The colorful rock formations of Red Rock Canyon National Conservation Area, located just 17 miles west of the Las Vegas Strip, Jan. 3, 2017. This unique desert land, encompassing nearly 200,000 acres and offering biking, hiking and spectacular photographic opportunities, is an easy side trip for millions of tourists each year.

First, the fine print: Not everyone will be able to find deals at the prices I’m going to show you, partly because airlines can (and do) change prices really fast thanks to supply and demand. But you can cut costs down for many flights by flying out of a big hub airport -- New York, Chicago, Los Angeles -- because the mega-cities typically have the cheapest airline tickets. Finally, don’t choose a vacation destination simply because it’s cheap, but I think it should be a factor. We have a wide variety here and with luck, one is on your bucket list.
