Area 51 is located within the Nevada Test and Training Range complex (NTTR) in southern Nevada, about 85 miles north-west of Las Vegas. It is hidden in the mountains around Groom Lake, one of many dry lake beds in the area, near the "Extraterrestrial Highway" 375 and the town of Rachel, NV.
The location of the base, in a valley surrounded by mountain ranges that are off-limits to the public, makes it almost impossible to see from public land. This of course creates an ideal setting for all sorts of top secret activities, such as Black Projects test and development.
