A SINISTER “cave of death” in Costa Rica kills any living creature that dares to step inside.
The deadly cave is located on the edge of the Poas Volcano in Costa Rica and is strictly prohibited from entering.

Cueva de la Muerte translated to Cave of Death from Spanish is a tourist attraction that doesn’t actually let anyone visit inside.
The terrifying placard outside of it warns: “Danger, no trespassing beyond this point.”
And the images of skulls are just a sign hinting to what could happen to trespassers.
But poor animals that can’t read the warning die instantly when they enter the cavity.
The reason behind eerie phenomenon in the Cave of Death is the high levels of CO2.
The cave itself emits nearly 100 per cent carbon dioxide, a colourless, odourless and tasteless gas that is highly toxic and can be fatal.
Guy van Rentergem and his team found out that the deadly pothole produces 30 kilograms of carbon dioxide per one hour.
Any breathing being that steps inside it dies almost instantly due to CO2 poisoning and lack of oxygen.
This strange occurrence is the result of a gas leak which comes to the surface through cracks in the earth‘s crust called “San Miguel Fault”.
Carbon dioxide is heavier than air, making it roll out mostly along the floor.
The spillover of the gas pools up at the entrance and leaks over to the ground outside.
The cave itself is tiny and is more of a hole in the ground, extending ten feet into the hillside.
It ends at a crack too small for anyone but insects and tiny animals to enter.
Most common animals that end up in the oxygen-free zone and face an imminent death are rats, snakes and small birds.
The sinister cave is located on the territory of the hot springs resort.
It was discovered when the complex was being built, thanks to a worker who got close to the entrance to clean the area and soon felt sick.
The resort offers a demonstration to curious visitors of the effect caused by carbon monoxide in the cave of death.
They lit up a torch and show how the fire quickly extinguishes due to the lack of oxygen necessary for the combustion process.
Similarly, a horrifying cave was found in Saudi Arabia where a mountain of human bones was discovered in a large underground network of tunnels.
Scientists are also unravelling the mystery behind yet another deadly cave that the ancient Romans believed was the gateway to hell.
And in Mexico, the crystal cave 1,000 feet below Earth’s surface kills visitors in minutes.
