Angels Landing, known earlier as the Temple of Aeolus, is a 1,488-foot (454 m) tall rock formation in Zion National Park in southern Utah. A trail, cut into solid rock in 1926, leads to the top of Angels Landing and provides a spectacular view of Zion Canyon. The trail to Angels Landing is 2.4 miles (3.9 km) long. It begins at the Grotto drop off point on the park's shuttle system. It roughly follows the path of the Virgin River for some time, slowly gaining elevation in sandy terrain. As the trail gets steeper and leaves behind the river, it becomes paved. After a series of steep switchbacks, the trail goes through the area between Angels Landing and the Zion Canyon that is a gradual ascent. Walter's Wiggles, a series of 21 steep switchbacks, are the last hurdle before Scout Lookout. Scout Lookout is generally the turnaround point for those who are unwilling to make the final summit push to the top of Angels Landing. The last half-mile of the trail is strenuous and littered with sharp drop offs and narrow paths. Chains to grip are provided for portions of the last half-mile to the top at 5,790 feet (1,760 m).
