Love museums, but the prices make you think twice? If you have a large family, those tickets add up fast—which is particularly frustrating if you then need to beat a hasty retreat to avoid a meltdown. SoCal has some great museums that have free general admission every day of the year, including The Getty, California Science Center, and The Broad. As for the rest of them (once kids are old enough to have to pay), many LA and OC museums have monthly or even weekly free days or evenings, and we have collected a list for easy reference. Go ahead, bring the extended family, meet friends, or check out a place you have never been before—all for just the price of parking or Metro tickets. And if there's a meltdown? At least it's free.
