Located in a limestone quarry on the southern coast of the Bukit Peninsula, the aircraft is about five minutes away from the stunning Pandawa Beach and just off the Raya Nusa Dua Selatan Highway.

So how did nobody notice the arrival of such a massive plane, right by a major road?

That remains a mystery, as does the question of why here, and not a designated plane graveyard?

The plane has no livery or identifiable marks. Some speculate that it was to be converted into a restaurant but the owner ran out of money and left it to rust away. But that’s as far as the rumours go.

Instead, it is becoming a popular tourist attraction, along with another “lost” 737 that sits about 8km north.

However, the plane is located on private property surrounded by a huge gate and what appears to be a security guard, so those wanting to get a look up close need to pay a fee for access. Even then, they are lucky to be allowed inside.

A Vice reporter who tried to scale the fence to sneak a look — unsuccessfully — wrote about how they saw it from a distance and could tell it was “creepy”, making them glad they couldn’t actually get inside.

Meanwhile, travel blogger Josh recorded the exciting moment he laid eyes on the plane in a YouTube video. He says he asked locals and scoured the internet but could find nothing about why the plane was there.

“I have no idea how they got this plane to just sit here, but it’s here,” Josh says, and then tries to get access but is denied.

“I have never drove (sic) this far not to get inside something.”

Another traveller, Duncan Lyster, also recorded his failed attempt to get up close to the aircraft.

“We just paid like 25 cents each to come up this little hill to take a nice photo,” Mr Lyster said. “I don’t think we’re going to be able to get down there cos there’s a security guard and fences all around but should be cool to take a look.”

And so the mystery remains.
