Depends on the time of year. If the weather is good and you have a car I would definitely go to the Grand Canyon, Valley of Fire, Red Rock Canyon, Hoover Dam, Zion National Park, Bryce Canyon, Oatman, Arizona and Death Valley. People think of Vegas as a destination, but it is a stepping off point for many Natural Wonders close by. You also have a number of racing options down by the Speedway which include Dune Buggy riding, racing a Lambergini or Ferrari, etc. If you are into weaponry, there are numerous options for firing semi-automatic and machine guns. You can book an evening cruise on Lake Mead or helicopter over (or into) the Grand Canyon. There are daily hot air balloon rides that lift off around dawn.
