 4 are likely to be closed. We want to take in Death Valley, Yosemite NP and the Big Sur coast. Does anyone have any suggested scenic routes to see them all (and more!) in 6 days (we have a couple of spare days after this to see San Francisco)?
