9Grand Canyon, Arizona
One of the most awe-inspiring natural wonders of the world, the Grand Canyon attracts millions of visitors each year. Carved by the Colorado River over millions of years, this vast canyon stretches for 277 miles and plunges over a mile deep. The South Rim, accessible year-round, is the most popular area for visitors, offering panoramic views, hiking trails, and scenic overlooks like Mather Point and Yavapai Observation Station.
For a more remote experience, head to the North Rim or consider a hike into the canyon itself. Helicopter tours, rafting trips along the Colorado River, and mule rides offer unique ways to experience this geological marvel.
