(And while in the area, you can pop over to Craters of the Moon National Monument and Preserve.)

I always liked the picture of the young pony-tailed girl looking at the site of the Trinity explosion

There is a newer site, The Atomic Archive, but IMHO it lacks the charm of the now-archived version. To be fair, it does cover a lot more stuff, offering history, documents, books, etc., in addition to tourism guides.
Well, "nothing" is quite the wrong word to use here... There is no international law preventing it, on some countries (including the US; for others, there is).
It does remind me that I'd like to go by the Trinity test site (I think one of the lesser known aspects of the development of the bomb is that the first ever nuclear detonation was actually carried out on US soil/sand), but it's only open twice per year.
These 2 movies would be "Oppenheimer" https://www.imdb.com/title/tt15398776/ and "Asteroid City" https://www.imdb.com/title/tt14230388/
AFAIK, only the first is directly about the Atomic Bomb.
Also Trinity is worth visiting, although both a pain to get to and only open 2 days a year.
I've had friends who rocked up for conferences who were turned away at the door because of state sanctions against them, and the presence of a swimming pool training reactor on campus. You sometimes need to be careful, depending on your national affiliations.
