San Francisco, California
San Francisco contains a large Irish-American population, thanks to the Gold Rush of 1849. Today it holds annually the largest St. Patrick's Day festival on the West Coast. While visiting the Golden Gate City, Catholics won't want to miss a chance to visit the National Shrine of St. Francis, where relics of St. Francis, St. Clare, and St. Anthony of Padua -- along with many glorious works of art -- will make for a full day of exploration.
