The event is from 11am-4pm
Santa Claus will be there from 12pm-2pm, along with art projects, cookies, music, and more.
If you have a third grader in Fresno Unified School District, they are likely to have a piece of artwork in the student exhibition ART OF THE WORLD. (Keep in mind most of the pieces are in binders-so don't make this the only reason you come.)
Naturally, the museum is free of admission during the event, so it's a good time to get your kids in for free, especially if you have a big family. It will be crowded, so just mentally prepare for that. It's a great event and worth it.
