Visiting museums can get expensive, especially for families. However, many local museums and attractions offer FREE admission every month — some even offer special activities on those days. The free days are funded, in part, by taxes collected through the Science and Cultural Facilities District and/or donations from generous sponsors. Because free days are so popular, you are wise to reserve tickets in advance if the attraction has a timed-entry policy.
While admission is FREE, special exhibitions or other add-on activities may incur a fee. Dates and times may change, so always double-check before you visit.
