IRL, the stateside nuke tests were done in White Sands, New Mexico.
All the initial Above Ground tests were done at White Sands. There was almost a 1,000 test blasts in Nevada, most of which were underground. The reason they were moved there is most of Northern and Western Nevada is Federal Government land, not like BLM land, but "keep your ass off because it's mine" land. It was real easy to keep people away from the test sites. There are also large No Fly zones that are not anywhere near the Nevada Test Site or Groom Lake because the military does training flights of current production craft.
I am not sure if I would want to see the Nevada Test Site as it is really just a big bombing range. Not everything tested here were Nukes, regular bombs too, along with vehicles and planes. Most of the blasts were done underground, so all one would see are large domes in the ground where the earth was pushed up. Also, while the entrance to one of the borders may only be 60 to 100 miles away, and there might be some administrative offices near the gate, all the real testing was done many dozens of miles farther in to the complex.
Area 51 would be more fun to poke around in as a dilapidated old complex.
