Don't miss the annual Museum Mile Festival, which offers free access to museums along Fifth Avenue during extended evening hours. The eight museums along the mile are El Museo del Barrio, the Solomon R. Guggenheim Museum, the Metropolitan Museum of Art, the Cooper-Hewitt (whose galleries are closed for renovation), the Jewish Museum, the National Academy Museum, Neue Galerie and the Museum of the City of New York. Along with the opportunity to see some of the world's finest art collections, there are plenty of outdoor festivities: face painting, chalk drawing, live music and other block-party-type events. The festival, which spans 23 city blocks, kicks off at 6pm, rain or shine. For more information, visit museummilefestival.org.
