The top-secret Area 51 government base is near SR 375, and many travelers have reported UFO observations and other strange alien activity along this road. Such stories prompted the state to officially designate the route as the Extraterrestrial Highway in 1996. The small town of Rachel, located near the midpoint of the highway, caters to tourists, geocachers, and UFO seekers with alien-themed businesses. Although the area receives some tourism due to alleged extraterrestrial activity, SR 375 remains a lightly traveled route.
