Nice quiz. I like Grand Canyon National Park more, but I am okay with Yosemite National Park and Yellowstone National Park. I went to Desert View, Bright Angel Trail, South Kaibab Trail, Hermits Rest, Grandview Point Mojave Point, and The Abyss during my stay in the wonderful Grand Canyon National Park. I highly recommend people to go to Grand Canyon National Park. The canyon is one mile deep at its deepest and 18 miles wide at its widest. At first it was a national monument. In 1919, 6 weeks after Theodore Roosevelt died, it turned into a national park. It is the only national park which encompass one of the 7 natural wonders of the world. Grand Canyon National Park is the second most visited national park.
