The museum is the only one of its kind in the country and houses hundreds of gadgets, weapons, vehicles, and devices that have been used for espionage throughout history.
You can also learn about famous (and little-known) spies throughout history.
Although most museums in Washington, D.C., are free, this one has an entrance fee of $13 for adults and $10 for children over 5 years of age.
To control crowding, tickets are assigned an entry time. Get in line early to purchase your tickets and plan the rest of your day according to your assigned time. These exhibits can be very crowded, even with the assigned entry times, so if you are a spy buff and like to read and experience all of the exhibits, plan to spend a minimum of 3 hours exploring the museum.
I would not recommend the museum for young children, as most exhibits require a lot of reading and there are few interactive exhibits. The museum store on the lower level is another matter. Children (and some adults) usually find it more interesting than the museum itself, and entry is free.
Additional facilities include a museum store and two restaurants: Zola and Spy City Cafe. Zola is an upscale restaurant (which requires reservations) that has a great martini bar and wide selection of champagnes. Spy City Café is a casual place to grab a quick sandwich or snack.
