Cave diving is one of the deadliest hobbies in the world, something Axel Willems knows all too well. He spends his free hours diving in dangerous spots and filming the action. The only things keeping him alive are the two oxygen tanks he drags behind him on the cave floors.
Willems often visits places where the dying words of victims can be found scratched into cave walls. What he does inside one of these caves will terrify you.

This certainly wasn’t for the faint of heart. Seeing him dive into this silent graveyard left me with chills I don’t know how to get rid of.
