Play areas and activities include an obstacle course, a soft play area, a rainbow "climb and slide", an ice cream truck, ball pit, small wood cube pit, a "hideout", swings and beehive cubbies. And there's more to come! There's an on-site cafe where you can grab a coffee or juice and chill while the kids play.

This 4,500-square-foot creative play wonderland in the heart of Williamsburg, (for kids six and under and you must book your two-hour play slot in advance) iis loaded with exhibits—everything from the "Red Hot Fire Truck" (complete with hoses that spray real water) to "Graffiti Room" (a fully padded room for dancing and tumbling) to "How to Feed Your Dragon," (which houses four colorful, 15-foot-tall dragons). New additions to the space include a Pet Shop and Tea Salon.

The Heimbold Family Children's Play and Learning Center, located inside the Scandinavian House, is only open to the public on Saturdays from 10 a.m. to 5 p.m. (for a modest fee), but it's worth the trip.

Kanga's Indoor Play Center is huuuuge! Designed for kids ages 1 to 11, Kanga's offers tons of diversions for kids while the parents grab some food and coffee at the on-site cafe. There’s a giant jungle-gym style crawl and play structure, numerous Merry-Go-Rounds, an inflatable bouncy house, huge ball pits filled with plastic balls, a separate toddler area for the younger kids (ages two and under), and more—including a twirling teacup ride.

Bounce 'N Play's features include a special toddler area for younger patrons; an oversized playground for children three to 13 years old, and a jungle gym, slides, play sets and a rock climbing wall for older ones. But what really won us over were the specially-tailored open play sessions, like one for kids ages six and under, one for all ages, and one for the whole family on Wednesday evenings (which includes a buffet!). It also frequently hosts Open Bounce when school is out.

The Little Athletes Exploration Center is a great Chelsea indoor play space. Located in Chelsea Piers, the center has drop-in play for kids ages six months to four years old. We love the two-story climbing gym filled with sensory play items, and the ball pit that we so wish we could dive into ourselves. Everything is padded and soft, so your wee ones can go wild without hurting themselves. The center is generally open seven days a week, but we suggest you call in advance for the daily schedule,

PLAY, located at the intersection of Williamsburg and Greenpoint, across the street from McCarren Park, really delivers. In fact, we named it one of the best play spaces in the world. The 3,000-square-foot facility has all the ingredients of a kid-approved good time: a sizable tumbling gym for mastering the somersault, a music and arts studio to get creative juices flowing, loud noisemakers that would never see the light of day in your apartment and a locally-made playset with slides.

Have your ninjas-in-training turned the sofa into a booby-trapped bridge one time too many? Set them loose on the indoor playground at Kids ‘N Shape that specializes in unstructured fitness play—or, to put it another way, all the cool stuff you wish you got to do in P.E. class. Don’t be surprised if your high-energy charges are torn between wobbling around the bounce house, racing through a 40-foot inflatable obstacle course, diving into a ball and foam pit, or whizzing down a zip line.
