The Fatal Solo Dive of Playa del Carmen’s Young Diver in Sistema Dos Ojos

| Mexico, Playa del Carmen, Sistema Dos Ojos | Unknown (Young Male Diver) |
On the morning of 28 April 2015, a young man from Playa del Carmen, Quintana Roo, set out for what should have been a routine dive. He rented a single SCUBA tank filled with normoxic gas from his uncle at a dive shop in Tulum.
This diver held only an Open Water certification—he was not certified for cavern or cave diving. Still, he planned to explore the open water locations along the coastal region of the Sian Ka’an Biosphere Reserve.
At 8:00 AM, he arrived at the entrance to Dos Ojos Cenote Park, paying his entry fee at the security gate. The park staff did not check his diving certifications or inspect his diving gear. After parking his vehicle, he carried his open water equipment past a park employee—the last person to see him alive.
The Dive Begins
Equipped with only one SCUBA tank, an open water diving mask, and a basic diving suit, the young man descended into the water alone. Without the proper training or experience in cave diving, he ventured where many divers use specialized diving tanks, diving computers, and extra safety equipment to survive.
Solo diving in a cave system like Sistema Dos Ojos is dangerous. It requires maintaining constant orientation and monitoring air supply carefully. The young diver’s diving computer would have tracked his depth and time, but only if he knew how to use it properly.
What Went Wrong?
No official records describe exactly what happened beneath the water, but this tragic incident serves as a warning. Diving alone in an environment designed for cave divers without proper certifications or backup gear dramatically increases risks.
Dos Ojos is famous for its stunning underwater passages, but it is unforgiving to those unprepared. The diver’s lack of specialized diving tanks or redundant air supplies meant he had no safety margin if trouble arose.

A Deadly Mistake
Many experienced divers warn against solo diving in caves. Without a partner, problems like equipment failure, disorientation, or sudden medical issues can quickly become fatal.
The park’s failure to check certifications or equipment created a dangerous gap in safety. With only a single SCUBA tank and no backup, the young man faced a high-risk dive he was not trained for.
After entering the West Ojo section of the Sistema Sac Actun, the diver was using standard open-water SCUBA gear and carrying his GoPro® camera to capture the experience.
He found the “Cavern” traverse guideline leading to the East Ojo. Once submerged in the West Ojo cavern zone, the East Ojo entrance becomes clearly visible.
It’s believed that the diver made a risky visual jump from the West Ojo guideline to the East Ojo’s permanent traverse guideline. From there, he followed a parallel line that veered toward the Bat Cave entrance, still within the same cave system.
This secondary guideline leads toward the Green Room, a small cenote opening, and from the Green Room, it’s possible to continue on the traverse toward the East Ojo cenote exit.
There’s little doubt the victim had been in this area before, likely on prior guided tours, making this a familiar environment for him.
The Discovery
Around 8:45 AM the same day, a cave-certified dive instructor from the Akumal Dive Center led a cavern tour into the East Ojo. His plan was to guide his group toward the Green Room.
During the dive, he noticed a blinking LED light—common on GoPro® cameras when recording. Following the light, he found a body.
The diver was in full open-water SCUBA gear, pinned unnaturally against the cave ceiling, some distance away from the permanent American Caving Accidents guideline.
Moving the Body and Emergency Response
The instructor carefully moved the body back to the safer area of the Green Room cenote exit. Local authorities were alerted immediately, but sadly, attempts to revive the diver failed.
This tragic outcome underlines the dangers of diving beyond one’s certification and training, especially in complex cave systems like Dos Ojos.
The Mystery of the GoPro® Footage
It’s unclear what happened to the GoPro® video recovered from the diver’s camera. That footage might hold important clues about the moments leading up to the tragedy.
Sadly, without access to that video, many questions remain unanswered.
The Crucial Role of Training
Cave diving isn’t just about equipment — it demands specialized training, experience, and respect for the risks involved.
This young diver only held an Open Water certification, which does not prepare someone for the challenges and dangers of cave environments like Sistema Dos Ojos.
His lack of cave diving certification meant he wasn’t equipped—either mentally or physically—to handle the complex underwater passages.
