The Wall of Santa Rosa

In Santa Rosa, one of the most vertical walls in Cozumel you will see sensational swimmthroughs, tunnels, groupers, and schools of jacks.
The caves are at a depth of 25 meters (83 ft). Anyway, the wall drops until 500 meters (1650 ft). It has frequent currents that can be strong. In case the current pushes the diver to the bottom, the diver must remain calm and paddle as closely to the reef where the current allows for easy access through the many canyons back to the surface.
The reef is rather plane with a soft decent. To the north of the Wall of Santa Rosa at a depth of 10-12 meters (33 - 40 ft) the wall slopes down sharply. Swimming through the right tunnels across the reef one can take a look at the deep depths as exiting the tunnels.
The walls are filled with gorgonians and corals. Also orange sponges shaped like elephant ears and yellow tubeworms of over a meter in length. Below 20 meters (66 ft) the view is just fantastic. Beneath the canyon openings one can see banks filled with lobsters. The water is so clean and clear that one can see beyond the allowed diving depths.

Palancar Caves

The depths of this dive can reach 30 meters (100 ft). Palancar Caves extend some 5 Km (3 miles) and it is one of the most preferred by divers.
Here the reef not always slopes down sharply, it is quite plane. The wide structure of Palancar has many holes and crevices; it's a real maze of tunnels and pillars of corals. The vault of the tunnels is covered with vibrant orange sponges. The growth of the soft coral is rather scarce than in other places. The reason for this was hurricane Gilbert that damaged the reef at Palancar.
The outside wall of the reef slopes to 30 meters (100 ft) in depth. It leads to a sandy pendent that leads to the Talud. In this part of the reef the visibility can reach more than 60 meters (200 ft). It is preferable to enjoy the entire view than to stop and check the small details. There are all kinds of fauna to be appreciated at this location.

Colombia Wall

The Colombia wall is located at the extremities between the Palancar reef and Punta Sur reef. The area of Talud is simply spectacular. It has massive towers of coral that are 18 meters (60 ft) high toward the surface. Here the reef is wide and can reach depths of 6 to 8 meters (19 to 26 ft). Through the coral platform, beautiful passages form across transversally. At this spot the dives are done along the wall at depths of 30 meters (100 ft). Besides the amazing aquatic views, one can also observe such creatures as sea turtles and eagle rays.
The surface of the reef, the tunnels, and exits are covered by algaes and soft corals and on the walls there are gorgonians and different types of sponges. The presence of many types of fishes are constant. The water is normally transparent. In some cases the currents can transport a great amount of plankton that limit the visibilities of photographers.

Paso del Cedral: Cedral Pass:

It's a very nice dive, with moderate to strong current. A lot of marine life such as groupers, barracudas, lobsters, schools of snappers, nursesharks, green moray eels.
Maximum depth is 15 meters (50 ft).
The coral formations are middle sized but beautiful and surrounded by fish of all kinds. There's a very beautiful cavern to go through.

Tormentos Reef:

The paradise of photographers. Is a shallow place (15 meters, 55 feet) and is formed by colorful soft corals. Small fish are everywhere swimming through the gorgonians. Red finger shaped and orange sponges are amazing and will make your photos perfect.

The sunken ship: Felipe Xicotencatl, C - 53.

It was sunken in June, 2000 in the waters of Chankanaab for the divers to explore it and also to create a new habitat for corals and fish. The maximum depth is 24 meters (80 ft) and you can dive either inside where you'll find schools of glassy fish or in the deck of the ship. It stands straight in the bottom and has three levels to visit. With the proper training and equipment you can do partial and full penetration. The ratio is 1 Divemaster to 4 divers. Different marine life is growing everywhere, lobsters on the sandy bottom, groupers around the deck, and sea urchins, corals, barracudas and small fish are taking this place as their home.
