Eagle rays, turtles, lobsters, and horse-eyed jacks should all be on your list of potential sightings.

Paso del Cedral

Animals such as turtles, stingrays, eagle rays, grouper, jacks, angelfish, parrotfish, damselfish, blue chromis, and many more species may be found here. Sting rays and conch may be seen in the grassy area where the dive ends. Definitely a dive site on Cozumel you should not miss.

Palancar Horseshoe

The huge coral formations are the main attraction of this wall dive. This wall’s coral reefs seem like a massive mountain range with deep basins and canyons.

Having strong buoyancy control is essential because of the steepness of the wall. This is a dive not to be missed if you find yourself in Cozumel.

Palancar Caves

The Palancar Caves are another top dive site in Cozumel. Huge coral formations with a complex network of tunnels to explore, and inspiring photo ops for those who want to capture the vastness of the ocean.

You’ll find Paradise Reef right after you enter Cozumel Marine Park. This is a common choice for a night dive or second dive.

Mild, south-to-north currents are the norm. Try to find Sergeant Majors, Grunts, Snappers, and Angel Fish swimming in schools. Octopus, lobster, king crab, and the splendid toadfish are all nighttime catches.

Las Palmas

This is usually the second dive in a series, and the currents might shift in both directions. Las Palmas is a picturesque cliff that plunges from the reef’s edge 40 feet into the water.

Sponges, tiny coral heads, and soft corals stick to the reef. There is a chance of seeing turtles, lobsters, and brilliant toadfish.


Chankanaab is typically a shallow one with calm currents. Chankanaab is also a popular spot for night diving.

Lots of reef fish go home in the coral heads that dot the reef’s landscape. The Caribbean Reef Squid, the Octopus, the King Crab, and the Moray Eel may all be found there.

Wreck C-53

This Mexican Navy minesweeper, the C-53, sank in June of 2000. It is 184 feet long and located 80 feet below the surface on a sandy bottom. Dive access ports have been carved out of the ship’s sides and interior.

The ship is home to lobsters, crabs, eels, schools of glassy sweepers, and sardines. Barracudas and groupers are common in the open water.


Overhangs and aquatic life are abound in the lovely coral reef. At times, the currents can be rather forceful. Separating the two halves of Tormentos lies a narrow strip of sand.

In the sand, you may find lobsters, splendid toadfish, eels, pipehorse, triggerfish, and jawfish. The reef is a riot of color and bustle, with a diverse array of aquatic life. For photographers, this is the perfect second dive.


Divers should be aware of the strong currents at this stunning wall dive. Beds of robust Finger Coral and Elephant Ear Sponges stretch for a considerable distance. In the top 60–70 feet, the majority of marine life will be found.

Turtles, eagle rays, barracudas, splendid toadfish, and nurse sharks have been seen there. An exhilarating high-speed drift is possible around this reef.

Columbia Shallow

Excellent choice for a second reef dive! Its modest depth and gentle currents are perfect for photography. In this area, you can find the greatest concentration of tropical fish in all of Cozumel.

Punta Sur                                                                                                    

The dive site at Punta Sur, Cozumel’s southernmost point, has a spectacular wall. Popular among visitors is a swim-through that involves descending into the Devil’s Throat. At 80 feet, you squeeze into a little tunnel, from which you emerge at 130 feet. As you make your way towards a safe haven, you’ll encounter a network of coral tunnels that will lead you back to where you started.

Punta Sur Cathedral

As the southernmost dive location in Cozumel’s marine park, Punta Sur Cathedral is a must-visit for every scuba diver. Especially impressive is the cathedral part. At about 110 feet, you’ll find a big cavern with plenty of room to swim in.

Lookout for eagle rays, turtles, and reef sharks!
