Natural wonders of america

Grand Canyon National Park

Measuring a mile deep, up to 18 miles wide and more than 275 miles long, no other sight in the USA beats this giant hole in the ground for instilling stupefying awe. Peering over the edge of the Grand Canyon is enough of a thrill for some, but to really appreciate the canyon’s grandeur, hike all the way down inside it to the rushing Colorado River.

Top tip: To escape the crowds, visit the canyon’s North Rim, which gets one tenth as many visitors as the South Rim. Note that the North Rim is now closed for the 2020 season.
