We'd like to head north for a few days (to Portland, perhaps) then turn around and go south, see Tahoe, Yosemite, Mono Lake, Death Valley, Vegas, GC and LA. Then take Highway 1 back up to SF.
Is that doable in 12 days? Enjoyable? We're in Switzerland and it's almost snowing, so we definitely want to see some sun. Should we forget Portland and head south from the start?
Route suggestions appreciated!
