Olympia Harbor Days in Olympia, Washington, is an annual festival in which tugboats return to the southernmost tip of Puget Sound for three days of entertainment, food, art, history, and a last farewell to the summer. Vintage, working and retired tugboats are moored at Olympia's Percival Landing. Many of them are open for tours on Saturday of the festival. At noon Sunday, the tugs leave shore to participate in the Annual Harbor Days Tugboat Races.
