Be Smart
No matter how overheated you are after hiking through the Grand Canyon, NEVER jump into the Colorado River. The water is freezing and deep, the current is powerful, and many swimmers have drowned there. Just make sure you have a bottle of water with you to quench your thirst.

National parks aren’t just tourist attractions. Scientists frequently conduct wildlife research away from visitors’ eyes. You might get a glimpse of them not in full uniform, just gathering data, said one park ranger.
The ranger went on to say that one of her favorite parts of working at the parks was the chance to spend a day observing them and watching what they do.
