Trailing of the Sheep Festival in Hailey
Every October, roughly 1,200 sheep are trailed down Main Street in Ketchum as the centerpiece of the Trailing of the Sheep Festival, a five-day celebration of Idaho's Basque, Scottish, and Peruvian sheepherding heritage across Sun Valley, Ketchum, and Hailey. Founded informally in 1996, it now draws more than 25,000 visitors for a folklife fair, wool classes, and championship sheepdog trials.
Sheep have grazed the mountains above Idaho's Wood River Valley since the late 1860s, when rancher John Hailey brought in the region's first flocks.
