Beyond the debaucherous nightlife and never-ending stimulation of the city, Las Vegas museums offer opportunities for regrowing some lost brain cells or, at the very least, spending some quality time with Halle Berry or Lady Gaga. Located inside The Venetian, Madame Tussauds wax museum invites visitors to gawk at uncanny sculptures of celebrities and sports icons alike. For a more traditional museum experience, head north of the Strip to the Las Vegas Natural History Museum, chock-full of Egyptian artifacts and lifelike wildlife replicas, including a 35-foot T-rex that actually roars. Fans of interactive exhibits, meanwhile, should visit the National Atomic Testing Museum, located just off the Strip, to experience a simulated atomic blast. Spooky.
