Have you ever been scuba diving in the Mexican cenotes before? If so, I’d love to know about your experience. What dive shop or liveaboard did you use? Which dive spots are the best and what are the conditions there regarding the visibility, water temperature, wildlife attractions, etc.?

Best Cenote Diving Mexico
Background – The Yucatan Peninsula is a low-lying flat area with a limestone foundation resulting from ancient coral reefs that became exposed when sea levels were lowered during the ice ages. Massive cave systems were formed when slightly acidic rainwater caused the dissolution of the porous limestone with impressive stalactites, stalagmites, and columns remaining in the hollowed-out sections. Sea levels subsequently rose to flood the caves. Today there are virtually no surface rivers or streams on the Yucatan but there are three substantial subterranean water systems running throughout these caves. The limestone in many places has collapsed from the surface in the form of sinkholes which are known as cenotes. Today estimates range to 30,000 for the number of exposed cenotes providing access to these underground cave and water systems.
Underwater World – For the purposes of scuba diving we can consider that cenote diving is cavern diving. Only a basic certification is all that is required to participate. You are diving in a cavern when there is natural light (in the daytime) that is always visible. You will never be more than 40 meters (130 feet) horizontally and vertically combined from the surface. It is true there are opportunities for deep penetration into small passageways far from the surface, but that is only for individuals with advanced technical training to attempt. Most of the sites have got the major pathways well marked with safety lines for guidance.
Cenotes are often set in a tropical jungle setting requiring a vehicle and sometimes a nature trek to get to them. The water typically has exceptional clarity and supports at least 15 species of freshwater fish including tetras, mollies, catfish, blind cavefish, and blind crayfish, as well, along with chara, a common species of algae in cenotes. In areas near the openings, there can also be fallen trees and other plant life from land that rest inside.
Haloclines are an interesting visual phenomenon to watch out for that occurs when higher density seawater that has penetrated from coastal waters below meets the freshwater on top of it creating a swirling blurry effect.
In addition to the fantastic natural formations like stalactites, etc., there is also evidence of ancient sacrificial and burial grounds to explore. Typically there are large chambers with magical vistas that are the delight of wide-angle photographers.
For your journey into the caverns and caves of the cenotes, you will need a good flashlight or two for safety and to fully explore the large chambers and nooks and crannies. Here is my review to introduce some top models:
Cavern Diver Training
For training in cavern diving, you could consider the PADI Specialty Course – Cavern Diver available from many area dive centers. If you are looking for advanced technical overhead environment training, there are also several shops on the Riviera Maya that offer it.

Seasons and Conditions – Diving is possible all year in the cenotes on the Yucatan. December through April is the busiest time. Early booking is advised. From May to September light is better making for better visibility and photography conditions.
- The air temperature average daily high range is 28-33°C (82-91°F).
- The water temperature in the cenotes can be cooler than in the nearby Caribbean with a range of 20-26°C (68-78°F). On average the temperature is 24-25°C (75-77°F). Check with your guide for what to expect on the day and select the appropriate thermal protection.
- The strongest rains come from June through October with 10-16 days of rain per month during that time frame. This is also the season when there is a possibility of hurricanes.
- Currents are minimal to non-existent in the cenotes.
- Visibility is excellent. Divers need to exercise caution not to stir up sand and silt to spoil it.
There are sites suitable for all levels of diver from shallow caverns to deep penetration through narrow passageways requiring advanced technical skills. From the primary locations of access in Playa del Carmen and Tulum, there are more than 75 dive shops, some associated with hotels, that offer a full range of diving coursework, equipment rental, and guiding in the cenotes. Some of the shops specialize in services provided but overall they can offer trips to the top cenotes in the region, local ocean dives, and sites along the Riviera Maya and around Cozumel.
There are not any liveaboard yachts cruising the Riviera Maya, however, there are several world-class dive safaris to relatively nearby Belize, Roatan, and the Caymans. Here are links to the vessels followed by my reviews of diving and liveaboards at Caribbean destinations including these three:
