Dive through clouds into an underwater river at 30 meters
Cenote Angelita is one of the most surreal diving experiences on Earth. At 30 meters, a hydrogen sulfide cloud creates the illusion of an underwater river, complete with fallen trees appearing to grow from the mist. A must-dive for advanced divers.
Angelita Diving
Total Depth
The cenote reaches 60 meters, with the "river" experience at 30 meters. A true deep dive.
Certification
Advanced Open Water required. Deep diving experience strongly recommended.
River Level
The famous hydrogen sulfide cloud creates the underwater river illusion at 30 meters.
The Underwater River
At 30 meters, a layer of hydrogen sulfide creates a thick, cloudy layer that looks exactly like a river flowing through the cenote. Fallen trees emerge from this mist, creating one of diving's most surreal and photographed scenes.
Scientific Wonder
The hydrogen sulfide layer forms where organic matter decomposes in the absence of oxygen. This creates the mystical white cloud that separates the fresh water above from denser saltwater below.
Visual Experience
Descending through the cloud is like diving through fog. Below, the water clears again, revealing ancient tree branches that appear to grow from the "river" - a truly otherworldly experience.
The Angelita Experience
Your dive begins with a descent through crystal-clear fresh water, surrounded by jungle vegetation above. The halocline at 15 meters creates the first visual effect as fresh and saltwater mix.
At 27 meters, you enter the hydrogen sulfide layer - visibility drops dramatically as you descend through the "cloud." Emerging below at 30+ meters, you find yourself hovering over what appears to be a mystical river landscape.
The ascent is equally spectacular, rising through the layers and emerging into the light-filled upper waters. It's an experience unlike any other dive in the world.
Before You Dive
Deep Dive Profile
This is a deep dive requiring proper planning and air management. We ensure all divers are comfortable with deep diving before this experience.
Hydrogen Sulfide
The H2S layer has a sulfur smell but is not harmful during a properly conducted dive. We minimize time in this layer while maximizing the experience.
Photography
Angelita is one of the most photographed cenotes in Mexico. Wide-angle lenses capture the scale of the underwater river phenomenon.
