10. Lied Discovery Children's Museum
This museum houses more than 100 interactive exhibits about science, art, and culture. This fall, the whole kit and caboodle moves into posh new digs in Symphony Park, reopening as the Discovery Children's Museum, with new exhibits including Water World, Toddler Town, Fantasy Festival, and Young at Art.

9. Hoover Dam
There's a reason that, more than 75 years after its completion, Hoover Dam still draws nearly a million visitors each year. The tour guides lead an exploration through the Powerplant, the internal passageways of the construction marvel, and the Observation Deck.

8. Vegas Indoor Skydiving
Skydiving without the danger? Well, thanks to the Vertical Wind Tunnel, trampoline floors, and padded foam walls, that’s what you get at Vegas Indoor Skydiving, and anyone over 40lbs can join the fun.

7. Blue Man Group
We all know the Blue Man Group, and as long as your kids are at least three years of age, it's fun for all ages indeed. Just don't forget to wear a poncho and earplugs!

6. Pole Position Raceway Indoor Karting
With the height requirement at 48 inches or taller, these electric (not gas) go-karts are not for the teeny tots, but kids around seven or older will love taking part in the Driving Clinic and Youth Racing Camp offered at this indoor facility. 

5. Qualify as a Junior Ranger at Red Rock Canyon
Sure, Red Rock Canyon National Conservation Area is beautiful and picturesque, but adventurous youngsters will get a real kick out of becoming qualified as a Junior Ranger (complete with a badge and certificate) by partaking of the activities (broken-down by age—six and under, seven to nine, and ten and over) in the downloadable Junior Ranger Discovery Book.  

4. Circus Circus Las Vegas
The circus is always in town, thanks to Circus Circus Las Vegas. It’s the world’s largest permanent circus, and puts on live acts on the Midway featuring flying trapeze artists, jugglers, tumblers, aerialists, tightrope walkers, and clowns. Over at the Adventuredome Theme Park, 4D adventures with Dora, Mumble, and SpongeBob share five acres with bumper cars, water rides, roller coasters, and more.

3. Bonnie Springs Ranch
With its famous old Nevada Western Town (a replica of an authentic 1880s mining town) and riding stables, Bonnie Springs Ranch is a treat for kids and parents alike. Explore the Old West soundstage, take a guided horseback ride through Red Rock Canyon (ponies for those under five), lunch in the authentic Saloon, and get up close with the native fauna in the petting zoo.

2. Shark Reef Aquarium at Mandalay Bay
With more than 2,000 animals living in 1.6 million gallons of water, Shark Reef is an anomaly in the desert.  Beautiful amphibians, reptiles, and sea creatures, including giant rays, sawfish, endangered green sea turtles, jellyfish, piranhas, and even a rare golden crocodile call this incredible refuge and educational facility home.  Oh, yeah—and sharks.  Lots and lots of sharks!

1. Springs Preserve
A Las Vegas original, Springs Preserve is a trip unto itself.  The Origen Museum currently features the exhibit Envenomators:  The Venomous Snakes of North America.  At the Nevada State Museum, you can get up-close with prehistoric skeletons and fossils. If you’d prefer to stay outdoors, trek the trails by foot or bicycle.  Afterward, at the Nature Exchange, young explorers can identify, learn about, and trade in the natural items they find on their explorations.
