Explore Las Vegas

Las Vegas is more than just casinos—not that we'll fault you for sticking to the Strip. You can explore museums and nearby national parks and hiking opportunities in addition to the glamorous spas, shopping, shows, and, yes, gambling that you can find on the main drag of Las Vegas.

Red Rock National Conservation Area offers hikers beautiful vistas, although you might want to wait until the cooler temperatures of fall and winter to try it out. Another way to escape the desert heat is to drive about an hour up to Mount Charleston/Spring Mountain National Recreation Area, popular in both summer for less punishing heat and in winter for snow sports. Vegas has plenty of opportunities for outdoors enthusiasts to get out of the city and enjoy nature.

For families searching for educational things to do in Las Vegas, consider museums that range from traditional to wild. The Discover Children's Museum is ready to help run off little ones' excess energy, while the Neon Museum offers a great view of an American advertising tradition. For older kids and teens, Bodies: The Exhibition and the National Atomic Testing Museum are chances to discuss biology and history. And if you're leaving the kids at home, the Burlesque Hall of Fame, Mob Museum, and other similarly grown-up museums are waiting to detail Vegas's scintillating past and present.

While you're in Las Vegas be sure to take in the sights of the Strip. You can walk along the main drag, perhaps while sipping on a margarita, and admire the glitz and lights of Las Vegas's famed hotels, malls, and attractions. Madame Tussaud's Wax Museum is right in the heart of things and perfect for pictures and selfies with "celebrities." Don't forget to plan time for Vegas's famous shows. From traditional showgirl reviews and resident singers to Cirque du Soleil's stunning offerings, Las Vegas is chock full of entertainment just waiting for you to arrive.
