Wegmans Wonderplace is a paradise for toddlers, preschoolers and kindergartners. A Smithsonian Castle play structure with slides dominates the room, with artifacts from the museum’s collection housed inside, such as a Civil War-era military band E-flat fluegelhorn (complete with kid-centric placard). A scaled-down version of Julia Child’s kitchen allows kids to use replicas of Child’s pots and pans, and a play market provides their recipe ingredients. Next door is the elementary-to-middle schooler focused Spark!Lab, which brings STEM inventions to life through hands-on learning. Visitors can serve as inventors of vehicles, devices and even musical instruments. Constitution Avenue between 12th and 14th streets NW. Open daily (except Tuesdays). Free.
Tweens and teens will be drawn to an array of interactive exhibits that are every bit as exciting as an iPad game. The subject matter at this museum, located a block south of Verizon Center, is divided into three sections — Earth Lab, Life Lab and Idea Lab — and all areas focus on the connections among science, technology and community. 525 E St. NW. Open daily (except Tuesdays). $5; students $3.
On name alone you might think this Smithsonian museum’s subject matter is too dry for children. It’s not. In the “Systems at Work” exhibition, kids can sort packages by throwing them, and craft their own stamps and postcards. They also can “train” to become a member of the United States Postal Inspection Service. Little ones will love climbing all over mail transportation exhibits, from a Pony Express carriage to a mail train. 2 Massachusetts Ave. NE. Open daily. Free.
Entering this Dupont Circle mansion (actually five connected rowhouses) and embarking on a scavenger hunt through its many staircases, winding hallways and secret doors is like walking into an episode of “Scooby-Doo.” This museum-slash-hotel contains more than 100 themed rooms packed with eclectic collections of objects (all of which are for sale). Rosa Parks stayed at the mansion; visitors can explore her favorite areas, memorabilia and hear stories about the civil rights activist from H.H. Leonards, the mansion’s founder who is generally on-site. 2020 O St. NW. Open daily. $15 online, $20 at door. Themed tours cost extra.
Housed within the Davis Library in Bethesda, the KID Museum offers drop-in, always changing exploration sessions for elementary and middle schoolers on weekends.

Open Saturday-Sunday. $8; memberships available. Sure
Next door to the Maryland SoccerPlex in northern Montgomery County sits the Discovery Sports Center, where sports-minded kids from elementary to high school can drop in and join a game.

Since 2009, this family haven has been a favorite of young kids and parents looking for a place to play on winter days. (It’s usually open on snow days.)

Open Monday-Saturday. $9; 11 months and younger free.
Instead of scaling a faux rock face, how about climbing an indoor replica of Mount Rushmore? The Lincoln Memorial? Or a giant bookcase, a la “Honey I Shrunk the Kids?” In addition to 75 creatively themed walls that vary in difficulty (so even courageous 2-year-olds can climb), the harnesses and ropes are adjusted especially for kids. Although kids age 12 and younger must be supervised by a parent or caregiver, ClimbZone’s hydraulic auto-belay system allows kids to descend easily on their own, without relying on an adult to lower them. Preschoolers will enjoy the inflatable slides and bounce houses. 13200 Mid Atlantic Blvd., Suite 130, Laurel. Open daily. $25; ages 2-5 $12; children younger than 2 free.

Open daily. $12; seniors $11; children younger than 2 free.
Crawlers, new walkers and industrious young preschoolers tired of traversing the couch will be thrilled with the array of soft play equipment at the indoor play areas at the Arlington Mill, Fairlington and Lubber Run community centers.

Dinwiddie St.; Fairlington, 3308 S. Stafford St.; Lubber Run, 300 N. Park Dr., Arlington. For hours, go to parks.arlingtonva.us./programs/tots. Free.
Babies and toddlers need to get out of the house for play, too, and Nook is designed just for them. This tranquil, modern space is divided into separate nooks for art, music, reading, building, climbing and sensory play, as well as an area especially for infants. Passes are good all day, so families can head home for a nap and then come back refreshed for more play. 5649 Lee Hwy., Arlington. Open daily. $20; caregivers and babies younger than 1 free.
The latest addition to the indoor bounce house genre, Leesburg’s Atomic Trampoline has wall-to-wall trampolines, a foam pit, dodge ball and slamball courts.
