Extraterrestrial Highway, United States
The Extraterrestrial Highway (Nevada State Route 375) runs 98 miles through the Nevada desert between Crystal Springs (at US-93) and Warm Springs (at US-6), skirting the northern boundary of the Nevada Test and Training Range — home to the classified Area 51 facility. Officially designated in 1996 after decades of UFO sighting reports, the road passes through one of the emptiest landscapes in the Lower 48. Rachel (population approximately 50), at mile marker 29, is the only settlement — home to the Little A'Le'Inn, a UFO-themed restaurant and motel. The Black Mailbox (now white, at the junction of Route 375 and Groom Lake Road near mile marker 29.5) is where UFO watchers gather at night to scan the sky above Groom Lake. The surrounding Tikaboo Valley offers views of the Pahranagat Range and Joshua tree forests. The restricted Area 51 perimeter — marked by warning signs and motion sensors — is visible down Groom Lake Road but entering is illegal.

Drive east to west (Crystal Springs to Warm Springs) to end with sunset over the basin-and-range landscape. The 98-mile drive takes about 90 minutes. There is no gas between Crystal Springs and Warm Springs — fill up at either end. Cell service does not exist along the highway. Bring water, food, and a spare tire. Do not turn down Groom Lake Road past the warning signs — trespassing on the military reservation is a federal offense.
Year-round, but spring (March-May) and fall (September-November) avoid summer heat exceeding 110°F. New moon nights offer extraordinary stargazing. Winter is cold but clear. The Little A'Le'Inn is open year-round but confirm hours before driving.
