Each spring, millions of people descend upon Washington, D.C., to participate in the National Cherry Blossom Festival. Dubbed “the Nation’s Greatest Springtime Celebration,” the outdoor event honors the 1912 gift of 3,000 cherry trees from Mayor Yukio Ozaki of Tokyo to the city of Washington, D.C. You can see them in three locations: Tidal Basin, East Potomac Park and on the Washington Monument grounds. Peak bloom occurs in March and April, with special events (including a parade) happening across the city.
