We love fall (and the pumpkin spice that comes with it) as much as the next grown-up. But we admittedly get chills when we think about hunting down cold weather alternatives to outdoor play for our kids. Luckily, D.C. is home to some of the best indoor playgrounds in the country, created for the sole purpose of letting kids go wild. And the good news is that most of them offer a fun time for grown-ups, too. Click through the photo gallery to discover the best places to play indoors.

National Building Museum

The National Building Museum has turned itself into one of the city’s go-to spots for young families by featuring two awesome play spaces for kids (not to mention the enormous lobby hall that kids are encouraged to run freely in). The Building Zone, geared to the under-6 set features blocks, costumes, books, a sandbox, and a life-size “green” house. The Play Work Build exhibit (through Nov. 18, 2014), lets kids get busy building structures with Tinker Toys, Lincoln Logs, Bumpalow House, and Ringa-Majigs. Kids can also build—and knock down—their own structures virtually using an interactive wall.

What’s in it for you? These exhibits can be almost as fun for adults as they are for kids. Make sure to swing by the museum’s gift shop after the play is done to check out the cool toys, stationary and homegoods; by some accounts it’s the best museum shop in the city.
