We visited here on 7/31/24. We spent about 3 hours in the museum and could have spent a couple of more. The museum opens at 10 am and closes at 5 pm. It is small but does a great job covering Los Alamos Lab's WWII role and the development of the A bomb. There is also a great area that covers the work the lab is currently doing, which is mind blowing. There is parking near the entry and in back of the building. If you are in Los Alamos this museum is worth visiting.

Even after going to the larger Nuclear Science Museum in Albuquerque, we enjoyed this one more. It did a better job of explaining the timeline from nuclear physics discovery to dropping of atomic bombs in Japan. Start with the excellent movie! Explained how the different bombs worked and had to-scale replicas. The museum also did a great job of explaining how the area was transformed during bomb development and what Los Alamos National Laboratories does today.

This is a great museum! Interesting and detailed history of the Los Alamos, the Manhattan Project and the atomic bomb. Super nice staff...and it's all free. The museum actually has several exhibits about energy and what's going on at the lab these days, but we were only interested in the atomic bomb stuff...and that part was stupendous. Watch the film first, and then check out the history exhibit and the replicas of the atomic bombs. You can see all you need in about an hour.

I went here for the first time recently and enjoyed it. Although it may have a somewhat narrow appeal, to those interested in the history of developing the first atomic bombs and to later developments in this field, the museum's presentation is very well-done. Even though I had very limited interest in these topics before a friend encouraged me to visit the museum, I have to admit that the quality of the museum exhibits and short video made me want to learn more. So for those with any interest in the development of the atomic bomb at Los Alamos, and the contributions from other locations, this will be a very worthwhile visit.

Was here years ago, but remembered nothing. Great little museum (not for young children who cannot read well), some good videos about the bomb and how it was developed. Good intro to the area if you are short on time. No charge to enter. Worth a visit.

Very good science museum with lots to learn and understand. Well laid out and presented. Pretty thorough history of Manhattan Project and development of nuclear science, along with aftermath of WWII. Definitely recommended. Better for teens and adults, not so much for young kids.

Informative museum. We learned a lot about the Manhattan Project. There were also exhibits about the work currently being done at Los Alamos. A good place to stop for a change of pace after a visit to Bandelier. My teenage son liked it, but since many of the exhibits were text heavy, I am not sure it would be a hit with younger kids.
