Grand Canyon National Park preserves one of the world's most spectacular natural wonders - a mile-deep chasm carved by the Colorado River over millions of years. This UNESCO World Heritage Site showcases nearly two billion years of Earth's geological history in its colorful rock layers. The South Rim, open year-round, offers iconic viewpoints like Mather Point and Yavapai Observation Station, while the more remote North Rim provides a different perspective from May through October. The canyon stretches 277 river miles long, up to 18 miles wide, and reaches depths of over a mile. Beyond the breathtaking vistas, the park protects five of the seven life zones and three of the four desert types found in North America, supporting over 1,500 plant species and 400 animal species. Whether visitors come for sunrise at Hopi Point, hiking the Bright Angel Trail, or experiencing the Colorado River, Grand Canyon offers a humbling encounter with the immense power of geological time.
