The National Atomic Testing Museum

Check for deals starting at $15

Equal parts science exhibit and history museum (with a dusting of extraterrestrials), this Smithsonian Institution affiliate pulls back the curtain on our country's nuclear-weapons-testing program. Along with learning the history of the atomic bomb, you'll pick up pointers on surviving a nuclear blast, and you'll actually get to weather the aftershocks during a simulated blast in the Ground Zero Theatre.

Las Vegas ATV Tours

Check for deals starting at $129

Take a break from the Strip by getting off-road with a wild ATV tour from Las Vegas ATV Tours. You'll get picked up right from your hotel and whisked away to the Nellis Dunes, which are sure to feel like an alien world compared to the neon lights of Sin City. First-timers will get some instruction from the talented guides before hitting the dusty trails for one-of-a-kind views of the city and surrounding mountains in the distance.

Gun Garage

Check for deals starting at $77

At this unique shooting range, it's not how well you shoot, but what you get to shoot that makes the biggest impression. In addition to all the standards, you can purchase packages that will allow you fire off everything from an old-school tommy gun to modern AK-47s. They even have rarer offerings, like the Browning machine gun, which was originally used throughout WWII. Don't worry if you're not an experienced sportsman, though, because an NRA-certified professional is on hand to provide detailed instruction, and safety gear is worn by all participants at all times.

The Pinball Hall of Fame

Beeps, bloops, and rattling clangs fill the air of every casino in Vegas. But inside the 10,000-square-foot Pinball Hall of Fame—one of the true Las Vegas hidden gems —those sounds echo from more than 150 pinball machines, all curated and lovingly restored by owner Tim Arnold. The history is palpable, as some of these machines date back to the '40s. And unlike at most Halls of Fame and museums, visitors are encouraged by Tim to touch (and play!) every single machine in his collection, which includes over 50 classic arcade games as well.
