With its ever-changing and dramatic scenery of enormous proportions, the Grand Canyon is one of the world’s most spectacular landscapes. Its pine and fir forests, painted deserts, sandstone canyons, mesas and plateaus, volcanic and geologic features, the Colorado River, perennial streams, and waterfalls breathtakingly combine to form one of Earth’s greatest landmarks. The only one of the Seven Natural Wonders of the World to be located in North America, more than 4,000,000 people visit the canyon each year, making it the most visited national park in the United States.
