Area 51 is associated with Groom Lake in southern Nevada, north of Las Vegas, inside the Nevada Test and Training Range. The public cannot visit the installation. Declassified records document secret aircraft testing and pilot training there, starting with the U-2 and later including the A-12 OXCART. What is happening at the site today is still classified, and no public source reviewed here establishes it.
Where Area 51 is
Groom Lake is a dry lakebed in the Nevada desert, north of Las Vegas. The restricted site lies within the Nevada Test and Training Range. Travel Nevada places the base there and states that it is not a tourist attraction and cannot be visited.

“Area 51” is an unofficial name. The William J. Clinton Presidential Library and Museum’s finding aid for its Area 51 file (catalogue entry “(2006-0527-F) Area 51,” a National Archives and Records Administration record) describes it as an unofficial title often referring to an area in southern Nevada that contains U.S. Air Force facilities. The same finding aid states: “The USAF does not recognize owning or operating any facility regarded as ‘Area 51.'” It also says the Air Force recognizes operations in the Nellis Range Complex, which includes an operating location near Groom Lake. Readers searching for a single named facility will therefore find that the official record uses different terms.
Getting near the site
- No public access to the base. Travel Nevada says the installation is inaccessible and not open to tourists.
- Rachel, Nevada. The small town lies on the Extraterrestrial Highway and draws visitors as a roadside destination. It is not a gateway to the base, and nothing in the state’s material offers a tour or viewing point.
- No inside access. Nothing in the public record supports claims of tours, guided visits, or inside knowledge of current operations.
What the declassified record documents
Why Groom Lake: the U-2
The CIA’s historical account says the remote Groom Lake site was selected so the U-2 could be tested safely and in secret. The account describes early U-2 testing there. The National Security Archive, in its 2013 compilation of declassified documents, quotes a judgment that the site “would make an ideal site for testing the U-2 and training its pilots.” The Archive attributes that statement to the four officials who inspected the location, and it should be read with that context.
#1 Best Overall
The A-12 OXCART
The CIA’s account places the first A-12 OXCART flight test at Groom Lake on April 25, 1962. The OXCART was a successor high-altitude reconnaissance aircraft, and the CIA’s chronology links the site to its early flight testing. The record shows the base hosted this program during its development, not what it does today.
Stealth, radar, and Soviet MiGs
The National Security Archive’s compilation says Area 51 later played a role in U.S. Air Force stealth programs and hosted Soviet MiG aircraft that were obtained secretly. The documents detail radar testing and aircraft programs including the U-2, the OXCART, and the F-117. These records establish a historical role in sensitive aviation and defense testing. They do not establish a current list of programs.
Rank #2
Why UFO stories attached to the site
The CIA’s 2022 explainer rejects the popular claim that aliens or flying saucers are stored at the facility. It attributes many historical UFO reports to secret test flights and gives this figure: “U-2 and later OXCART flights accounted for more than one-half of all UFO reports during the late 1950s and 1960s.” The CIA attributes the share to those flights, and the page does not give an underlying count of reports, so the figure should be quoted with that attribution and no further precision.
Travel Nevada states that there have been no confirmed sightings of flying saucers or alien lifeforms at Area 51. The reviewed public sources therefore do not verify alien claims. That is different from proving that nothing unusual is classified, and readers should treat the two questions separately.

What is still classified
The Clinton finding aid states that much about activities at the Groom Lake operating location remains classified. This is the most current institutional statement in the public material reviewed. It means that the historical record above is reliable as far as it goes, while present-day projects are not publicly documented. Any claim about current testing is an inference, and a specific active project should not be presented as fact without a current authoritative source.
