What could be better than finding yourself almost alone as you stroll through the galleries of a museum? Impossible? Not so in Paris, Just go to one of the late night opening evenings, when most people have left the premises.
Late night and even all-night opening hours enable visitors to view works of art, with perhaps fewer crowds. The Palais de Tokyo is open all year long, until midnight.
Every year, during the highly-popular La nuit des musées, many Parisian museums open all night.
