Three agencies run the DC area's best family parks — Fairfax County, NOVA Parks and Montgomery Parks — and each prices by its own definition of a local, per ride, with no unlimited wristbands anywhere. Clemyjontri is the one every family should know. Where the fee depends on where you live, we say so.
Updated October 21, 2026 · refreshed weekly
Clemyjontri in McLean is the region's default park for mixed-ability groups, and it is free to enter and to park. Only the carousel and the train cost anything.
A “boundless” playground built for mixed-ability groups: ramps up to the elevated play components rather than steps, rubber safety surfacing instead of mulch, lowered monkey bars, sensory-rich equipment and four color-themed play areas.
Park and parking are free. The carousel and the trackless train are $4 per person per ride on weekdays and $5 at weekends and on holidays, charged per ride with no unlimited option.
Mixed-ability groups, children who use wheelchairs, and a two-year-old on an ordinary Tuesday
Four places here charge nothing at all, and between them cover a wetland boardwalk, a conservatory, lotus ponds and a wooded island.
A half-mile raised boardwalk through a beaver-created wetland out to an observation tower — the best introduction to nature in the region for a three-to-ten-year-old, with more than 200 bird species recorded.
Free — no admission and no parking fee
Three-to-ten-year-olds, and anyone pushing a stroller who still wants a real wetland
Free public gardens with a conservatory and a Children's Garden on site.
Free
A warm indoor hour in winter, with a garden to run in afterwards
Lotus ponds in Northeast DC that bloom through the hot humid summer months.
Free, and no entrance pass at all
Summer mornings — the blooms are the whole point
A free, wooded Park Service island in the Potomac, walkable from Rosslyn.
Free
Walkers — leave the car in Rosslyn if you can
Two agencies use two different definitions of local, and conflating them is how a day out goes wrong. Rides are never included in anything.
A county lake park whose one-third-scale replica steam engine runs a 1.75-mile loop in about ten minutes, alongside a carousel, a tour boat and mini golf.
Train $5 weekdays / $6 weekends per person per ride; carousel $4/$5; tour boat $4/$5 with under-twos free; mini golf $9/$10 for adults and $8/$9 for juniors and seniors.
Train-obsessed preschoolers — on a weekday if you live outside the county
A 95-acre stroll destination with the Korean Bell Garden, lakes and gazebos on paved but rolling paths.
$9 for ages 18–59, $5 for ages 6–17 and 60-plus, free for 5 and under — one price for residents and non-residents. A family of four with two school-age children is $28, and the $65 family membership pays for itself in two or three visits.
Walkers and stroller pushers — the paths are paved, though they roll
You promised a playground — there isn't one
All three park-run water parks ran from May 23 to Labor Day, September 7, in 2026. The resident and non-resident gap is wider here than anywhere else in this guide.
A county water park with the Rattlesnake Lazy River, the Tenderfoot Pond tot pool, slides and tunnels.
Fairfax County residents pay $17.25 weekdays and $18.25 weekends over 48 inches, $14.25/$15.25 under 48 inches, free at two and under. Non-county residents pay a flat $20 weekday and $22 weekend with no under-48-inch discount.
Fairfax County residents, and anyone who came for a lazy river
You live outside the county with a small child — this is the biggest resident gap in the guide
The cheapest and most toddler-friendly of the three: a baby pool, a sand play area and a 500-gallon dumping bucket beside 230-foot and 170-foot slides.
$12 weekday and $16 weekend at 48 inches and over, $9.50/$12 under 48 inches, free under two, and $7 after 4pm on weekdays. Registered Bull Run campers get in free.
Toddlers, and anyone who can go late on a weekday for the $7 rate
A wave pool, seven slides and a Paradise Play structure built for ages 3 to 12.
$17.50–$20.50 at 48 inches and over. The $25 in-season Play All Day pass adds mini golf and a batting cage, and is the best-value ticket of the three.
Ages 3 to 12, arriving early

Yes, and so is parking, for residents and non-residents alike. Only the carousel and the trackless train cost money, at $4 per person per ride on weekdays and $5 at weekends and on holidays. There is no unlimited-ride wristband.
Only Burke Lake and Bull Run. Burke Lake charges non-Fairfax-County residents $12 per car at weekends and on holidays from April through late October, and nothing on weekdays. Bull Run charges everyone $8 to $14 by residency and day.
The half-mile boardwalk and the one-mile paved hike-bike trail are; the two-mile interpretive trails are natural-surface. Plan around two things: no dogs on the boardwalk, and the only restrooms are in the visitor center, which closes Tuesdays.
At some, and the systems differ. Fairfax County Park Authority prices by county residency, so Burke Lake's weekend gate fee and the Water Mine's admission both change. NOVA Parks prices by member jurisdiction. Meadowlark charges one price for everyone.
