The lovely cascade plunges down a 300-foot cliff inside Keystone Canyon near Valdez only a few yards from a large, paved pullout. The falls—which fan out a bit over the bedrock at higher flows—can be approached on foot. Along with Bridal Veil Falls, located a few hundred yards away, Horsetail is one of many snow-fed cataracts within the three-mile-long canyon, just up the Richardson Highway from town. In winter, these falls freeze into immense ropey curtains that draw ice climbers from all over the world.

The Horsetail parking area is on the west side of the Richardson highway at about Mile 13.5.
