Diving the Pit Cenote
Most visitors to the Yucatan book cenote dives in the cities they are staying and the dive shops will arrange transportation and equipment rentals. Cenote diving is a popular activity and there are many dive shops to choose from. We dove with Scuba Playa and would rate them as average. Overall everything went well and equipment was in relatively good shape. The concierge at Elements Playa del Carmen recommended a few dive shops in town, we visited two to ask a few questions and check out their dive equipment.
The cheapest cenote diving package we’ve seen is $150 two tank cenote dive, click here. I wish I would have booked this online because no dive shop in Playa del Carmen had prices this low. Highly recommend booking online here in advance not only for the price but then you can pay by credit card in USD instead of taking out money to pay in pesos.
Independent diving at the pit cenote is possible. Most local dive shops have rental equipment and air to allow you to visit the many cenotes without hiring a guide/dive master. Park fee for diving the pit: 570MXP combined with a Dos Ojos dive

The main draw to the Pit Cenote is the beautiful light beams that light up this deep cavern dive. There’s also an eerie layer of hydrogen sulfide toward the bottom of the main cavern that makes for some interesting pictures. To get the most out of this dive you should be Advanced Open Water certified or higher. The max depth of the main cavern is 40 meters and the acid layer at around 27 meters.
Topography of the Pit Cenote
The Surface of the Pit Cenote
At the surface, there is a 10-meter oval-shaped opening that opens up to a much larger cylindrical cavern. At the surface, there is an overhang with some stalactites clinging to the ceiling.
At 10 meters the pit opens up to a further overhung cavern. At the edges of this overhang are rimmed with large stalactites.
The Light Beams of The Pit Cenote
The main draw for most divers are the dancing light beams that fill the cavern on sunny days. The narrow opening lets streaks of light into the pit cenote and the crystal clear waters let the light reach all the way to the bottom nearly 40 meters. It’s best to dive this site on a bright sunny day to have the best chance of seeing the light beams. Some of the best photos of the light beam will come from around 10-12 meters just above the fresh and salt water mixing layer.
The Fresh & Salt Water Mixing Layer – (Around 12 Meters)
Where the fresh and salt waters meet can very be poor visibility. At this level, the water appears blurry because of the way the light refracts in the two different waters. If you take photos in this layer they will appear out of focus. On our dive, the light beams were amazing while we were going through this layer, but all of our shots didn’t come out.
The Hydrogen Sulfide Layer of The Pit Cenote (Around 27 Meters)
Toward the bottom of El Pit Cenote, there is a cloudy layer that almost looks like you are diving through fog. This is a natural phenomenon is called the Halicon Layer and it’s made of hydrogen sulfide suspend in the water. This layer can generally be found around 27 meters and is around 2-4 meters thick. This layer sits on top of rocks fallen on the bottom of the main cavern and there are also eerie tree branches laying in the acid fog.The Rocky bottom of the Pit Cenote (25-40 meters)
