A small cave in Venecia, Costa Rica has earned a reputation for killing anyone who dares enter it

The 6-foot-deep and 10-foot-long cave, that is barely large enough for a human to fit inside, is known as Cueva De La Muerte, or the ''cave of death''

A sign outside the cave reads: "Danger, no trespassing beyond this point''

It is believed that 30 kgs of Carbon dioxide is being emitted every hour from this small cave

Levels of the gas inside the cave are so high that it can cause unconsciousness almost instantly, followed by cessation of breathing

Luckily, humans are generally safe because it's too small to fit into

However, snakes, birds, rodents and other small creatures who enter the cave in search of food quickly die in a few seconds

Tour guides carefully approach the cave and perform demonstrations with fire torches

Fire needs oxygen to burn and the lack of oxygen extinguishes the blaze in a split second

Despite its dangers, tourists have been flocking to the site to take selfies and to get as close to it as they can
