A Brief History of Cozumel: Why Cozumel Tourism is Built on Diving

To understand why the reefs of Cozumel are so pristine you have to go back to the beginning. There was never a large indigenous population here to overfish the reef or fishing fleet profiting from plunder. For a large portion of the last three centuries, Cozumel was more or less unpopulated until the explosion of dive related tourism. Modern Cozumel depends on tourism, particularly dive tourism to flourish.

In ancient times, Mayans revered Cozumel for the temple Ix Chel, goddess of fertility. Cozumel was the second most holy place behind Chichen Itza, and many young women would make the 12-mile ocean pilgrimage for blessings of familial abundance. The island thrived for hundreds of years until the Spanish arrived, bringing smallpox with them. The population collapsed, and Cozumel was left virtually deserted for the next 300 years, except as a pirate outpost.

In 1848, following The War of the Castes, Mestizos and Mayans found refuge on Cozumel. Small economic booms, like the gum trade and a WWII air and anti submarine base, spiked the local population, but nothing lasted until Jacques Cousteau introduced the world to Cozumel’s fabulous coral reefs. From then on, it was only a question of how many people could get to the island. The airport upgrade in the late ’70s and the deep water pier in the ’90s opened the doors. Now nearly 4 million people a year visit Cozumel, many of them to enjoy scuba diving.

The North Equatorial Current Makes Drift Diving a Cozumel Special

The North Equatorial Current flows to the west just north of the equator. As it approaches the Caribbean Sea, water is funneled through the Yucatan Channel – where it narrows and gains strength. Right at the mouth of this channel sits the 30-mile x 10-mile island of Cozumel.

The current sculpted the limestone mound of Cozumel into the shape of a torpedo. The sharp, southern tip points directly into the northerly current. The flow splits to either side of the island and reconnects behind the blue, north end. A shallow recirculation zone is formed before the two streams rejoin and head into the Gulf of Mexico.

The current brings crystal clear water, feeds mountainous coral reefs, and propels divers along some of the most exquisite walls in the world. It can be a diver’s best friend or worst nightmare. Either way, come prepared for the MOADD – Mother of All Drift Dives.

Cozumel’s Has the 2nd Largest Coral Reef in the World

The Mesoamerican reef starts by Cozumel and extends south through the Caribbean. It’s the second largest barrio reef in the world. You can’t see the entire reef in one dive, but you can see 50’ high towering coral walls with complex canyons, and many swim through caves.

Coral reefs are built by invertebrate animals called Cnidaria. Related to jellyfish, but they secrete calcium carbonate to form a hard exoskeleton, which is what creates the reefs. They live in a complex symbiotic relationship with zooxanthellae, a single cell photosynthetic organism. These organisms provide the majority of the food to the corals, who in return build structure for them to find shelter and reach sunlight.

Coral reefs rely on warm, shallow seas and sufficient current to provide essential nutrients. In return, they provide food and shelter to nearly ¼ of the ocean’s biodiversity. No wonder Mexico created the Cozumel Reef National Marine Park to protect this resource. Part of your dive fees on Cozumel is for park entrance, which in turn protects this vital resource.

Cozumel Dive Map

Below is our Cozumel Dive Map. It’s compiled from multiple sources including first-hand visits, local dive shops, literary searches, satellite imagery, and boat traffic monitoring. It’s not intended for navigation, but for trip planning with a local experienced dive shop. We hope to inspire you to dive Cozumel for yourself. It tells the story of the top dives sites on Cozumel and what you might expect.

Currents, winds, the experience of the divers on board, or traffic from other shops might influence where your dive crew takes you. Understand that they are here for not only your safety and enjoyment but that of the entire boat you’re with, so always respect their safety decisions.

Cozumel’s Top Dive Sites

The naming of Cozumel’s dive sites can be somewhat interpretive since they are almost all drift dives. Cozumel Scuba Life often plans their dive days where they start halfway down one reef and finish on another. This reduces the total pressure on the reef and allows their divers to see a wider variety of critters. For the sake of communication, I’ll look for a significant dive site or geographic marker to communicate the general dive profile of the area.

Diving Barracuda / the North End

The north end of Cozumel is subject to heavy current and separation from the group means that the diver drifts past the island. Not for beginner divers, these sites feature large deep hog-back reefs and the opportunity for large pelagic sightings including the local reef’s namesake fish – barracuda. Dive sites include:

  • San Juan
    Skill Level: Advanced Depth: 60′ Formations: ★★✩✩✩  Marine Life: ★★★★✩
    San Juan is a difficult site on the northern end of the island. It is often a second dive on a Barracuda trip.
  • Barracuda
    Skill Level: Expert Depth: 100′ Formations: ★★★✩✩  Marine Life: ★★★★★
    Barracuda features large deep hog-back reefs and the opportunity for large pelagic sightings including the namesake fish – barracuda.

Shore Diving Cozumel’s Hotel Zone

Hurricane Wilma pummeled Cozumel in 2005 causing significant damage to the shallow reefs and the famous airplane wreck in front of La Ceiba Hotel. Resorts have been putting in attractions like the Mayan Pyramid, so shore divers have something to see. Certain sites, like Paradise just south of the cruise ship pier, make for fantastic night dives.

If you love shore diving, you should look for a dive resort where your dive boat can pick you up at the dock. This is also a way to save on taxi services to and from the dive shop which will typically run about $10 a day USD. Scuba Life Cozumel is not only a top-notch dive shop, they offer additional 5-star services such as hotel dock pickup from the following resorts:

Shore Diving Sites

Dive Description for the Western Walls and Reefs

Cozumel’s west side offers a little of everything to divers. Just inside of Arrecifes de Cozumel National Park, there is a line of reefs in 60′ of water which are perfect for a second dive or beginner diver. More advanced divers can check out the outer walls at 90′ or some areas where the fast current keeps down the crowds (I’m looking at you Punta Tunich). Several dive sites are close enough for shore diving or searching for unique critters like elegant toadfish. Best of all, the shallow water makes for crystal clear photography without having to color correct, as long as you are not too deep.

The onshore support for diving in the Marine Park is incredible. Cozumel’s medics created a rapid response system so they can be at a hotel dock within minutes of your captain radioing for help, most likely before the dive boat can make it in. With docks located less than a Km apart up and down this coast, help is never far away. Cozumel International Hospital even has a hyperbaric chamber. You never plan for failure, but it’s good to know that support is available if you need it.

  • Punta Sur – Devil’s Throat
    Skill Level: Expert Depth: 130′ Formations:  ★★★★★  Marine Life: ★★★✩✩
    The Devil’s Throat is an iconic dive for expert divers. The throat opens at 80 ft down, taking you through a coral tunnel deep inside the magnificent pinnacles. You drop at a 45-degree angle until you reach the exit at 130 ft. Needless to say, you have to be spot on with buoyancy and breathing before you attempt this dive. Coral mazes abound on Punta Sur so you will have plenty to see while your air holds out.

  • Maracaibo
    Skill Level: Expert Depth: 120′ Formations:  ★★★★✩  Marine Life: ★★★★
    This is the southernmost dive site on Cozumel. Proximity to the open ocean subjects divers to high seas and strong currents but offers the opportunity of large pelagic sightings. This site has beautiful structure including a large underwater arch with a base at 120.

Diving Cozumel’s East Side aka “The Other Side”

Cozumel’s Other/East Side is worlds away from the sheltered western port. Here, surfers take on waves that have traveled all the way from Cuba. It’s rough, rugged, and remote which makes for difficult diving with high consequences. Boats have to go a long way to reach these sites with all the support services located on the docks from which they came. You can find shore diving off the beach road that runs along the south-east side of the island, but be wary of the surf, current, and undertow.

The east side offers relatively undisturbed reefs and unique spots like cannons from a 1761 shipwreck. Every now and then the wind shifts and blows west to east. This makes the western dive sites rough and choppy while the eastern sites now enjoy the shelter of the island.

Dive Seasons of Cozumel

Cozumel is a year-round diving destination where water temperature average 25°C/77°F in the winter and 29°C/85°F in summer. December through April is the high season for diving in Cozumel. May and June offer a chance to visit the island before the summer heat (and rains) set in. July through September is rainy season where it’s hot and muggy. There will always be an afternoon shower with the chance of heavy storms. October and November is the perfect shoulder season to visit Cozumel where the skies are clear, the sea is still warm, and there are travel deals to be found.

Cozumel is home to many sea creatures, but it has a few special seasonal visitors. During the winter months, divers might see eagle rays gliding over the sand. Loggerhead turtles come to nest from April through July followed by green turtles June through September.

Surface Intervals in Cozumel: What to do When You’re Not Diving

  • Wine and Dine in Centro Cozumel – Cozumel is a thriving tourist town with fun restaurants, hopping bars, and plenty of shopping. We loved the taco plate at Machete and drinks at Wet Wendy’s (We came for the name and stayed for the specials). There is simply too much good food to mention it all.
  • Parque Benito Juarez – Here you’ll find the quintessential Cozumel sign and a fountain that features a synchronized light and music show. Nearby San Miguel church makes a beautiful backdrop for pictures. What we loved about Benito Jaurez is that locals and tourists enjoy this park together and you very much get the feeling of being in small-town Mexico.
  • Mega beach resorts- The south end of the island features hopping beaches with much more than just umbrellas. At Playa Mia Grand Beach Park, there are floating inflatable playhouses, boat rides, snorkel tours, and you can still sit under an umbrella drinking a drink with an umbrella.
  • Scenic snorkeling tours– Why stop at one beach when you can take a snorkel tour. Take a scenic boat ride down the coast to enjoy snorkel of El Cielo Bay where you’ll see starfish gardens and the colorful Columbia Reef. Then head up to Playa Mia where you can have romping fun in the sun.
  • ATV Adventures to the Jade CavernsRide ATV’s through the jungle to reach the Jade Caverns cenote, one of the largest in Mexico. You’ll swim in the cenote, travel through El Cedral Village, and see the Coral Cove cave system.
  • Zipline Chankanaab Park – Start your day ziplining across the beautiful clear water. Chill after your thrills at the world-class Chankanaab Beach or explore the park’s botanical gardens and crocodile habitat.
  • Atlantis Submarine Tour – Do you want to show your friends what diving is like or just can’t get enough of the water? The Atlantis XII takes you on an underwater adventure to the C-53 ( Felipe Xicotencatl) wreck and along the coral wall. The best way to see the water without getting wet!
  • Explore the San Gervasio Ruins – Mayans lived on Cozumel long before the Spanish set foot on the island. Mayans took a pilgrimage to Cozumel to worship Ix Chel, the goddess of fertility. It’s an opportunity to see a less visited Mayan site with a unique history.
  • Visit the Mainland – A 45-minute ferry ride gets you over to Playa Del Carmen. You can explore the town or try other scuba adventures like a bull shark dive or diving cenotes from dive shops that are walking distance from the ferry dock. A little outside of town you can explore Rio Secreto or snorkel year round with turtles in Akumal Bay. If you make it down to Tulum be sure to check out the Sian Ka’an Biosphere.

Parting Thoughts on Cozumel Scuba Diving

We were blown away by our experience scuba diving in Cozumel. We have traveled across the world to dive near Hikkaduwa Sri Lanka, Koh Tao Thailand, and Koh Phi Phi Thailand, but Cozumel rocked our world. The viz was A-MAZE-ING, and there was plenty to see between the colored coral and the huge fish.

Scuba Life Cozumel did a fantastic job. We wanted to partner with a first-rate dive outfitter, and we soon realized why Scuba Life Cozumel is the top-rated scuba shop on the island with over 550 5-star ratings! We loved the joy and enthusiasm of their entire staff. They didn’t just love diving, they genuinely loved working at Scuba Life Cozumel. The DM’s were professional and on point, and the equipment was high quality and in good repair. Even though they sponsored us on this trip, we can’t recommend them enough.

If you get a chance to dive in Cozumel – take it. If you get two chances – go twice. It’s just that good!
