My husband and I are planning a trip out to California in mid March. We are flying into Las Vegas and from there are thinking of heading to Death Valley, then Sequoia NP. From there we're thinking of heading to Yosemite, and then to Napa to explore wine country. Our next stop after the wine, would be San Francisco, then we'd like to head down the coast and back over to LV for our flight home. Any advice would be greatly appreciated. We have about 10 days.
