Dive Trip Report | October 25, 2026 | Nohoch Nah Chich & Cenote Angelita, Mexico
Some diving experiences are memorable because of the extraordinary places we explore. Others become unforgettable because of the people we share them with.
Yesterday was one of those special days when both came together.
Our adventure took us to two remarkable cenotes in the Riviera Maya: the beautifully decorated underwater passages of Nohoch Nah Chich and the mysterious depths of Cenote Angelita, south of Tulum.
Two completely different underwater environments, one incredible day of diving, and a wonderful reminder of why personalized dive guiding makes such a difference.
A Different Approach to Cenote Diving
Our guest was an Advanced Open Water diver with approximately 60 logged dives. Although she had previous diving experience, this would be her first time exploring the cenotes of the Yucatán Peninsula.
Before meeting, we had been communicating through WhatsApp, and she mentioned feeling a little uncomfortable about starting the day with a deep dive at Angelita.
Her concern was understandable.
Angelita is an extraordinary dive site, but its depth, reduced visibility, and mysterious hydrogen sulfide cloud can feel intimidating, particularly for someone unfamiliar with cenote diving.
Rather than pushing her into an environment where she might not feel comfortable, I suggested a different plan.
We would begin at Nohoch Nah Chich, a relatively shallow cavern dive reaching approximately 6 meters (20 feet).
This would give us time to become familiar with each other, review cavern diving procedures, evaluate buoyancy, and build confidence before deciding whether to continue to Angelita.
After all, diving should never be about rushing someone beyond their comfort level.
It should be about creating an enjoyable experience while respecting individual abilities and safety.
Arriving at Nohoch Nah Chich
We met near the Dos Ojos cenote area and continued toward Nohoch in separate vehicles.
Upon arrival, I noticed that my guest was still a little nervous. She was eager to put on her wetsuit and get into the water.
But there was no reason to rush.
We first completed the necessary paperwork and then sat down for a detailed briefing.
I began by explaining the fascinating geological history of the Yucatán Peninsula, including the asteroid impact approximately 66 million years ago and the geological processes that eventually created the region's extensive underground water systems.
For many visitors, cenotes are simply beautiful natural swimming holes.
However, beneath their surfaces lies a remarkable world shaped by geological processes over thousands and millions of years.
My guest was surprised by how much history and science were connected to the experience.
We then discussed the differences between open-water cenotes, cavern diving, and full cave diving.
I explained the limitations of recreational cavern diving, underwater communication, proper positioning, and the importance of following the guide.
She would be diving with a single tank, while I would use my sidemount configuration with two independent cylinders.
We also reviewed the importance of maintaining a single-file formation and following established cavern diving procedures.
As the briefing continued, I could see her becoming more relaxed.
Sometimes, simply taking the time to explain what will happen underwater makes an enormous difference.
Building Confidence Before Entering the Water
Once we were ready, I helped carry her equipment to the water.
Before beginning the dive, we performed a buoyancy and weight check.
Moving from saltwater diving to freshwater requires adjustments in weighting because freshwater is less dense.
Proper weighting is particularly important in cenotes, where excellent buoyancy control helps protect delicate geological formations.
With everything checked and our communication signals reviewed, we were finally ready to explore Nohoch.

Nohoch Nah Chich — An Underwater Cathedral
Dive profile: Approximately 50 minutes
Maximum depth: 6 meters / 20 feet
We entered the water at approximately 10:30 in the morning.
And something wonderful happened.
We had the entire cenote to ourselves.
No other scuba divers.
No snorkelers.
Just the two of us, surrounded by the extraordinary beauty of Nohoch Nah Chich.
As we entered the cavern passages, the visibility was exceptional.
Our dive lights revealed enormous white limestone columns, delicate stalactites hanging from the ceiling, and stalagmites rising from the cavern floor.
The formations seemed almost endless.
Because there were no other visitors disturbing the water or illuminating the passages, we could appreciate the galleries in their natural tranquility.
It felt like swimming through an enormous underwater cathedral.
During our approximately 50-minute dive, we explored both established routes within the recreational cavern area.
Heaven's Gate — A Magical Moment
Approximately 25 minutes into the dive, we reached one of the most beautiful sections of the system.
Puerta al Cielo — Heaven's Gate.
Here, natural sunlight enters through another cenote opening, creating magnificent turquoise reflections.
The light illuminated the surrounding limestone formations, revealing their delicate shapes and brilliant white surfaces.
We continued following the guideline through a slightly narrower passage, surrounded by spectacular geological decorations.
Everywhere we looked, the cavern seemed to reveal something new.
As we began our return, I occasionally turned around to check on my guest.
Her expression had completely changed.
The nervousness I noticed earlier was disappearing.
Now her eyes were wide with admiration.
She was calmly taking photographs with her GoPro and enjoying the experience.
For me, as a diving instructor, these moments are particularly rewarding.
When I see a guest becoming comfortable and confident underwater, I know we can both enjoy the dive while maintaining the necessary attention to safety.

Sunbeams at the Entrance of Nohoch
Near the end of our dive, at approximately 11:20 a.m., we approached the entrance area.
The sunlight had changed considerably since we entered.
Beautiful beams of light were now penetrating the water, creating spectacular patterns across the cavern.
The surface was completely calm.
There were still no other visitors.
For a few moments, everything seemed perfectly still.
I remember thinking how privileged we were to experience this beautiful place entirely on our own.
When we finally surfaced, I asked my guest what she thought.
Her reaction said everything.
She was amazed.
She had never imagined that cenote diving could be so beautiful.
And our adventure was only halfway through.
Surface Interval — From Nohoch to Angelita
After leaving the water, we took our time removing and organizing the equipment.
I helped carry her gear back to the vehicle, and we changed her scuba cylinder in preparation for our second dive.
We also stopped for some fresh fruit and drinking water.
A comfortable surface interval is an important part of planning repetitive dives, especially when the next immersion involves greater depth.
Our surface interval was approximately 1 hour and 20 minutes, including the preparations and the drive toward Angelita.
We traveled separately, with my guest following my vehicle.
After approximately 40 minutes of driving, we arrived at Cenote Angelita, located south of Tulum.
The atmosphere here was completely different.
Unlike the peaceful solitude of Nohoch, Angelita was busy.
There were approximately ten vehicles in the parking area, with both scuba diving groups and freedivers preparing for their activities.
Angelita is particularly popular among freedivers because of its remarkable depth.
After paying the entrance fees and the applicable GoPro camera fee, we approached the site map for another detailed briefing.
Cenote Angelita — Entering Another World
Dive profile: 38 minutes
Maximum depth reached: 35 meters / 115 feet
Angelita is one of the most unusual cenotes in the Riviera Maya.
Unlike the decorated cavern passages of Nohoch, Angelita is essentially a deep, open sinkhole.
Its most famous feature is a mysterious hydrogen sulfide cloud, generally encountered around 30 meters (98 feet) deep.
Above the cloud, submerged trees rise from a mound of collapsed limestone and sediment.
The scene resembles a mysterious underwater forest.
I explained our planned descent carefully.
We would initially follow the cenote wall, using it as a visual reference.
The upper section of Angelita often has reduced visibility and a greenish appearance.
At approximately 15 meters, the underwater landscape begins to reveal itself.
The submerged mound and its trees become visible below.
I told my guest that we would descend gradually, almost like an airplane approaching a mountain.
We would glide toward the upper section of the mound, stabilize our buoyancy around 24 meters, and evaluate how she felt before considering any further descent.
There was no pressure to go deeper.
We would make that decision together, underwater, based on her comfort and the conditions.
Flying Above the Underwater Mountain
Once underwater, we followed the plan.
We descended slowly alongside the wall until the mysterious landscape began appearing through the greenish water.
Then, suddenly, the underwater mountain emerged.
Branches and tree trunks rose from the sediment-covered mound.
Below them lay the famous hydrogen sulfide cloud.
We glided over the upper part of the formation, maintaining controlled buoyancy.
At approximately 24 meters, we paused to evaluate the situation.
My guest appeared comfortable.
We moved toward two recognizable trees near the cloud, which I use as visual references during the dive.
Facing each other, we exchanged the underwater OK signal.
I asked whether she felt ready to continue.
She confirmed that she did.
We began our descent toward the cloud.
Crossing the Hydrogen Sulfide Cloud
The experience of entering Angelita's hydrogen sulfide cloud is difficult to describe.
The water gradually becomes cloudy.
Visibility decreases dramatically.
The surrounding landscape disappears into a strange whitish-brown haze.
Our dive lights become essential visual references.
As we descended, we maintained close visual contact.
Then, as we passed through the cloud, my guest's eyes suddenly opened wide.
She was experiencing something completely unfamiliar.
For a moment, she reached for my hand.
I helped stabilize her, and we continued carefully toward the sediment-covered slope below.
At approximately 35 meters, we reached a suitable area to level off.
Here, the environment changes again.
Below the cloud lies a layer of saline water, separated from the freshwater above by differences in density.
The transition can also produce noticeable changes in buoyancy.
The hydrogen sulfide layer has a distinctive sulfurous character, adding another unusual sensory element to the experience.
We followed the slope of the submerged mound, with the darker drop-off extending toward the deeper sections of the cenote.
Angelita reaches approximately 60 meters in depth, but our planned dive remained considerably shallower.
Throughout this portion of the dive, I carefully monitored our depth, remaining gas, and no-decompression limits.
Although my guest had excellent air consumption, depth and decompression limits remained important considerations.
We spent only a short time at our maximum depth before beginning our ascent.
Emerging From the Cloud
We gradually ascended along the slope.
Thirty-five meters.
Thirty-two.
Thirty.
And once again, we entered the mysterious cloud.
For a few moments, everything around us became white.
Then the water began clearing.
The submerged trees slowly reappeared.
Branches emerged from the haze, creating an extraordinary landscape.
Some divers compare this scene to a Tim Burton movie.
And I understand why.
There is something wonderfully surreal about seeing those dark tree trunks rising from a mysterious underwater cloud.
It almost feels as though the Headless Horseman might appear between the branches.
Angelita has that unusual combination of mystery, beauty, and adventure.
It can be intimidating at first.
But it can also become one of the most fascinating dives of your life.

The Geological History Behind Angelita
Angelita is an example of a deep collapse sinkhole, known in geological terminology as a doline.
Over geological time, the collapse of the limestone ceiling created a deep opening.
The fallen rock and sediment accumulated below, forming what is known as a debris cone.
This is the submerged mound visible during the dive.
The trees and branches surrounding it contribute to Angelita's remarkable appearance.
The cenote is predominantly open to the surface, rather than being a conventional overhead cavern dive.
However, one small section of the dive includes a short cavern passage.
And that was our next destination.
The Trident Stalactite and a Hidden Cavern
As we continued our controlled, multilevel ascent, we passed through the submerged trees.
It is important to emphasize that these formations must be respected.
Divers should never touch, sit on, or damage the submerged trees.
Photographs are welcome, but conservation always comes first.
We gradually ascended through approximately 27, 24, and 21 meters before continuing toward the cenote wall at around 15 meters.
Here, I began searching for a distinctive natural landmark.
A remarkable stalactite shaped like a trident.
This unusual formation is one of my favorite reference points in Angelita.
Behind and below it lies a small cavern passage.
The passage follows a short U-shaped route, approximately 10 meters long.
It is relatively narrow, around 1.5 meters across in some sections, requiring careful fin control and appropriate cavern-diving procedures.
Unlike most of Angelita, this section has a genuine overhead environment.
Inside, there is also a curious feature.
A small collection of animal bones.
Their exact origin and identification have not been conclusively established.
One local interpretation suggests that they could be remnants of activity by ancient Maya inhabitants, possibly dating back several centuries, when the water level was lower.
However, this remains an interpretation rather than a confirmed archaeological conclusion.
I showed my guest the bones, and she took a photograph with her GoPro.
We then exited the passage and returned briefly to admire the unusual trident-shaped stalactite.
From there, we continued our ascent.
The Final Ascent and Safety Stop
At approximately 12 meters, we continued following the cenote wall.
We gradually ascended toward 10 meters, maintaining a controlled pace and using the wall as a visual reference.
Around the 35-minute mark, we approached the final portion of the dive.
We reached approximately 6 meters and completed our safety stop.
Nearby, we could see freedivers practicing along their descent lines.
Angelita is shared by scuba divers and freedivers, making awareness of other water users particularly important.
Scuba divers should maintain an appropriate distance from freediving lines and avoid interfering with freedivers during their descents and ascents.
After completing our safety stop, we slowly surfaced and approached the exit platform.
Our second dive was complete.
Thirty-eight minutes underwater, with a maximum depth of 35 meters.
And what an experience it had been.
From Nervousness to an Unforgettable Experience
Once we were safely out of the water, I asked my guest how she felt.
Her answer surprised me.
She had actually enjoyed Angelita even more than Nohoch.
I smiled because it reminded me of something another guest once told me.
Angelita can be a little like meeting a mysterious bad boy.
At first, he might intimidate you.
But somehow, you end up falling in love.
That is exactly how Angelita can feel.
A little intimidating.
Mysterious.
Exciting.
And ultimately unforgettable.
Of course, not every diver will react the same way.
That is why personalized dive planning, careful observation, and respecting individual comfort levels are so important.
The goal is never to convince someone to dive deeper than they feel ready for.
The goal is to create the conditions for a safe, comfortable, and memorable experience within their training and abilities.
For this particular guest, beginning with a shallow cavern dive at Nohoch helped her develop the confidence to enjoy a completely different underwater environment later that day.
A Beautiful Ending to Our Diving Day
After finishing the dive, we took our time dismantling and organizing our equipment.
There was no rush.
We changed into dry clothes and talked about the day's experiences.
My guest mentioned that she still had some free time and wanted to explore the Tulum area before leaving.
I suggested visiting Cenote Car Wash, another beautiful freshwater location nearby.
Eventually, it was time to say goodbye.
She thanked me for the experience and mentioned that she would love to return for more diving in the future.
She also said she would recommend our services.
For me, that was the perfect ending to a wonderful day.
We had started with a guest who felt uncertain about diving in cenotes.
We finished with someone who had discovered two extraordinary underwater environments and was already thinking about returning.
These are the moments that make my work as a diving instructor so rewarding.
Every diver is different.
Every dive is different.
And sometimes, the most important part of guiding someone underwater is simply knowing when to slow down, listen, and give them the confidence to enjoy the adventure.
