Nevada State Highway 375, officially renamed Extraterrestrial Highway in 1996 for the many UFO sightings along this lonely stretch of road, stretches for 98 miles from US-93 in the southeast to US-6 in the northwest. This is definitely an off the beaten path road trip. The highway crosses three large high desert valleys in south central Nevada. You’ll see just a few ranches along the way, but you’ll be very close to the mysterious Area 51, a super-secret Air Force test facility. People have reported seeing many unidentified and strange objects, especially at night, near the base.
