I went in the spring and I really enjoyed it, although it was pretty cold and windy. The scenery around there is pretty striking and they do a good job of preserving some of the history of the area, including ground zero itself and the ranch house where the bomb was assembled. A couple things to mention. First, is try to get there early. I got there before it opened and had about a 30 minute wait until it opened but then not much of a wait to get in (although there was a line when I got there). That will let you get in before it gets too crowded. Also, if it is crowded you might want to take the bus to the ranch house early so you dont have to wait.

There are more there of ground zero, a the ranch, a pueblo 50 or so miles north of there and Pterogylph National Monument in ABQ.

One other suggestion, after you visit the site stop at the Owl Cafe near the entrance to the interstate for a green chili cheeseburger. I didnt care much for the branch in ABQ, but the one near White Sands is great.
