"If any place has the power to inspire awe, it’s the Zion Narrows, southern Utah’s premier hike in Zion National Park. For 16 miles (26 kilometers), the canyon winds voluptuously through the crimson sandstone, in some spots stretching 2,000 feet (610 meters) high and narrowing to 20 feet (6 meters). Lush hanging gardens spring from the walls, stately ponderosa pines grow in nooks, and the water can turn a shade of turquoise that perfectly contrasts with the cliffs’ deep terra-cotta hues."
