Fodor's Expert Review Smithsonian National Museum of Natural History

One of the world's great natural history museums offers 20 exhibition halls—including a fully renovated Dinosaur and Fossil Hall, filled with not only fossils, but also glittering gems, creepy-crawly insects, and other natural wonders. There are more than 145 million specimens in the collection. Marvel at the enormous African bush elephant, which greets you in the rotunda, and learn about elephant behavior and conservation efforts. Discover Q?rius, a state-of-the-art discovery space for all ages featuring 6,000 objects, on-site experts, and an array of digital tools that focus on the natural world. Walk among hundreds of live butterflies in the Butterfly Pavilion ($8 adults, $7 children/seniors). Check out giant millipedes and furry tarantulas in the O. Orkin Insect Zoo (don't miss the daily live tarantula feedings). See perfectly preserved giant squids, a jaw-dropping replica of a whale, and the ecosystem of a living coral reef in the Sant Ocean Hall. Watch as paleobiologists study some of the museum's collection of 46 million fossils, which includes the nation's T. rex found in Montana in 1988.
