Since 1997, Events include a variety of cultural activities and programs relating to the history of sheep ranching in Idaho and the Wood River Valley and the Basque and the Scottish heritage of the region. The sheep are the center of the Festival. But, the sheep knit together a cultural tapestry of concerts, workshops, presentations, personalities, dogs and horses. Join an authentic trailing of the sheep down Ketchum's Main Street on Sunday at noon as part of their annual migration to winter pastures. 1,500 sheep parade down Ketchum's Main Street with sheep ranching family members and herders headed south.
