The best part about visiting this museum is that you get to drive by and look at the NSA from a distance. If you are looking to visit a museum with some pizazz - try the spy museum in DC.

This is a great museum if you are interested in code-breaking. It is not a rip-off for profit trifle like the so-called "Spy Museum" in DC. This is built by, and run by, people with deep knowledge and interest in this topic and is not a money making tourist trap. Highly recommended.

This is a top museum. Not well known, but far surpasses any expectation. the tour guides are well informed and interesting. you can actually use a real Enigma machine from a WWII German Submarine to print your own codes. Its a little out of the way, but most GPS can lead you to the small access road to the left... More

Absolutely great museum! Like everyone else we were entranced by the opportunity to use an Enigma machine to decode a message....super cool. Wonderful time.

Where else (but the CIA gift store) can you buy an NSA golf ball? Where else can you touch an enigma machine and wonder about the fascinating stories of history's cryptographers and covert collectors? Easy on and off the Baltimore-Washington Parkway

We began by touring the museum on our own and then attended a docent led tour where we learned so many interesting "extra" facts. They have some very interesting items and provide lots of information about the pieces. They also have lots of available documentation that can add to the learning experience. Kids can do a fun scavenger hunt as... More

A very interesting look at cryptography by the USA from the Revolutionary War to current day (almost). Our docent (Jill) is a former NSA employee and really enjoyed telling the stories and answering questions (she could not discuss some issues). Teenagers through baby boomers will enjoy taking around 90 minutes for the tour. There is also a library and small... More

One of the best code breaking museums there is in the world. They have the only WWII Japanese purple machines in the world. Interactivity and kid friendly. Perfect for the technological minded and math majors of the world.

I visited with two grandsons recently and we had a wonderful time. They were intrigued by the Enigma machine and loved the chance to encipher a message using it. The displays about Revolutionary and Civil War codes and ciphers were really interesting. At various places, there are interactive games that enabled us to guess the codes Navajo code talkers used...
