At the Museum of Natural History, popular kid destinations include the O. Orkin Insect Zoo, Hall of Gems and Minerals, Discovery Room, and Dinosaur-Fossil Hall (closed until 2019). The largest (stuffed) African bush elephant in the world is located at the rotunda’s center. If your kids like spiders and insects, then check out the tarantula feedings at the Insect Zoo. The Discovery Center houses hands-on-activities and a state-of-the art Johnson IMAX Theater. Also visit the Live Butterfly Pavilion where you’ll commune with hundreds of beautiful butterfly and learn more about their life cycle. There is a small ticket fee associated with this exhibit. Be sure to enter through Constitution Avenue with strollers (there are ramps, automatic doors there). There is a cafeteria with decent food for weary musuem visitors. Metro: Blue and Orange lines to Smithsonian.
