Note from AFAR: After a three-year renovation, the museum is open once again, now with 7 floors and 7 miles of gallery space.
One of my favorite museums in San Francisco is the Museum of Modern Art (SFMOMA). In addition to the main exhibition, the museum always displays supplementary art and photography exhibitions, which are almost always amazing. There are five floors, every floor beaming with innovative, contemporary art. Modern art spans a wide domain, so there is something for the art lover at every age. One of the crowning glories of the museum is the architecture itself, so you'll be amazed even before you step in. It's easy to maneuver through the rooms and passages for hours and hours.
