Los Angeles has tons of great places to entertain children of all ages and we know we've missed some. Add any places to go in LA for kids that we may have missed to the bottom of the list.
This is my very favorite place to take the kids. Every weekend, I would say, and it's always different. Pick a trail from one of the hundreds in the hills. Park by the tennis courts and head up the hill. Park in Bronson and hike up to see the old quarry (known as the "Bat Cave") where they filmed the iconic shot of Batman's car entering or leaving his lair. Go around to the valley side and you can put the kid on a pony for 2 bucks or ride the little cheeseball train for another 2. Have a picnic at any of the zillion areas, complete with playgrounds. Best of all, it'e free and your kids get to be outside. see more on Griffith Park
Santa Anita Park
This is one of my favorite places to take the kids, but its not an every-weekend kind of thing. The ponies don't run here year-round, they switch off with Hollywood Park - which is a slum, and gross, and not somewhere to take your kids. This is a beautiful, old-school race track and they have a fantastic infield - which is exactly where you should go with your kids. Pick a weekend they are running a big event race like the Breeders Cup. It's great for adults too (Gambling! Beer tents!) and you can camp out on the grass right by the fence and watch the horses race literally feet away. There's a huge playground for the kids to play on between races - or for when they lose interest in horses running. And during these events there are tons of food tents and live music. It's a really great time.http://www.santaanita.com/
California Science Center
Sure, their Ecosytsems exhibit is great fun for the offspring, but what CSC really has is the Space Shuttle! A whole space shuttle parked next to it! Hard to beat that, really. This place is technically free, tho they do ask for donations. It is a terrific way to spend a good chunk of the day with the kids, and I have yet to meet a kid that doesn't love it. There's also an Air and Space Gallery in another building nearby (the one with the giant jet fighter bolted to the roof) that is full of dated, hilarious exhibits... but also a fun (empty) space for them to run around in and look at ACTUAL modules from a couple of the moon missions which are cool as hell.www.californiasciencecenter.org
This is one of the most Los Angeles things you can do with your kids in this city. The views are spectacular and the observatory itself is both free and neat. If you want to spend money on the planetarium show, you can, but otherwise, wander around in exhibits both old and new. A fun way to make an afternoon of it is to park at the bottom of the hill and walk up one of the many trails, getting a great view the whole way. Once you are done inside and feel ambitious, keep climbing up to the top of Mt Hollwood that looms over the place. Its not a long hike and you get a 360 view of the entire Metropolitan area, including the Valley side, too.
Note that coming on a weekday is infinitely preferable, unless you really want to know what it's like to feel crushing rage and despair because parking is literally impossible on a weekend and it's a frigging mob scene even if you do find parking. If you must visit on a weekend, take the shuttle from Hollywood/Highland or that parking lot over by the Zoo.
