This is a terrific and easy day trip just 15 minutes from the Strip. You will be astonished at how easy it is to forget about all that money you lost in Las Vegas and enjoy the quiet drive through the Red Rock conservation area. There are a lot of scenic stops and you may even spy a wild donkey or two :D
Remember to bring your camera (or your smart phone - but be warned both Verizon & AT&T get limited service out here so your tweets and geo location check-ins will have to wait until you come down from the mountain). Skip the "Springs" and spend some time at Callico #1 which is a super easy-for-everyone 10 minute rock climbing adventure. You'll also get some amazing photos for your scrapbooks.
The best part is that while it's extremely gorgeous and quiet here, it's not far from civilization. Red Rock Canyon Casino is just up the road a piece as is dining and entertainment - so after spending a nice couple of hours here, it's easy to get right back on the road to Vice
