Inside US conspiracy trail dubbed Route 666 where you can hunt for Bigfoot and visit UFO ‘crash sites’

Speculation focuses on the existence of secret tunnels and secret societies.

There are even rumors it is the Illuminati headquarters with artwork @that depicts the end of the world", myluggae adds.

Some believe the underground tunnels which exist underneath the airport were built as bunkers for the world’s elite in preparation for an apocalypse.

Others have reportedly linked them to the North American Aerospace Defense Command (NORAD)"

HAARP, ALASKA

The High-frequency Active Auroral Research Program (HAARP) was commissioned by the US Air Force and Navy in 1990.

It is used to study "the properties and behavior of the ionosphere", according to its makers.

Nasa says he ionosphere "stretches roughly 50 to 400 miles above Earth's surface, right at the edge of space."

But its high powered technology has led to some questioning whether it can be used to change the weather.

Venezuelan leader Huge Chavez wrongly suggested in 2010 it had caused the Haiti earthquake.

NBC noted in 2014 that it had also been incorrectly blamed for "global warming to natural disasters to mysterious humming noises in the sky."

AREA 51, NEVADA

 Area 51 might be the United States' most famous military base.

The covert Air Force base, located in Lincoln County, Nevada, was opened during the Cold War in 1955 but its existence was only officially acknowledged by the CIA in August 2013.

Despite this, Area 51 has long been notorious, largely on account of its frequent association with alien mythology and UFO conspiracy theories.

What precisely goes on inside the base is kept extremely secret, but it's thought the US military uses the site to develop cutting-edge aircraft.

Members of the public are kept away from the compound by warning signs, electronic surveillance, and patrols of armed guards.

It is also illegal to fly over Area 51, although the site is now visible on satellite images. 

The secrecy surrounding the base has fanned the flames of the aforementioned conspiracies about aliens and UFOs.

One of the most famous is the claim that the site hosts an alien spacecraft and the bodies of its pilots after they crashed at Roswell, New Mexico, in 1947. 

Others claim to have seen UFOs above or near the site, while some say they have been abducted by aliens, and even experimented on, before being returned to Earth.

SKINWALKER RANCH, UTAH

Skinwalker Ranch is home to some of America's most spine-chilling mysteries including horrific cases of cattle mutilation, sightings of shape-shifting creatures and talk of a Native American curse.

Real estate entrepreneur Brandon Fugal purchased the isolated spread from aerospace billionaire Robert Bigelow in 2016, who had spent decades investigating mysteries there alongside the US government.

He has since set up his own full-scale scientific probe into the 500-acre property in Northern Utah - which has been dubbed the "eeriest place on Earth."

Dr Travis Taylor - who has worked for the US Dept. of Defense and NASA - has launched a full scale investigation into the mystery.

Previously the Sun Online was given access to clips of the show which reveals the probe into the ranch - which has attracted interest from top stars fascinated with the paranormal including Robbie Williams and rapper Post Malone

Mr Fugal said: “I bought the ranch as a sceptic.  I had never seen a UFO, a ghost, an orb, or anything of the sort in my life.

“Those first six months of owning it I really saw nothing myself that would lead me to believe that there was anything unusual."

That all changed when he and others witnessed what he believes was a flying saucer hovering above the hills surrounding the ranch.

"We saw what can only be described as an unidentified flying object, a craft a forty, fifty-foot-long silver disc hovering right above the mesa," he said.

"This wasn’t just a blinking light in the sky or something that was a little bit ambiguous.

"This was a solid object that appeared out of nowhere could move in the blink of an eye and over a twenty second period perform manoeuvres that I believe defy any propulsion physics we’re acquainted with.”

For centuries the "cursed" region surrounding the area has been awash with stories of supernatural and unexplained goings on.

The ranch - which is guarded 24/7 by an armed security team - itself takes its name from shape-shifting demons which the Navajo tribes believed once prowled the plains.

FLATHEAD LAKE, MONTANA

The first reported sighting of the Flathead Lake Monster came more than a century ago.

Nicknamed "Flessie" it as has been described as a large eel-shaped creature.

Believed to be 20 to 40 feet long, those who claim to have seen it say it has dark blue-black skin and black eyes.

But it is not all bad.

In fact, one youngster who fell into the lake claimed it had saved him.

He told his mom: “The Flathead monster lifted me up."

WINCHESTER MYSTERY HOUSE, CALIFORNIA

The Winchester mystery house is name after the family who occupied it in the 19th century.

They were direct descendants of those who created the Winchester rifle and the home is said to be haunted by those killed by the gun.

Original owner Sarah L. Winchester was told by a medium that spirits had cursed her after the death of baby and husband.

A medium told her that the victims killed by the Winchester rifles "were seeking revenge by taking the lives of her family", according to the national park service.

SIXTH FLOOR MUSEUM, TEXAS

The Sixth Floor Musuem in Texas is located at the spot President John F Kennedy was assassinated.

Kennedy, the 35th president of the United States, was fatally shot during a presidential motorcade in Dallas, Texas on November 22, 1963.

The alleged lone assassin Lee Harvey Oswald was arrested for the crime but killed by Jack Ruby two days later.

Kennedy's murder has sparked a number of conspiracy theories, with many believing more than one person fired at the president and there was a cover up.

Tourists can attempt to uncover the truth here.

SAFEGUARD COMPLEX, NORTH DAKOTA

The Safeguard Complex was built to launch missiles.

It is a military facility in North Dakota that was only operational for a day despite costing billions.

That came as a a result of a "fears of a nuclear arms race", according to myluggae.

They add: "The huge pyramid structure that still stands is believed by many to be an indication that the structure is for the Illuminati, and is either still used by them today or serves as a Doomsday bunker."

ROSWELL, NEW MEXICO

New Mexico is home to the infamous Roswell Incident, which involved the crash of a large weather balloon near a ranch that some claim was actually a flying saucer.

The conspiracy was born out of a press release sent out by the Roswell Army Air Field (RAAF) on July 8, 1947, which stated they had recovered a "flying disk" from the crash site.

The army quickly retracted the statement and instead said the crashed object was in fact a weather balloon.

The incident didn't make headlines again until the late 1970s, when a retired lieutenant colonel claimed the balloon account was part of a government cover-up.

Legions of conspiracy theories have followed in the decades since.

BAYOU CORNE SINKHOLE, LOUISIANA

The sinkhole appeared in 2012 as a result of a collapsed salt dome cavern.

It now stretches more than 35 acres and is still growing to this day, baffling geologists and becoming the focus of a number conspiracy theories.

Witnesses are said to have claimed to have seen ‘hell’ in the hole.
