Rain in DC is frustrating specifically because the National Mall — the thing most families came to see — is outdoors. A rainy day isn't a ruined trip. It's a forced pivot to the indoor side of DC, which is genuinely excellent. Here's how to fill an entire day indoors without losing your mind.
The Full-Day Plan
A solid rainy DC day runs about 8 hours of activity time. Here's how to structure it.

Morning: High-Energy First
Start with something physical before kids hit museum fatigue. This is the key move that makes rainy days work.
Hyper Kidz Alexandria opens early and runs 2–3 hours for a family with real energy to burn. 4.9 stars from 5,000+ reviews, $50–70 for a family of four. It's a structured indoor play facility — not just a bounce house, but a real operation. Hyper Kidz Rockville matches it at 4.9 stars from 2,442 reviews if you're staying on the Maryland side.
For something that feels more special, Great Big Game Show DC in Georgetown is the single best rain-day splurge — a live game show where your family are the contestants. 5.0 stars, 2,500+ reviews, $80–120 for four. It runs 1–2 hours and requires advance booking. Book this before your trip. Georgetown parking is brutal — Metro to Foggy Bottom and walk.
FUNBOX Bounce & Party Center in Bowie (4.7 stars) is $50–70 and good for 2–3 hours. Magic Ground runs $60–80 and has a dedicated toddler section plus multi-level play structure.

Late Morning: Escape Rooms (Best for Ages 9+)
If your kids are old enough, escape rooms are the rainy-day move. You're indoors, engaged, and genuinely can't think about the weather because you're too busy solving puzzles.
The Escape Game DC (Penn Quarter) is the gold standard — 5.0 stars, $100–140 for four people, 1.5–2 hours including briefing and debrief. This is the best escape room chain in the country, and the DC Penn Quarter location is excellent. Book it. Weekday slots have better availability.
Escape the Room DC (Penn Quarter) is a strong alternative — 4.9 stars, $100–140 for four ($25–35/person). Both locations are in Penn Quarter, making them easy to combine with lunch at the cluster of restaurants on 7th Street.

Afternoon: Science and Museum Mode
After lunch, the kids' energy has shifted — they're ready for something to look at, not just do.
Maryland Science Center in Baltimore is worth the 45-minute drive on a rainy day when your DC outdoor plans are wrecked anyway. It's a full day by itself — three floors, IMAX, and a planetarium. $80–120 for a family of four. Plan 3–4 hours. This is one of the best science museums on the East Coast.
Staying in DC? Children's Science Center Lab at Fair Oaks Mall runs structured 2-hour science sessions, $40–60 for a family. Wegmans Wonderplace in the National Museum of American History is free and designed for kids. These work as an affordable afternoon anchor.
Glen Echo Park Aquarium — small, intimate, $30–50 for four. Not the National Aquarium's scale, but kids get closer access and there are no crowds.
National Aquarium in Baltimore is the premium choice — $110–160 for a family of four (adults ~$45, kids ages 3–12 ~$35). One of the best aquariums on the East Coast. Plan 3–4 hours. Combine with the Maryland Science Center for a full Baltimore day if weather is really ugly.

Afternoon Alternative: Indoor Adventure Parks
If the kids need more physical activity rather than museum time, afternoon works for trampoline parks too.
Flight Adventure Park Springfield — $60–100 for four, 2–3 hours, multi-attraction indoor adventure. Get Air Trampoline Park in Alexandria — $60–80, 1.5–2.5 hours. Urban Air Trampoline and Adventure Park in Largo — $60–100 depending on pass. Off Limitz Adventure Park at Potomac Mills — $60–80.
Scramble Alexandria (4.4 stars) and Scramble Parkour are both parkour gyms — $50–80 for a family. These develop real skills; your kid will come home showing off.

Rain-Friendly Zoo Options
The National Zoo is technically outdoor, but Small Mammal House and Amazonia are both indoor exhibits worth visiting even in rain. Free admission. You'll get wet walking between them, but the exhibits themselves are covered. The Zoo's Great Indoor Flight Cage gives another dry option.
Palisades Recreation Center and Petworth Recreation Center Playground both have indoor components — free or nearly free. Not glamorous, but genuinely functional.
---
Immersive Experiences
Bubble Planet runs $60–100 for four ($15–25/person) and takes about 1–1.5 hours. It's a walk-through installation built around giant bubble structures. Weird and wonderful; kids who've been in museums all day will find it genuinely refreshing. Book in advance.

Sample Rainy Day Timeline
| Time | Activity | Cost (family of 4) | |------|----------|-------------------| | 9:00–11:00 AM | Hyper Kidz or FUNBOX (physical warm-up) | $50–70 | | 11:30 AM–1:30 PM | Escape Room (Penn Quarter) | $100–140 | | 1:30–2:30 PM | Lunch near Penn Quarter | $40–60 | | 3:00–5:00 PM | Maryland Science Center or Children's Science Center | $40–120 | | 5:30 PM+ | Dinner and call it a day | — |
Total: $230–390 for a full splurge rainy day. Cut the escape room and Maryland Science Center and replace both with free Smithsonian options and you're under $100 for the day.
Rain in DC is genuinely not a problem. It's a different trip.
