8Grand Canyon National Park, Arizona
The Grand Canyon is one of the world’s most awe-inspiring natural wonders, a massive chasm carved by the Colorado River over millions of years. Stretching 277 miles, the canyon plunges to depths of over a mile, revealing layers of ancient rock in colors that shift with the sunlight. Visitors can marvel at the views from the South Rim, which is open year-round, or the quieter North Rim, accessible only during warmer months. Activities range from hiking down into the canyon to thrilling helicopter tours and river rafting adventures.
