There are many ways to see the Grand Canyon, including from an overlook in your car or RV to the Skywalk, an extended porch built (in 2007) and maintained by the Hualapai Nation, a native people to this region. Skywalk is NOT a part of the Grand Canyon National Park, but nevertheless provides a stunning view of the area. If you are a true nature buff, the best way to see the Grand Canyon is via a hike.

More than five million people visit the Grand Canyon annually, which presents a difficult challenge for the park service to maintain a pristine sight. In fact, the National Park Service recently banned the sale of bottled water at the Grand Canyon, so as to prevent the site from being littered by millions of plastic water bottles. The NPS has set up a page of information for how to travel "greener" at the Grand Canyon.
