No need to check the weather report. It’s cold. And it is, was, or will be snowing soon.

When you’re done climbing your own walls, head to these new play spaces in Brooklyn and scale theirs.

Klub4Kidz
Mr. and Miss Ants in Their Pants (ages 3 and up) will find an outlet for all that pent-up energy in the club’s impressive four-story play structure — a maze of tubes, slides, obstacles, and even a zip line. If that’s not enough to tire them out, an eighteen-foot rock-climbing wall should finish the job. 159 North 4th Street, between Bedford and Driggs Avenues (877-543-9558 or klub4kidz.com), $12 for one child; $20 for two children; additional $8 for rock-climbing.

Play
Akin to a sprawling basement rec room that city kids will never know, the center’s padded play area is strewn with bean bag chairs, easels, and ride-ons, making it perfect for the 5 and under crowd. Imaginations soar with a play kitchen, market, reading corner, and slide. All of this is set against a mural depicting a city block where kids and animals run wild — and the forecast is always sunny. 33 Nassau Avenue, at Dobbin Street (718-387-2071 or playspacenyc.com), $10 for a day pass.
