The Extraterrestrial Highway
Nevada State Route 375 and the road west, from a mailbox that keeps getting destroyed to a boundary you cannot cross, ending in two ghost towns on the edge of Death Valley.

OddWay draws your route first, then plots every stop that falls inside the detour you're willing to make. No hunting through a list to work out what is actually on the way.
Loading the map…
Every one of the 6 places in the index. Plan a route and the map narrows to what's actually near it.
This is the emptiest route in the index, and the one that most rewards taking seriously. Long distances between fuel, effectively no phone signal, and two stops where the interesting thing is a boundary you are not allowed to cross.
The shape of it
Start at Hiko and walk the foundations of Logan City, a silver camp that lasted four years in the 1860s. Then south on SR-375 — signed as the Extraterrestrial Highway since 1996, which was a tourism board decision rather than anything stranger.
The Black Mailbox is next, and you should expect not to find a mailbox. The original belonged to a rancher named Steve Medlin, was removed years ago, and the replacements keep getting destroyed. The one standing in mid-2025 was gone by November. The spot is the attraction.
The north gate follows: a public dirt road meeting a fence, warning signs, and cameras on the hill. Stop at the signs. Beyond them is restricted military property, patrolled by armed contractors, and photography is prohibited. This is not a place to test anything.
Then west to the Alien Center at Amargosa Valley for fuel and food, which after a day on SR-375 you will need.
Ending in the ghost towns
Rhyolite went up in the Bullfrog gold rush and emptied almost as fast. The BLM manages it and you can walk freely among the ruins, including the bank and the bottle house.
Leadfield is the better story. The boom lasted under a year in 1926, driven by promotion rather than ore, and it collapsed when the ground turned out to be worthless. It sits on the one-way Titus Canyon Road — which is scheduled to close from October 2026 to September 2027 for repairs, so check before building a day around it.
Take this seriously
Fuel at every opportunity. Carry more water than you think. Tell somebody the route.
The distances here are not the distances you are used to, and a breakdown on SR-375 is a genuinely serious situation rather than an inconvenience.
The Route
Logan City
Hiko, Nevada
Founded after silver was found at Mount Irish in 1865, with a post office by 1867 and largely abandoned by 1869 once the shallow high-grade ore ran out. Only stone foundations remain in the Pahranagat district, on rough desert roads.
The Black Mailbox
Rachel, Nevada
The current roadside mailbox at Mail Box Road continues a long-running Area 51 pilgrimage tradition after earlier versions were removed or replaced.
Area 51 Back Gate
Rachel, Nevada
A public-road approach ends at the restricted Area 51 back-gate boundary; view only from the lawful public side and obey every sign, barrier, and instruction.
Area 51 Alien Center
Amargosa Valley, Nevada
A brightly themed alien travel stop near the Death Valley junction combines UFO souvenirs, oversized extraterrestrial imagery, and Highway 95 roadside kitsch.
Rhyolite Ghost Town
Rhyolite, Nevada
One of Nevada’s most substantial ghost towns preserves the skeletal remains of a once-booming Bullfrog mining city only a few miles from Death Valley.
Leadfield
Beatty, Nevada
The boom lasted under a year in 1926-27, after aggressive promotion pulled miners and investors into Titus Canyon and poor ore collapsed the whole thing. A few shacks, workings and ruins remain along the one-way Titus Canyon Road — which is scheduled to close from October 2026 to September 2027 for repairs.
