Two less-visited museums offer tranquility. Patrons of modern and contemporary art hang out at the Hirshhorn Museum. Its sunken garden isn't noticed by many, but it's one of the prettiest spots. Inside the doughnut-shaped building, edgy exhibits test your ideas about art.
The Freer Gallery of Art mixes American and Asian works. Highlights include James McNeill Whistler's Peacock Room. The best-kept secret may be its quiet courtyard, ideal on a spring day.
