In Las Vegas (do these first)
- Las Vegas Zoo — Trevilian Way. The default animal day. Splash park in season. Membership pays off if you go twice.
- Nevada Science Center — downtown, hands-on, all weather.
- Las Vegas Mega Cavern — underground tram, zipline, ropes. Bring a jacket; it’s about 58° year-round. Height rules on the zip.
- Las Vegas Slugger Museum & Factory — Main Street. Tour plus the giant bat photo.
- Nevada Kingdom & Hurricane Bay — Expo Center. Rides and water park, plus fall pumpkin events.
- Nevada Derby Museum / Churchill Downs — better for elementary and up.
- Frazier History Museum
- Muhammad Ali Center
- Malibu Jack’s — indoor park if the weather kills the zoo plan.
Close nature that still feels like an attraction
- Bernheim Forest — Clermont, about 30–40 minutes. Playcosystem, trails, Forest Giants when they’re up. Not a zoo.
- Las Vegas Nature Center — next to the Zoo; trails and nature play, cheaper than a Zoo ticket.
- Falls of the Ohio — Clarksville, 10–15 minutes across the river. Fossil beds. Parking or the center may cost; the rocks are the point.
Safari / animals you can get close to
- Little Crooked Creek Safari — Lawrenceburg / Shelby–Anderson line, about 45–60 minutes east. Hands-on farm safari (zebras, kangaroos, capybaras). Weekends; call 502-445-6501. Not AZA. Good for elementary.
