It doesn't rain often in Las Vegas, but when it does, your outdoor plans disappear fast. Desert rain also means flash flood warnings, so you're not just dealing with wet kids — you genuinely need to be indoors. The good news: Las Vegas has more indoor family options than almost any other city. Here are 34 that work when the weather doesn't.
Best Indoor Museums and Cultural Spots
Museum of Illusions — $100–$120 for a family of four. The Ames Room makes kids shrink and grow, the tilted room makes them wobble and laugh, and every exhibit is interactive and photo-friendly. Strip location, 1–1.5 hours. Even kids who don't like museums will bounce from room to room here.
Infinity Museum — $80–$100. Infinity rooms that extend forever using mirrors and colored light. Kids want to stay in each room far longer than you'd expect. Open until 10 PM every day, so it works as an evening option too. 4.9-star rating.
Atomic Museum — $50–$70. Stand next to a decommissioned nuclear weapon casing. Older kids and teens who've studied WWII or the Cold War will feel history becoming real. Kids under 6 are free. 1.5–2.5 hours.
Las Vegas Science & Natural History Museum — $45–$60. The animatronic T-Rex moves and roars — a genuine gasp moment. A whale skeleton hangs overhead. The Ancient Egypt room with mummies keeps tweens engaged. 2–3 hours. No on-site food, so bring snacks.
Dinosaur Outpost — $60–$80. Life-size replicas you can touch, hands-on fossil dig stations, and interactive touch screens. About $15 per person. Kids under 2 free. 1–2 hours.
Origen Museum — $40–$60 (included with Springs Preserve combo). Interactive water and geology exhibits. The museum portion is indoor, though Springs Preserve has outdoor areas too. Best for a partly rainy day when you can duck between buildings. 1.5–2.5 hours.
CSN Planetarium — $20–$30. Full-dome planetarium at community college pricing ($5–$8 per person). Only open Friday evenings and Saturdays. Book ahead — shows sell out. 1–1.5 hours per show.
Entertainment Venues
These are your heavy hitters for burning off energy indoors.
The Adventuredome Indoor Theme Park — $200–$260 for all-day passes. A five-acre climate-controlled dome inside Circus Circus with roller coasters, a log flume, and carnival midway games. This is the nuclear option for a rainy day — 3–5 hours, all indoors. All-day passes are better value than per-ride tokens. Eat before you enter.
Ninja Kidz Action Park — $80–$120. Obstacle courses, ninja warrior training, laser tag, trampolines, and foam pits. Kids who watch the YouTube channel feel like they're stepping into the show. 2–3 hours. 4.9-star rating.
K1 Speed Indoor Go Karts — $120–$160. Electric go-karts at real speeds. Junior drivers (48"–58" tall) ride with an adult. Post-race lap time rankings on a big screen make this competitive and fun. 1–2 hours.
Flip N Out Xtreme - Henderson — $80–$120. Trampolines plus laser tag under one roof. Kids switch between the two when they get tired of either. 2–3 hours.
Sky Zone Trampoline Park — $80–$120. Interconnected jump courts, foam pit, dodge ball courts, climbing wall, and ninja course. The dodge ball courts are particularly popular with kids 8+. Bring your own grip socks. 1.5–2.5 hours.
Slime Kitchen — $80–$120. Custom slime-making sessions inside Fashion Show Mall on the Strip. Choose your base, mix in glitter and scents, take your creation home. 45–90 minutes. Adults watch free.
Sphere — $300–$400+. The most technologically advanced entertainment venue in the world. Floor-to-ceiling wraparound LED screen, haptic seats, scent effects. A splurge, but a rainy day might be the excuse you need. Consider whether your kids are old enough to appreciate it. 2–3 hours.
