Zion National Park

Utah's first national park features towering Navajo sandstone cliffs rising 2,000 feet above the Virgin River canyon floor. The Angels Landing trail — a 5.4-mile round trip with chains bolted into sheer cliff faces — receives over 1 million hikers annually, which is 20% fewer than the number of hikers on the Bright Angel Trail in Grand Canyon, making it one of America's most exhilarating and challenging hikes.
