Summer is the time of travel, and Grand Canyon is one of the most visited National Parks in the United States (only surpassed by the Great Smoky Mountains). In 2015, 5.5 million people witnessed the wonders of one of the largest

This article, written by aviator Wolfgang Langewiesche, appeared in the February 1957 issue of Reader’s Digest. I rewrote it for the blog in Simplified.
