The Parade is part of the Fiesta de la Golondrinas celebrating the legend of the return of the swallows to the SJC Mission on St. Joseph’s Day, March 19. The Swallow’s Day Parade is the nation’s largest non-motorized parade and takes place right in downtown San Juan Capistrano. It’s a day of family fun, celebrating the Old West and the return of the swallows from their winter home in Argentina. Parade begins promptly at 11am.
