SoCal Museums Free-For-All 2026 is Sunday, Feb 22nd. As of writing this, there doesn't seems to be an official web-site for it, we've got a list over at Time Out, but be sure to check each museum's site for details. Like if you still need to make reservations.
Quite a few places to check out, so take advantage of it. Though many museums have free evenings and such at least once a month.
