Where Is Area 51 in Nevada?
Area 51 is a highly classified United States Air Force facility inside the Nevada Test and Training Range, in the southern part of the state. It sits roughly 83 miles north-northwest of Las Vegas. The commonly cited coordinates for the base are about 37°14′N, 115°48′W, at an elevation of around 4,494 feet.
Officially, the site is not called Area 51 at all. Its formal name is Homey Airport, with the aviation identifiers KXTA (ICAO) and XTA (FAA). It is also called Groom Lake, after the salt flat that sits just north-northeast of its airfield. Administratively, it is a remote detachment of Edwards Air Force Base in California, falls under Air Force Materiel Command, and lists the Air Force Test Center’s Detachment 3 as its garrison.
The nearest town is Rachel, a small community in Lincoln County. Groom Lake lies about 25 miles south of it. For the broader history of how the base came to exist, our overview of what Area 51 in Nevada is covers the spy planes and myths in more depth. Here the focus is geography: the Area 51 locations that actually appear on a map.
The Key Area 51 Locations on the Map
Think of the region as a set of nested zones, from the runway outward to the public highway. Each has a name, and each tends to get muddled in retellings.
The base and the Groom box
The original base was a rectangle about 6 by 10 miles. It forms part of what is known as the “Groom box,” a larger rectangle of restricted airspace measuring roughly 23 by 25 miles. The special use airspace over the field carries the designation Restricted Area 4808 North, usually written R-4808N. In January 1962, as the A-12 spy plane program ramped up, the Federal Aviation Administration expanded that restricted airspace, and the lakebed became the center of a 600-square-mile addition.
Groom Lake Road and the checkpoint
The most important ground connection to the outside world runs northeast from the lake. Groom Lake Road is wide and well maintained, threading through a pass in the Jumbled Hills. It once served mines in the Groom basin and has been improved since they closed. The road winds past a security checkpoint, and the restricted zone extends farther east than many visitors expect. Once it leaves restricted land, the road drops onto the floor of the Tikaboo Valley, passes dirt turnoffs to a few small ranches, and meets State Route 375 south of Rachel.
Rachel and the Extraterrestrial Highway
State Route 375 carries the nickname “Extraterrestrial Highway,” and the stretch around Rachel has become a genuine tourist destination for people drawn by the base’s reputation. These are the most accessible Area 51 locations: public road, a small town, and a lot of empty desert sky.
The internal road network
On the other side, the base connects to the internal road system of the Nevada Test Site, with paved roads heading south to Mercury and west toward Yucca Flat. None of these are public routes.
| Location | What it is | Public access |
|---|---|---|
| Homey Airport (Groom Lake base) | Classified Air Force airfield and test facility | None |
| Groom Lake salt flat | Dry lakebed used for unpaved runways | None |
| Groom box / R-4808N | Restricted airspace around the base | Closed to civilian flights |
| Groom Lake Road | Main access road through the Jumbled Hills | Only the stretch outside the restricted area |
| Tikaboo Valley | Valley floor east of the restricted zone | Outside the boundary |
| Rachel, NV | Nearest town, tourist stop | Open |
| State Route 375 | The “Extraterrestrial Highway” | Open public highway |
Groom Lake and the Airport Called Homey
Groom Lake itself is a salt flat in the Groom Lake Valley portion of the Tonopah Basin. It sits about 4,409 feet above sea level and measures roughly 3¾ miles north to south and 3 miles east to west at its widest point.
That flat, hard surface is why the base exists. In 1955, when the CIA needed a hidden place to test the Lockheed U-2 under Project AQUATONE, project director Richard M. Bissell Jr. ruled out Edwards Air Force Base and Lockheed’s Palmdale facility because of the extreme secrecy the project demanded. Lockheed sent an inspection team, and designer Kelly Johnson later recalled that the dry lake looked like “another Edwards,” a natural landing field as smooth as a billiard table. The surrounding mountain ranges of the Emigrant Valley and the Nevada Test Site perimeter kept outsiders away.
Runways old and new
The site had aviation history before the CIA arrived. An airfield opened there in 1942 as Indian Springs Air Force Auxiliary Field, with two unpaved 5,000-foot runways. In May 1955 a survey team laid out a new 5,000-foot runway on the southwest corner of the lakebed, and within a few months the base had a paved strip, three hangars, a control tower and basic housing.
The A-12 OXCART program in the early 1960s transformed the layout. A contractor built a 10,000-foot runway diagonally across the southwest corner of the lakebed and marked a huge Archimedean spiral, about two miles across, on the dry lake so a pilot overrunning the runway could abort instead of plunging into sagebrush. Pilots called it “The Hook.” Unpaved crosswind strips were marked on the lakebed too.
Today the main paved runway, 14L/32R, is listed at nearly 12,000 feet of asphalt, with a shorter paved strip and four marked lakebed runways of 10,000 to roughly 11,400 feet. For a closer look at what fills the space around those runways, our piece on what is inside Area 51 walks through the hangars and buildings in the declassified record.
Before the planes: the mines
The name “Groom” predates the Cold War by nearly a century. Lead and silver were discovered in the southern Groom Range in 1864, and in the 1870s an English company, Groome Lead Mines Limited, financed the Conception Mines, giving the district its name. Mining continued until 1918, resumed after World War II and lasted into the early 1950s. The small mine in the basin was closed when security tightened for the OXCART program.
The Neighbors: Nevada Test Site, Yucca Flat and Yucca Mountain
One reason Area 51 locations are easy to confuse is that the base sits beside other famous government land. It shares a border with Yucca Flat, the site of 739 of the 928 nuclear tests conducted at the Nevada Test Site by the US Department of Energy. The Yucca Mountain nuclear waste repository lies southwest of Groom Lake.
When the CIA chose the site in 1955, it asked the Atomic Energy Commission to acquire the land, which was designated “Area 51” on the map, and add it to the Nevada Test Site. That administrative link explains why the base sits among numbered areas and why roads run straight from it into the test site’s interior, south to Mercury and west to Yucca Flat.
How Area 51 Locations Got Their Names
The base has collected more names than almost any airfield in the country, and each points to a different chapter.
- Area 51. The origin is genuinely unclear. One explanation ties it to an Atomic Energy Commission numbering grid, though Area 51 does not fit that system and sits next to Area 15. Another holds that 51 was picked because the commission was unlikely ever to use it. The name does appear in a CIA document from the Vietnam War era.
- Paradise Ranch, or “the Ranch.” Kelly Johnson coined it to coax workers into moving to what the CIA later described as a new facility in the middle of nowhere. It was shortened to “the Ranch.”
- Dreamland. This is the approach control call sign for the surrounding airspace, and the nickname stuck.
- Homey Airport and Groom Lake. The names the CIA itself used, and the formal aviation identity today.
- “An operating location near Groom Dry Lake.” The careful phrasing Air Force public relations has used.
For decades, officials would not confirm the place existed. That changed on June 25, 2013, when the CIA publicly acknowledged the base through records released under a Freedom of Information Act request filed in 2005. The declassified history describes its purpose during the U-2 and OXCART years. All research and activity there is classified at the Top Secret/Sensitive Compartmented Information level, and the base is widely believed to support experimental aircraft and weapons testing.
Can You Visit Area 51? What the Public Can Actually See
The short answer is no. The base, the lakebed and the land around them are restricted, and there are no tours. That also settles the common question of an age limit: the facility admits no visitors at any age. The useful question is which Area 51 locations are open, and the answer is mostly roads, a small town and long-distance views.
What is open
- State Route 375. A public highway through high desert, popular with travelers chasing the base’s mystique.
- Rachel. The nearest town and the hub of the region’s tourist trade.
- The Tikaboo Valley outside the boundary. The valley floor and the unrestricted end of Groom Lake Road lie beyond the restricted zone, though the dirt turnoffs there lead to private ranches.
- Distant peaks. The base has been photographed from distant Tikaboo Peak. Even that view is a long look across a valley, not a glimpse of anything up close.
What is not
Everything past the restricted boundary is off limits, including the stretch of Groom Lake Road beyond the security checkpoint. The restricted area extends well beyond the base itself, so the edge of that zone, not the airfield, is the line that matters. Crossing it means trespassing on a classified military installation.
Practical cautions
This is remote desert. Services are sparse, distances are long and summer heat is severe. Anyone driving the region should carry plenty of water, keep the tank topped up, stay on public roads, and treat every boundary sign as final. Remote summits demand real hiking experience and preparation; they are no casual detour.
Mistakes People Make When Mapping Area 51 Locations
Because the base was officially unacknowledged for so long, a lot of folk geography grew up around it. A few errors come up again and again.
- Placing it next to Las Vegas. The base is about 83 miles north-northwest of the city, a long drive into empty country, not a suburb on the edge of the Strip.
- Treating Rachel as the gate. Rachel is the nearest town, but Groom Lake sits about 25 miles to its south, behind mountains and a restricted zone.
- Confusing it with the nuclear test areas. The base borders Yucca Flat and connects to the Nevada Test Site road network, but the airfield and the bomb-test basins are different places with different histories.
- Assuming the base is the boundary. The restricted area around the airfield stretches farther east than the base, and the airspace above it, the Groom box, is larger still.
- Expecting an official “Area 51” sign on the map. Aviation charts and official references use Homey Airport, KXTA or Groom Lake. The famous name is the nickname, not the formal one.
Getting these details right matters for more than trivia. It separates the documented landscape from the imagined one, which is the first step in weighing any story told about the place.
Why the Geography Fuels the Legend
The physical setting of Area 51 locations does a lot of the storytelling work on its own. A hidden airfield on a lakebed, ringed by mountains, guarded by a checkpoint and capped by restricted airspace, practically invites speculation. Add decades of official silence and a call sign like Dreamland, and the base became a central piece of modern UFO folklore.
The documented record offers a grounded explanation for much of that mystique. The closed airspace above Groom Lake sat within the wider Nellis range airspace, and other pilots saw the A-12 20 to 30 times. Aircraft built to fly higher and faster than nearly anything else of their era, tested in secret over remote desert, are a strong ordinary candidate for at least some strange sightings in the region. Skeptics point to that as the core of the base’s reputation.
Others argue that the secrecy itself leaves room for stranger possibilities, and that a facility still classified at the highest levels cannot be fully accounted for by declassified history about the 1950s and 1960s. That debate runs through our look at the alien from Area 51 legend and the wider UFOs and UAP section, where UAP (unidentified anomalous phenomena) is the government’s current term for unexplained aerial sightings.
| Documented | Claimed or unproven |
|---|---|
| A classified Air Force airfield exists at Groom Lake | Recovered alien craft are stored there |
| Acquired by the CIA and Air Force in 1955 for U-2 testing | The base was chosen for contact with non-human visitors |
| Hosted the A-12 OXCART and D-21 drone programs | Strange lights over the region are extraterrestrial |
| Officially acknowledged by the CIA in 2013 | Hidden facilities match specific popular accounts |
What remains open is simple to state: what the base does today. Its present work is not public, and no amount of map reading will change that. What the map does settle is where the mystery lives: a dry lake in the Nevada desert, about 25 miles south of a small town on a lonely highway.

Questions and answers
Where is Area 51 in Nevada?
Area 51 sits in southern Nevada, inside the Nevada Test and Training Range, about 83 miles north-northwest of Las Vegas. Its airfield lies beside Groom Lake, a dry salt flat roughly 25 miles south of the small town of Rachel. The commonly cited coordinates for the base are about 37°14′N, 115°48′W. The nearest public road of note is State Route 375, nicknamed the Extraterrestrial Highway.
What air base is Area 51?
Area 51 is a classified US Air Force facility, officially called Homey Airport (ICAO code KXTA, FAA code XTA) or Groom Lake. It operates as a remote detachment administered by Edwards Air Force Base in California, under Air Force Materiel Command, with the Air Force Test Center's Detachment 3 listed as its garrison. The Air Force has described it as an operating location near Groom Dry Lake.
Can you visit Area 51?
No. The base and the land around it are restricted, and the public cannot enter or tour it. Visitors can drive State Route 375 and stop in Rachel, the nearest town, which has become a tourist stop for people drawn by the base's reputation. Anyone exploring the region should stay on public roads, respect every boundary sign, and carry water and fuel, since the desert there is remote.
Is there an age limit for Area 51?
The Nevada base has no visitor age limit because it admits no visitors at all; access is restricted to authorized personnel at any age. The question usually concerns unrelated businesses elsewhere that use the Area 51 name. Each of those sets its own rules, so the only reliable answer comes from the specific venue, not from anything connected to the Air Force facility.
Is there something in Area 51?
Yes, an active airfield and test facility. Declassified CIA history shows the site was set up in 1955 for U-2 spy plane testing and later hosted the A-12 OXCART and D-21 drone programs. Current operations are classified, but the base is widely thought to support experimental aircraft and weapons testing. Claims of alien craft or bodies stored there remain unproven folklore.
Why is it called Area 51?
The origin of the name is unclear. One explanation ties it to an Atomic Energy Commission numbering grid for the Nevada Test Site, though Area 51 does not fit that system and sits next to Area 15. Another holds that 51 was chosen because the commission was unlikely to use it. Officially the site is Homey Airport or Groom Lake, with nicknames like Paradise Ranch and Dreamland.
