It's one third of the Manhattan Project National Historic Park, a few hours southeast of Seattle, with the other portions in New Mexico and Tennessee. I haven't been able to see the other portions, but walking into the main chamber of the B Reactor and looking up at it was an inspiring experience.
I've always considered myself fortunate for the various professional opportunities for hacker tourism that have come my way.
Tours never would have occurred to me. People should never forget what goes on there, I'll trust that the people in charge are good at risk management.
I was exploring California's wonderful nature on vacation and passed an interesting looking site that looked like a military/scientific installation. Because I am naive, I drove up to the base (Vandenberg afair) to ask for a tour. The local security personnel gave me a very bewildered look all while not taking their hands off their massive handguns. After checking my ID, another friendly soldier with an assault rifle made sure I find my way out the gate. Which is to say: I appreciate every opportunity to explore professionally as well. It is surprisingly hard to see what's going on in a lot of places otherwise.
I drove by this site many times in the 80s. Once, I ripped a metal sign off the fence next to the highway because it looked so cool to a teenager: DANGER BOMBING AND ARTILLERY RANGE in white red and black colors. It hung in my teenage bedroom for many years.
If this sort of thing interests you, another interesting tour is the Hanford Site B Reactor tour: https://www.nps.gov/thingstodo/hanford-attend-a-b-reactor-to...
