Though I have this listed in my Vegas Vacation you should know that this state park is in California and is an all day car trip. I used a tour recommended on Vegas.com site. I drove first to Dante's Peak to look down on Death Valley. Next a stop a Zabriske point. A stop for lunch near the floor of Death valley. Then it was on the alkaline flats of Death Valley some 260 feet below sea level. While there we did a very long drive to Scotty's Castle but the mansion/castle was near closed by the time of the day we arrived.
