1. Socorro Islands

On a par with the Galapagos and Cocos Island, the Socorro Islands are a world-class UNESCO World Heritage Site boasting a bounty of shark species and numerous pelagic giants in its Pacific waters. The four islands that make up the Revillagigedo Archipelago sit 240 miles from Cabo San Lucas on Mexico’s Baja California Peninsula and are only accessible via liveaboard.

Sharks and Rays Abound

 Diving here is not for the faint-hearted, as deep ocean currents and heavy weather batter the dramatic walls and pinnacles of the island’s coastline. However, for those willing to endure the often-rough 24-hour sea crossing, the rewards are phenomenal. Dive after dive will proffer extraordinary encounters with some true superstars of the underwater world.

Mexico Top 9 Diving

Socorro’s reputation as a world-class shark destination really comes into its own at Roca Partida, where dive after dive showcases the islands’ huge marine diversity. Here, vast numbers of Galapagos, silky, and hammerhead sharks fin lazily into the strong current, while whitetip reef sharks pile up in the crevices along the rocky reef. Large gamefish species such as tuna, wahoo, and marlin are attracted by baitballs of schooling jacks, as well as the occasional sighting of a whale shark or humpback whale. 

Arguably the best place in the world to dive with oceanic manta rays, The Boiler is a submerged pinnacle used as a cleaning station by these gentle giants year-round. Divers can watch from enticingly close by as mantas glide and swoop overhead, seeming to play in their bubbles. The experience is truly breathtaking; a rare opportunity to get up close and personal with these magnificent creatures.

Socorro also has some very friendly dolphins at Cabo Pearce, and no trip is complete without a dive interacting with this delightful pod.

 2. Cozumel

On Mexico’s northeast coast, near Cancun and Playa del Carmen, the island of Cozumel basks in the warm waters of the Caribbean Sea, and its barrier reef is home to an abundance of tropical species. Divers flock here to enjoy easy drift dives along Cozumel’s steep but vibrant walls, with a bonanza of colorful hard corals, sponges, and gorgonians creating an aquarium backdrop for all manner of fish life, turtles, rays, and the occasional reef shark.

A Colorful Aquarium of Marine Life

There are over 45 dive sites around Cozumel, with diving to suit all levels. The southern end of the island has been a marine park for more than 20 years, and the reef here is in particularly good health with 105 different types of coral and over 260 species of fish. In the clear shallow waters of the southern and northern reefs, divers will often encounter hawksbill turtles, eagle rays, and schooling jack, with moray eels, lobsters, and frogfish found hiding amongst the coral heads. Non-divers can also explore the shallower reefs with snorkeling and glass-bottom boat tours to some of the Caribbean's best sites.

Along Cozumel’s near-shore coastline, the dives become progressively deeper and more challenging towards the center of the island. Exciting drop-offs and coral topography create an intricate maze ripe for exploration, and sites such as Palancar Reefs, Panta Sur, and Columbia feature huge coral formations and swim-throughs full of marine life.

Cozumel is within easy reach of Playa del Carmen on the mainland, providing an excellent opportunity for day trips to dive and snorkel the famous cenotes. Accommodation options are plentiful, from large, all-inclusive resorts to small boutique hotels, hostels, and Airbnb.

3. Riviera Maya Cenotes

Even the most seasoned diver is guaranteed to be impressed by the spectacular rock formations and blue-green sunlight typical of the Mexican Cenotes. Located in the Riviera Maya on Mexico's Yucatan Peninsula, this freshwater system of limestone sinkholes, caverns, and caves draws visitors from all over the world to explore the vast network of subterranean channels. Tulum is often used as a base for this exceptional cave diving spot.

Surreal Subterranean Landscapes

Once underwater, follow narrow tunnels that curve and twist, before opening unexpectedly into huge cathedral-like caves. Light and shadow flicker in competition against the ethereal limestone formations, where sunbeams pierce straggling vegetation hanging through collapsed rock.

The crystal clear water is filtered to such an extent that little marine life can survive, however diving here is all about the underwater topography. Snorkelers and divers of all levels can enjoy the unique scenery where large entrance caves connect to dimly lit caverns, allowing a safe introduction to cave diving. At the boundary between the caverns and caves, signs warn of the dangers and technical experience required for full cave diving. Dos Ojos is perhaps the most famous of all the cenotes, and at a depth of 27ft is simple enough for all levels of divers and snorkelers alike. Diving Tulum is a once in a lifetime experience.

4. Isla Mujeres

Two exciting events draw divers and underwater photographers each year to Isla Mujeres on the northeast tip of the Yucatan Peninsula near Cancun. Through the summer months, huge numbers of whale sharks gather to feed on plankton and krill around the shallow waters of Isla Holbox. There are so many whale sharks that snorkeling tours almost guarantee a sighting, and despite a large number of tourist boats, there are generally more than enough sharks for everyone to have an individual encounter. It is also possible to snorkel with these giants further offshore where they feed on bonito and tuna eggs during spawning events. Sightings of whale sharks are less consistent here, but there is a good chance of spotting manta rays joining the feast.

Pelagics Coming in to Feed

Mexico Top 9 Diving

During the winter months, but in particular January and February, schools of sailfish are the big-ticket attraction, and these lighting-quick predators appear in vast numbers around Isla Mujeres. Migrating from the Gulf of Mexico, they shelter in the lee of the Yucatan Peninsula and feast on sardines forced into shallow water by upwellings along ocean ridges. While most visitors opt to snorkel amongst the sailfish, it is also possible to dive with them, and catching a glimpse of these unique fish hunting and bait-balling their prey is a thrilling experience.

While most visitors wanting to dive Cancun will visit Playa del Carmen or Cozumel, Isla Mujeres should not be missed.

Learn more about Isla Mujeres diving.

Practical Information

Diving Season: Year-round. Whale shark season is from June to September, and sailfish season is from mid-December to mid-March.

Water Temperature: 78 to 82oF (25 to 28oC).

5. Isla Guadalupe

Note: Diving in Isla Guadalupe has been suspended indefinitely by the Mexican Government in 2023.

If diving with great white sharks takes your fancy, you’ll be hard pushed to find anywhere better than Guadalupe Island. Diving here is all about the great whites, and this is one of the best scuba diving destinations in the world to get up close and personal with these awesome predators.

Thrilling Great White Shark Encounters

Located 150 miles off the west coast of the Baja California Peninsula, Isla Guadalupe is only accessible by liveaboard. The visiting boats specialize in shark-cage diving. Trips depart from San Diego in the US or Ensenada in the north of Mexico and normally provide three days of diving. 

Mexico Top 9 Diving 

The great white season is from August to October, with numerous lively young males arriving ready to mate early in the season, and the larger males making an appearance from late September onwards. The largest females arrive well into October when the weather is starting to turn, however, this is peak breeding season, and leads to some breathtaking interactions.

While great white sharks are the star of the show, divers will also spot the endemic Guadalupe seals and sea lions feeding on large schools of mackerel while the sharks are distracted by the cages. In addition, the boat journey out and back affords the chance to spot whales and dolphins.

Cage diving in Guadalupe is suitable for shark-diving enthusiasts and beginners alike, and it is possible to experience the great whites with no diving qualifications at all! This makes it a great trip for non-diving friends and family keen for a taste of adventure.

Learn more about diving Isla Guadalupe and read all about diving with great white sharks from our Guadalupe Trip Report.

6. Northern Sea of Cortez

The Sea of Cortez is a 700-mile stretch of water separating the Baja California Peninsula from the rest of mainland Mexico. The northern end of the gulf enjoys a temperate climate and is well isolated from the Pacific Ocean, creating a unique habitat that supports the highest abundance of marine mammals found anywhere in Mexico. The Sea of Cortez region is so valuable to North America’s biodiversity that it is a UNESCO World Heritage Site, with three-quarters of the designated area made up of marine habitats.

Huge Diversity of Unique Marine Life

 Vital to the region’s success is the plankton-rich water supporting a thriving food chain of more than 800 types of vertebrate. Key predators include whales, dolphins, and sea lions, as well as a resident pod of fin whales. However, the stars of the show are undoubtedly the whale sharks that feed in the shallow waters of the northernmost Bahia de Los Angeles during the summer months. Day boats take snorkelers out into the bay to swim with dozens of these gentle giants, and to watch them gorge on the nutritious plankton soup. 

Mexico Top 9 Diving 

From the largest to some of the smallest fish in the sea, the nearby Midriff Islands boast some fascinating macro, with huge numbers of nudibranchs, such as the vibrant but carnivorous sea tiger, playing out a multicolored slow-motion drama. There are also several types of blenny and a variety of jawfish displaying flashy mating colors if you catch them in season. 

This is by far the most accessible liveaboard from the western US; simply fly to Phoenix and then catch a shuttle across the border to the boat. Also on the itinerary of some liveaboards departing from the south, the northern reaches of this fascinating body of water are worth exploring in their own right.

7. La Paz

As the capital of Baja California Sur, La Paz offers visitors access to a great range of diving in the southern Sea of Cortez. If whale sharks and sea lions are on your bucket list, La Paz is a must-visit.

Pelagics Galore

One of the biggest attractions here is the whale sharks that visit La Paz Bay in October and November when plankton blooms are at their richest. Swimming with these gentle giants is a humbling experience and one of the highlights of a La Paz trip. Also, in La Paz Bay, the hammerhead shark nursery, which has been decimated by fishing in recent years, is regenerating, and sightings of these once-abundant sharks are becoming more frequent again. Please note that La Paz Bay is closed for swimming with whale sharks from May until early October each year.

Mexico Top 9 Diving

Further offshore, the renowned El Bajo seamounts are the best place to encounter oceanic pelagics, with mobula rays, hammerhead sharks, dolphins, marlin, and tuna all taking turns to steal the show.

For a unique experience, the sea lion colonies at Isla Los Islotes are great fun to dive amongst, with dozens of curious and playful youngsters providing a circus of entertainment to willing spectators. Just as entertaining is watching the show from the surface, and many visitors choose to snorkel rather than dive. The sea lion colonies are closed for breeding from 1 July to 31 August each year.

8. Cabo San Lucas & Cabo Pulmo

Situated 40 miles apart on the southern tip of the Baja California Peninsula, Cabo San Lucas and Cabo Pulmo catch a diverse range of tropical reef and pelagic species where the Sea of Cortez meets the Pacific Ocean. On the southernmost point, the sheltered San Lucas Bay offers great introductory diving amongst rocky reefs and corridors, where sites such as Santa Maria and Chileno Bay are chock full of critters and small tropical fish, nudibranchs, and lobsters. California sea lions appear in abundance here, too, adding a sense of mischief to the dive. San Lucas Bay is also home to the area’s famous Sand Falls site, where sand that eroded from the surrounding cliffs cascades down ravines to create unusual underwater scenes.

Diving and Snorkelling for Everyone

Further out at the dramatic offshore walls and plateaus of Gordo Banks, oceanic pelagics regularly pass through on migration further into the Sea of Cortez. Humpback and gray whales can be spotted between December and May, and this is also the best time to catch a glimpse of scalloped hammerhead sharks. The diving here can be tricky, with strong currents and rough surface conditions, so is best suited to experienced divers.

Mexico Top 9 Diving

On the eastern side of the peninsula, Cabo Pulmo is a protected National Marine Park covering 27 square miles of the northernmost hard-coral reef in North America. Frailes Rock in the south of the park is home to yet another sea lion rookery, and these youngsters really know how to entertain! The snorkeling is fantastic here, and the shallow waters allow great access to explore the fascinating macro and tropical fish of the inshore reefs.

Through the winter months, humpback, gray, and sperm whales can be spotted around El Bajo seamount (not to be confused with El Bajo at La Paz), where bait-balls of schooling jack offer a tasty pit-stop for these migrating giants. Other open ocean visitors include mobula rays, hammerhead sharks, and the occasional whale shark.

This plethora of marine life also provides a fantastic experience for non-divers, with open ocean safaris offering whale-watching and guided snorkeling with sharks, mobula rays, whales, and many of the region’s other migratory species.

9. Chinchorro Banks

A five-hour drive south of Cancun, protected within the Sian Ka’an Biosphere Reserve, the Chinchorro Banks are a hidden gem on the Mesoamerican Barrier Reef. While thousands of divers flock to the northern resorts of Cozumel and Cancun, very few are aware of the unique biodiversity and pristine habitats found along this isolated atoll. 

Unexplored Reef in Pristine Condition

Diving the banks is only possible from the mainland, and a 30 to 60-minute speedboat ride from Xcalak, Majahual, or Costa Maya will take you out to one of the best scuba diving destinations in the Northern Hemisphere. Relax on easy drift dives over the colorful coral or explore some of the nine fascinating wrecks spread along the reef. French angelfish and queen angelfish school in a colorful patchwork while lobsters, grouper, and stingrays loiter under the coral heads and swim-throughs. The warm, clear waters are perfect for snorkeling, and shallow wreck sites such as Forty Canons are just as intriguing explored from the surface as they are underwater.
