You planned an outdoor day. It's raining. In Seattle this isn't a surprise — it's a reality that happens roughly 150 days a year. The good news: Seattle has excellent indoor infrastructure for families. Here's what to do when the weather doesn't cooperate.
Best Indoor Museums and Cultural Spots
KidsQuest Children's Museum in Bellevue is the right call for kids under 10. The three-story climbing structure in the center of the museum is the anchor — kids scramble through tunnels and pop out at different levels for 45 minutes straight. The water table area gets kids completely soaked (bring a change of clothes). The Build It workshop is a genuine engineering challenge for 9-year-olds. Toddler Town has a separate calmer area for under-3s. 4.5 stars. Budget ~$68 (2 adults × $16 + 2 kids × $16 + parking $4–6). Plan 2–3 hours.
Seattle Children's Museum at Seattle Center is an immersive hands-on museum where kids role-play as doctors, farmers, chefs, and explorers. Every surface invites touching and play. 4.3 stars. Budget $55–$65 (2 adults + 2 children, under 1 free). Plan 2–3 hours. The Seattle Center location means easy access to the Seattle Center Armory for lunch.
Volunteer Park Conservatory is a century-old Victorian greenhouse in Capitol Hill — five interconnected glass pavilions with tropical plants, giant cacti, and a fern house that feels like a scene from a nature documentary. 4.8 stars. Suggested donation ~$12 for a family of four. Plan 45–90 minutes. One of the best-value rainy day spots in the city.
Museum of Illusions - Seattle — mind-bending optical illusions, perspective rooms, and photo ops that defy logic. Kids love figuring out how each one works. 4.7 stars. Budget $70–$90 for two adults and two children. Plan 1–2 hours.
Kids Science Labs in the Green Lake area delivers hands-on science experiments — slime, chemistry, robotics, coding — that feel more like play than school. Every session is designed to make kids feel like real scientists. 4.8 stars. Budget $60–$80 for a family of four. Plan 1.5–2 hours.
Tropical Rain Forest Zone at Woodland Park Zoo is a warm greenhouse where free-flying birds pass at head height and camouflaged animals hide in the vegetation. Spotting the hidden species becomes a game for kids. Included in Woodland Park Zoo admission: ~$80 for a family of four (2 adults × $23 + 2 kids × $17). 4.9 stars. Plan 45–90 minutes as part of a broader zoo visit.
Tropical Butterfly House at Pacific Science Center has hundreds of free-flying tropical butterflies landing on kids' hands and shoulders. The warm, humid greenhouse environment feels like a rainforest, and kids immediately slow down and start whispering. Included in Pacific Science Center admission: ~$80–$95 (2 adults × ~$22 + 2 kids × ~$18). 4.7 stars. Plan 3–4 hours for the full Science Center visit.
Zoomazium at Woodland Park Zoo is a dedicated indoor nature-play space for under-7s. Treehouse, climbing structures, sensory play, hands-on nature discovery stations. One of Seattle's best facilities for the young crowd. 4.7 stars. Budget $40–$55 (zoo admission or Zoomazium-only tickets). Plan 1.5–2.5 hours.
Entertainment Venues
WhirlyBall is bumper car basketball with lacrosse scoops — impossible not to laugh, impossible not to get competitive. Laser tag and an arcade round it out. 4.8 stars. Budget $80–$120 for a family of four including game time, laser tag, and food. Plan 2–3 hours. This is the most unique rainy day option in Seattle.
Great Big Game Show Seattle (Downtown) makes your family actual game show contestants — live emcee, real buzzers, prizes. The format works for kids 8 and up who can read and have general knowledge. 5.0 stars. Budget ~$80–$120 (~$20–30/person). Plan 1–2 hours. Book in advance.
Big Air Trampoline Park in Auburn is inside the Outlet Collection shopping center — bigger and better-maintained than you'd expect. The foam pit airbag jump is the standout. 4.8 stars. Budget ~$100–$120 (4 × ~$27 + grip socks). Plan 2–3 hours.
The Jungle Gym in Burien has gymnastics equipment alongside open play — kids can actually work on tumbling skills in a guided environment. Toddlers love the soft equipment; bigger kids love the gymnastics apparatus. 4.7 stars. Budget ~$30–$45. Community feel, not a loud commercial trampoline park. Plan 1.5–3 hours.
Nick's Magnificent in Issaquah has extended evening hours (until 9 PM Fri–Sat), a real café with actual food, and good sight lines for parents. 4.7 stars. Budget ~$30–$50 plus café costs. Plan 2–3 hours.

The Ridge Activity Center in Bothell has laser tag as its main draw — actually designed around it rather than as an afterthought. Also a gym and various programming. 4.7 stars. Budget ~$40–$60 for a family of four with 2 hours of activity. Activity-dependent pricing: laser tag typically $8–12/person/session.
