I'm trying to plan a 14 day road trip from vegas to redwood national park at the end of july. Flying in to Las vegas but driving out to death valley same day. I would like to stop at death valley national park and then go white water ratfting in kernville,then head up to Sequoia and king national park, yosemite n.p., san francisco, napa valley, larssen volc. n.p., and lastly redwood national park. I'm i spreading myself to thin? Is 14 days enough and what part will be the longest driving period. i would greatly appreciate anyones comments and advice!
