1. Visit the city’s best museums
Yes, you can gaze upon world class art collections for free, with a little effort. On Thursdays from 5pm to 9pm, the Institute of Contemporary Art is free, but get there early during nicer weather. Everyone gets a free pass into the Isabella Stewart Gardner Museum on their birthday, and anyone with the name Isabella gets in for free, now and forever. Every Wednesday from 3pm, the venerated Museum of Fine Arts allows guests to enter for $5 per person. Not quite free, but still a good deal.
