Since its opening in 1894, the Field Museum in Chicago has expanded to house 40 million artifacts and specimens, allowing visitors to learn more about nature and how to help our planet thrive. This museum is most famous for SUE, the most complete fossil model of a T. rex to date. The museum isn’t exclusively about dinosaurs; in fact, it boasts a wide range of exhibits, from Audubon's Birds of America to a memorial honoring American Indians’ involvement in World War II.

The National September 11 Memorial & Museum is in remembrance of the deadliest terrorist attack in U.S. history. The beautifully constructed museum walks visitors through the harrowing timeline, separated into three categories — events of the day, events before 9/11 and events after 9/11. These segments provide insight into the historical context leading up to 9/11, in-depth details of the day and how the world looks now after the events that transpired.

Don’t forget to visit the outdoor Memorial Plaza where you can find the twin memorial pools surrounded by the names of the victims. Anyone who has visited this memorial and museum will vouch that it is both difficult to handle yet unforgettably moving.

A list of must-see U.S. museums would be incomplete without at least one Smithsonian museum. The National Museum of Natural History, located on the National Mall in Washington, D.C., is probably the most popular of the Smithsonian museum family. The Smithsonian has a collection of 145 million specimens and artifacts to help tell the tale of Earth’s history and how human interaction has altered it. Learn about the animals of today, like elephants, butterflies and narwhals, or take a journey back in time with various fossil displays, including “The Last American Dinosaurs.”

The entire family will learn something new during this trip and despite its popularity, museum admission is free.

The history of U.S. fought wars is the common theme in the museum, with World War II and the Vietnam War planes being some of the highlights. Try your hand at a flight simulator, catch a movie in the theater or see the famous Blue Angels practice overhead. You can easily spend a full day or two in this massive museum.

The National World War II Museum in New Orleans strives to provide visitors with a better sense of the lasting impacts of this devastating war, while inspiring future generations to learn from this monumental tragedy.

The Road to Tokyo in the Pacific Theater Galleries highlights Japan’s involvement in the war.

This museum gives visitors a better grasp on the massive impact WWII had on the world, but it also serves as a way to honor and respect those who lost their lives fighting.
