Diego Adame was 21-years-old when he first dived into the darkness of this hole. He recalls the moment where he said, “For a split second I thought of death and myself dying that day.” During his dive, he lost one of his flippers and then after few minutes almost ran out of breath. So how deep it is? It is believed that this hole is 13-storeys deep which ends when a very huge cave can be seen which is curved and is 40 meters deep.
