Cozumel offers an exceptional variety of diving possibilities. With its extraordinary visibility, wealth of marine life, impressive reef formations and underwater landscapes the reefs of Cozumel are one of the most beautiful diving paradises of the world.

For experienced divers the cenotes located on the mainland, offer cave dives of the special kind. Hundreds of kilometres of well known and unknown cave systems inviting to be explored.

During the dive trips Aquamarinas provides you with cold softdrinks, lunch and fruits.

The boats are equipped with oxygen, first aid kit, fire extinguishers, life jackets, cellular phone, GPS, radiotelephone and especially with an experienced crew.

Neseccary dive qualification: For the boat dives at least PADI-OWD or Level I of another dive organisation; beginners and non certified divers can only carry out dives from the shore.

Necessary dive equipment: You need fins, mask, snorkel, bouancy control vest, regulator with octopus, inflator and manometer, diving suit, depth gauge and dive watch or computer. Gloves and diving knifes are forbidden in the marine park (except during dives at the wreck). A diving health certificate, not older then one year, is welcome. We recommend a diving insurance. Please bring your logbook and your brevet. The water temperature varies between 26 °C (79 °F) (winter) and 31 °C (88 °F) (summer), therefore we recommend a long 3mm diving suit. For divers who get cold quickly we recommend a 5mm diving suit for the winter and for the diving in the cenotes.

As a special service Aquamarinas takes on the daily transportation and the daily cleaning of your diving-equipment. Please take care of your personal things ( sun blocker, t-shirts, cameras ….) and of your valuables.

Unfortunately we cannot offer you the transportation to the boat, because the transportation of private persons and tourists is forbidden by the taxi association. The keeping of this rule is strictly controlled and contrevention highly punished. Therefore you are also not able to travel over the island by hitchhiking.

If you like, we can store your diving bags in the dive centre. Also on the last day of diving we can wash and dry your equipment, if you want. Then you can pick it up at the dive centre on the evening before or on the day of your departure.

Non-divers: We also greet non-diver aboard of our boats, if the boat is not fully occupied (see prices on the rate link).

We use aluminium tanks without reserve with 12 liters of filling. These are fitted out with yoke valves. Therefore, by DIN connections you need an adapter (it is placed at disposal, if necessary, by Aquamarinas). You need 3 kgs (6 lbs) of lead more than while diving with steel tanks. Using of a 3-mm suit it’s recomended that you carry 10% of the body weight in lead.

The required diving equipment can be lent from Aquamarinas.

Security: Our diving centre is attached to a hyperbaric chamber with qualified diving doctors on the island. You can visit the hyperbaric chamber at any time. Doctors specialised in hyperbaric medicine are constantly present there. English is spoken.

Night-diving: We offer night dives (minimum of at least 4 divers).

Reef Wreck Cenotes Training

Almost all dives at Cozumel are drift-dives with currents which are that change according to the diving site and season more or less strongly and can also change during the dive.
The boat follows the divers, so that one can drift with the current.

Shortly before the end of the dive a safety buoy is set and a safety stop on 5 ms is executed. 2 dives per trip are done between which a surface intervall of 90 minutes is made. During this time the divers are provided with snacks, fresh fruits etc that is contained in the diving price. The departure takes place between 09:00 and 10:00 o'clock in the harbour Caleta or at 09:00 at the pier in San Miguel and according to the distance to the diving site and the boat we arrive back between 14:00 and 16:00. The guests must make their own arrangements to come to the harbour at Caleta, because we may not carry persons on account of the taxi driver's guild. This is controlled regularly by the police.

Protection of the reefs: the reefs before Cozumel lie in the Nationally Nautical park. The fishing, hunting, collecting and use of gloves or knives are forbidden. To avoid losses to the underwater world, a good buoncy is expected from the divers (this is particularly expected of divers with video-equipment or photo-equipment). We ask not to disturb the fish and turtles.
Also, please, avoid the use of none biologically degradable sun protective agents. Aquamarinas thanks for your understanding and your co-operation for the preservation of the reefs. The entry into the Nationally Naval Parc costs 20 pesos per person and day (included in the prices). This money is applied for the protection of the reefs and its monitoring.

Dive Sites


One of the most northern dive spots and on account of the current not possible to dive there the whole year. There are no big coral formations, but the reef is densly covered with sponges and horn corals. In October and November one has the best chances to see big groups of eagle rays there. The diving area is, on account of the currents, reserved only for the experienced divers.


Beyond the naval protected area, this convenient diving spot is often choosen as the second divesite after a dive at barracuda. The partly extreme strong currents carries the diver about a colourful carpet of finger corals, sponges and algae.
The dive starts close to the coast in a depth of 10 to 13 ms and leads along beautiful obliquely dropping reef walls till one reaches with a depth of approx. 24 ms (79 ft) - according to air consumption - the dropoff of the barracuda reef. Good chances of seeing eagle rays.


Conveniently near of the harbour of Caleta, rich in animal and plant life. The diving area lies at a depth of approx. 14 ms (46 ft) and divides itself into three areas which are separated laterally by shifted sandy sections from each other. It is not a wall, and to both sides of the reefs there are sandy areas. Currents are often variable. One finds lobsters, king crabs, morays, big snappers and a lot more. Now and again eagle rays come to visit this reef.
It is the preferred diving place for night dives during which many king crabs and turquoise-coloured Caribbean octopusses can be seen.

The Cenotes were created by an elevation of the earth's crust or a lowering of the sea level that created the limestone caves which are flooded again today and belong to one of the most interesting diving attractions in the world. We use a complete set of safety equipment for the cave dives (double tanks., lines, two regulators, 3 lamps ...).

Within the framework of these dives every diver not trained for cave diving will stay in the area of the entrance of the cenotes and must constantly be in daylight. The cave dives are under the direct supervision of specially trained instructors.

Prerequisites: OWD-brevet or equivalent education level; a basic brevet can be sufficient if the diver is experienced. Good buoancy is required.

Organisation:You leave at 8.00 o'clock by boat from Cozumel to Playa del Carmen. The further transportation takes place by minibus or passenger car. Once you have arrived in the jungle, your equipment is made ready and it’s off into the underground world.

Dive: The water of the Cenotes is cooler than the sea. Therefore, you need a diving suit. Furthermore a lamp is necessary. Suits can be borrowed from us. The use of the lamps is contained in the price, as are the tanks and weights. During the whole day trip, you will dive in two different cenotes and the maximum depth will be about 20 ms.
In connection with the dives it is posible to arrange a visit to the famous Mayan-ruins of Tulúm on the east coast.

Conditions: Please, book this diving trip in advance. This fantastic dive is an unforgettable experience for every diver!
