RECOMMENDED DIVE SITE: Gordo Banks, Pelican Rock

WHY: The world famous school of mobula rays, humpback whales, hammerhead sharks, and colony of seals. Famous first as a resort destination and second as a scuba destination, diving in Cabo San Lucas is easy enough for a true beginner yet offers challenges for even the most expert diver. We love it so much we hosted our latest GTS event there!

MARINE LIFE: Could Cabo have it all? Humpback whales, huge school of mobula rays, hammerheads, silky sharks, dolphins, seals, mantas, and many many more.

WHEN: Good all year round, December – March for humpbacks, June – August for mobula rays.

WATER TEMPERATURE: 24c – 27c (June – November is the warmest)

DIVE WITH: Dive Ninjas for local scuba diving, Cabo Shark Dive for shark diving (freediving/snorkelling), Pelagic Safari for pelagic animals (freediving/snorkelling only), Adventures in Baja for custom tours.



*Note: great all year round except September (hurricane season and they get all the bad weather from the entire Caribbean).

WHERE: Cozumel is Mexico’s largest island, located 10 miles off the Yucatan Peninsula, and easily accessible by ferry or air. In contrast with the mainland resorts, Cozumel offers a more relaxed and laid back feel.

RECOMMENDED DIVE SITE: Palancar Reef – named by Jacques Cousteau as one of the best scuba diving spots in the world.

WHY: Part of the Great Maya Barrier Reef, the world’s second largest reef system. The island is separated from the mainland by a deep oceanic trench which creates a funnel for the consistently nutrient rich currents and therefore attracts lots of wildlife.

MARINE LIFE: Eagle rays, nurse sharks, lots of tropical fish

TOPOGRAPHY / DIVE TYPE: Coral pinnacles rise from a sandy bottom which slopes slowly down to a drop-off.

EXPERIENCE: Because of its generally good visibility and shallow nature, this makes a good wall dive for beginners.

WHEN: December to April

WATER TEMP: Temperatures of 77 to 84°F (25-29°C)

DIVE WITH: ScubaTony


WHERE: On the Caribbean side of the Yucatan peninsula, along the Riveria Maya coastline.

WHY: Bull Shark Dives

MARINE LIFE: Every year dozens of these large sharks arrive to the sandy shallows just offshore. No one quite knows why they are here but some think it has to do with their birthing patterns and others believe it has to do with the freshwater waterflow from the cenotes

TOPOGRAPHY / DIVE TYPE: Shark Dive, generally divers will stay near the sandy bottom to watch and not move around too much.

EXPERIENCE: Intermediate to Advanced. Not to be attempted by beginners

WHEN: November to March

WATER TEMP: Temperatures of 77 to 84°F (25-29°C)

MARINE LIFE: Nurse sharks, dolphins, turtles, reef fish.

TOPOGRAPHY / DIVE TYPE: The underwater museum (MUSA) is a collection of installations from the famed sculptor Jason deCaires Taylor. The idea is to relieve tourism pressures on other nearby sites and to act as a catalyst for new coral growth. Reef dive.

DIVE WITH: For any dive trips in Cancun and Playa Del Carmen talk to our friends at Yucatan Dive Trek – tell them GTS sent you!

If you are in Cancun why not make the trip over to Isla Holbox to snorkel with whale sharks in the summer months?


WHERE: Isla Mujeres lies just to the north of the peninsula, not far from Cancun and boasts a number of great shallow sites.

RECOMMENDED DIVE SITE: Afuera, about 25 miles (40 kilometers) from Isla Mujeres.

WHY: Whale sharks are the largest fish in the sea, and Isla Mujeres is perhaps the best place in the world to get in the water with these creatures (only to snorkel not to dive).

MARINE LIFE: Whale sharks. Some scientists believe that this region annually boasts the largest congregations of whale sharks at any one time.

TOPOGRAPHY / DIVE TYPE: Shallow reef / island

EXPERIENCE: Snorkel / Beginner

WHEN: June to September

WATER TEMP: Temperatures of 77 to 84°F (25-29°C)


WHERE: Head inland and south from Playa del Carmen and more experienced divers will relish the chance to explore one of the longest submerged cave and cavern systems in the world. Angelita, car wash, pet cemetery and the pit are also must-sees!

WHY: The Yucatan Peninsula is in fact a plateau beneath which runs a system of underwater caves, some of which collapsed into sinkholes.Mexico is perhaps the best destination in the world for an introduction to cave diving.

RECOMMENDED DIVE SITE: Dos Ojos (Two eyes). These two cenotes appear like two eyes peering into the underworld below. These are two very different cave systems, which start and end in the same place. The first dive called ‘The Barbie Line’ is a 500m circuit and, leads divers along the opening of the second eye, containing plenty of daylight and provides a lot of space for divers to explore the huge columns and stalactites. The second dive is called ‘The Bat Cave Line’ and is the darker of the two and leads to an air-filled bat cave where there is little light penetration.

TOPOGRAPHY / DIVE TYPE: Cave and Cavern. Stalagmites and stalactites.

EXPERIENCE: Intermediate to Advanced

WHEN: All year round!

WATER TEMP: 77°F / 25°C

WHERE:This unbelievable coral atoll is found off the coast of Costa Maya, not far from the border between Mexico and Belize.

MARINE LIFE: The scuba diving on the atoll is pristine and offers high visibility and diverse healthy marine life and reef. The atoll covers 300 square miles (800 square kilometers), is protected by a Biosphere Reserve and is home to wrecks, drift dives and colourful reefs. You’ll find gorgeous examples of black coral, brain coral and huge barrel sponges.

TOPOGRAPHY / DIVE TYPE: Wall / Reef / Wreck. With less than 1% being above water, this atoll has been witness to almost 200 wrecks, which date back to the 16th century.

WATER TEMP: Temperatures of 77 to 84°F (25-29°C)

WHERE: The town of Xcalak is on the southernmost on the Mexican Caribbean coastline, just off of Belize. Xcalak is located within the Xcalak Reef National Marine Park, a Federal Marine Park with strict environmental regulations, both in the water and out. Xcalak also has the unique advantage of being located less than an hour from Banco Chinchorro, the largest coral atoll in the Northern Hemisphere.

WHY: A hidden diving gem full to the brim of incredible marine life. Families of manatees call Xcalack home, schools of huge tarpon fish, sharks, dolphins and much more. This isolated (in the good way) part of Mexico has to be Girls that Scuba favourite dive destination in Mexico.
