In 2011, the Air and Space Museum had more than 7 million visitors, making it the most popular museum in the country. It isn’t hard to assess its appeal—the place is home to the world’s largest collection of air and spacecraft, as well as interactive flight simulators, a planetarium, Imax movies, and more. Initially signed into law by President Truman as the National Air Museum in 1946, the museum was renamed the Air and Space Museum in 1966 by President Johnson.
The museum moved to its current home in a sleek marble-and-glass building on the National Mall in 1976, and promptly welcomed 5 million visitors in just six months. Just past the Mall entrance is the Milestones of Flight entry hall, which gives a nice visual history of aviation by displaying Charles Lindbergh’s Spirit of St. Louis, the Bell X-1 in which Chuck Yeager broke the sound barrier, and the North American X-15—the first aircraft to break Mach 4, 5, and 6—as well as the Apollo 11 command module Columbia. Don’t miss the Golden Age of Flight gallery, which includes Howard Hughes’s H-1 racer, or the Barron Hilton Pioneers of Flight wing on the second floor, which celebrates people who achieved significant “firsts” in flight.

Rivaling the Air and Space Museum in terms of popularity, the Natural History Museum is one of the oldest on the Mall, having sat in its current domed Beaux-Arts building since 1910. The museum owns more than 126 million items in upward of 1.5 million square feet of exhibits. It was originally founded in 1846, at the same time as the Smithsonian Institution; construction on the new building was halted in 1905 because Smithsonian leaders objected to the French-influenced design of the museum’s entrance, which was subsequently simplified.
The Constitution Avenue entrance leads to a lobby where an Easter Island statue stands guard; exhibitions include a 1.6-million-year-old Kenyan hand-ax and Northwest Coast totem poles. On the first floor, a 13-foot Fénykövi elephant from Angola sits under the central dome in the rotunda, while the adjacent Sant Ocean Hall is dominated by the model of a North Atlantic right whale. Upstairs on the second floor, the 45.52-carat Hope Diamond is the centerpiece of the Gems and Minerals gallery, and the Butterfly Pavilion allows visitors to walk through an indoor garden surrounded by hundreds of live butterflies and moths (tickets are $6). The nearby Insect Zoo features creepy crawlies, including live tarantulas, cockroaches, and bees. An Imax theater on the first floor shows nature movies on six-story-high screens.

Set on 163 acres in Northwest Washington, the National Zoo was founded in 1889 to inspire the “advancement of science, the instruction and recreation of the people.” Since the 1960s, the zoo has worked toward conserving and breeding endangered species; its 3,200-acre complex in Front Royal, Virginia, serves as the headquarters for the Smithsonian Conservation Biology Institute.
The zoo’s DC space is home to about 2,000 animals of 400 different species, the stars of which are undoubtedly the giant pandas, Mei Xiang and Tian Tian, who are on loan from China through 2015. The panda exhibit leads into the Asia Trail, which includes clouded leopards, red pandas, sloth bears, and fishing cats. The zoo’s Asian Elephants exhibit is currently undergoing expansion to provide the animals with a new home. Phase one of the Elephant Trails opened in 2010, with a new 5,700-square-foot barn, two outdoor yards, a pool, and geothermal wells buried underground to regulate temperature.
The park also includes a Reptile Discovery Center with turtles, snakes, alligators, Komodo dragons, and more; a Bird House; a Great Cats exhibit with Sumatran tigers and African lions; a Great Ape House; and several other exhibits. Don’t miss Amazonia, a 15,000-square-foot rainforest exhibit with a 55,000-gallon aquarium and more than 350 species of tropical plants.

One of the oldest botanic gardens in the country, this giant “national greenhouse” on the Mall was initially conceived in 1816, and opened to the public in 1850. Set on three acres, the gardens consist of three parts: a conservatory containing around more than 4,000 plants, the National Garden outside, and Bartholdi Park across the street. Built in 1933, the Conservatory features almost 30,000 square feet of space and includes an orchid court, a desert garden, a children’s garden with activities, and an oversize jungle area in the center with a viewing balcony from which to observe the tropical plants and vines.
The National Garden includes a rose garden and an amphitheater made from the marble steps of the Capitol’s old east portico, a butterfly garden, and a water garden dedicated to the First Ladies of the United States, while Bartholdi Park has a spectacular, recently restored fountain as its centerpiece.

Visitors can bike, walk, or drive through the National Arboretum’s 446 acres to see dogwood and magnolia collections, a bonsai and penjing museum, and a grove of state trees. As at the Botanic Garden, remnants of the Capitol’s old east portico can be found here; marble columns stand among a reflecting pool near the center of the grounds. The arboretum is especially well known for its magnificent collection of azaleas, which typically bloom between April and May. The collection was threatened by a lack of funding in 2010 but was saved by an anonymous donation of $1 million. The Perennial Collection includes flowering peonies, daylilies, daffodils, and more; the National Herb Garden is home to holly, juniper, pansies, and more than 100 varieties of roses.

Right next to the Capitol sits the largest library in the world, housing books, photographs, maps, and other items on more than 500 miles of bookshelves. The Library of Congress dates back to 1800, when President Adams signed a bill inaugurating Washington as the official seat of government and granting $5,000 to establish a library in the Capitol. After the building was burned down by British troops in 1814 and the books destroyed, Thomas Jefferson offered his own collection of tomes as a replacement.
The library itself now takes up three buildings in DC and the Packard Campus in Culpeper, Virginia, and has more than 151 million items in its collection, including 66.5 million books, 34.5 million manuscripts, and an extensive collection of music, photographs, and film.
The Jefferson Building has plenty to offer visitors, including free, docent-led one-hour walking tours five times a day. Inside, murals, statues, and mosaics adorn the walls and the ceiling of the dome—you can take a peek into the main reading room from a balcony on the third floor. On the second floor, “Thomas Jefferson’s Library” displays the 6,487 books on which the current library was founded. You can also see the Gutenberg Bible and 15 other early bibles in interactive form on the first floor in the Great Hall East. And if you want to access any of the library’s books, you can sign up for a research card if you have a photo ID.

This heart-rending museum explores the history of the Holocaust, from the beginning of the Nazi party through liberation, as well as the continuing occurrences of genocide in the modern world. Opened in 1993 by President Clinton, the museum was designed by Holocaust survivor and architect James Ingo Freed, incorporating different architectural traditions into a stark, evocative whole. The Hall of Remembrance serves as a tribute to the 11 million victims and survivors of the Holocaust; the permanent exhibition deals with the rise of Nazism, Kristallnacht, concentration camps, war crimes trials, and more.
The museum’s collection of artifacts includes a train car used to transport Jews, oral histories from survivors, diaries, toys, and photographs, as well as a deeply moving display of thousands of pairs of shoes. The museum is not recommended for children under the age of 11 due to its serious themes and subject matter.
