Grand Canyon is one of the most well-known natural wonders of America. This steep-sided canyon was carved by the Colorado River in Arizona. The unique combinations of geologic color and erosional forms decorate this canyon that is 277 river miles long, up to 18 miles wide, and a mile deep. Its immense size and intense beauty overwhelm the senses of each and every visitor. The easiest trail is the flat, paved Rim Trail and the classic 9.3-mile Bright Angel Trail is more strenuous but certainly worth it. For those who don’t want to go on foot, there is another option, exploring the site on a mule. Just one look at this place gives the visitors a new perspective and a thrive to go and explore the trail as long as they can. Thrill seekers can raft the Colorado River, or take a helicopter ride over the Canyon. Havasu Falls is a hidden oasis for hikers willing to trek out to the remote waterfall. No matter which activity the visitors choose, this national park will certainly leave them a beautiful memory.
