Bank of America’s Museums On Us program returns for its annual free museum weekend in September 2026. If you’re a BofA cardholder, you and a guest can visit participating museums across the Bay Area without paying admission—perfect for catching that exhibition you’ve been meaning to see or discovering a new cultural spot. This is one of the best deals on the local culture calendar, so grab your card and plan ahead. Most major Bay Area institutions participate, from the de Young to the Exploratorium.
