Free Admission at Cummer Museum, Twice Monthly

Why it's worth it: The Cummer Museum typically charges $15 for general admission. No purchase needed.

General admission to the Cummer Museum of Art & Gardens in Jacksonville costs nothing on the first Saturday of each month from 11 a.m. to 4 p.m., and on the third Tuesday from 4 to 9 p.m. Young children also get in free every day, though the age cutoff isn't specified, so check the museum's site before you go. No signup is mentioned, but confirm hours and any special-exhibit exclusions with the museum.
