Learn how to make the most out of visiting The Getty Center with kids in Los Angeles. 

Maybe you and your kids have squeezed every last drop of fun from Travel Town or have soldiered through every stroller-friendly hike in LA within driving distance. You're itching for a dose of culture that doesn't include a kiddie museum, stuffed animals, or squeaky toys (not that there's anything wrong with them); but at the same time a real museum seems daunting. Should you brave LA's iconic Getty Center? Short answer? You definitely should. 

The Getty Center is one of the must-do 100 free things to do in Los Angeles with kids. Don't forget, there's a whole other Getty museum in Los Angeles, and you can check out The Getty Villa with kids, too.

The Hallett Nature Sanctuary is one of the most beautiful hidden gems in Central Park, and it's a perfect NYC space to explore with kids for a moment of peace that transports you out of the city.
