Where to go diving in the Sea of Cortez.
1. La Paz
La Paz, the capital of Baja California
, is the perfect place to experience some of the best Mexico diving. Bordered by arid hillsides, this tranquil town has turquoise waters, idyllic sandy coves and easy access to world-class scuba diving. Jacques Cousteau could not have described it better when he said the Sea of Cortez is the ‘aquarium of the world’, and La Paz is no exception.
Los Islotes, a colony of over 200 Californian Brown sea lions, is the place to go swimming with sea lions. As well as hosting plenty of cheeky sea lions, Los Islotes has shallow dive sites suitable for all levels and is a popular night diving spot.
The Baja Seamounts
are ideal for advanced and experienced divers visiting La Paz. Washed by strong currents, these seamounts attract mobula rays, turtles and whales. You can sometimes also see hammerhead sharks, humpbacks and sperm whales there.
Wherever you choose to dive at La Paz, the waters are bustling with reef and pelagic fish, groupers, moray eels and more.
- Love wrecks? Go wreck diving at the Fang Ming and Salvatierra wrecks near La Paz. They are both thriving artificial reefs.
2. Cabo Pulmo
When you ask about Mexico diving and the Sea of Cortez, two things always get mentioned – huge schools of fish and mobula rays! The Cabo Pulmo National Park is renowned for both and is also home to the oldest reef on the west coast of North America, which is a staggering 20,000 years old.
This ancient reef hosts more than 6000 different marine life species and offers spectacular coral reef diving. If you love underwater photography, go there. Macro fans will be delighted with the array of hidden treasures to find, whilst other divers enjoy diving with bull sharks, sea turtles, mobula rays, astonishingly large schools of jacks and colorful reef fish.
Tens of thousands of mobula rays visit the Sea of Cortez every year, creating one of nature’s most impressive spectacles. You can see thousands of these rays in the waters off Cabo San Lucas, Los Cabos, Loreto and Cabo Pulmo. Attracted in spring by plankton blooms, these acrobatic rays gather in huge groups to mate and give birth.

- Go Mexico diving from March to late November for the best chance of snorkeling with mobula rays.
- Visit Isla San Pedro to go swimming with sea lions.
Sitting on the east coast of Baja California Sur, Loreto offers a wonderful mixture of old-world Mexican charm and luxury amenities. With the impressive Sierra Giganta mountains to the west and the ocean on its doorstep, Loreto is a great place to combine diving in the Sea of Cortez
with adventure activities and a spot of pampering.
The nearby islands host plenty of accessible dive sites, many of which sit in the protected waters of the Parque Maritimo Nacional Bahia de Loreto. Expect striking underwater cliffs and deep walls that plunge into the inky depths, caves and boulder-strewn landscapes. There you will find abundant fish life and huge sea fans. All of which make Loreto a top highlight of Mexico diving.
- Go diving at La Lobera, a magnificent wall dive site with deep caves, caverns and black corals.
4. San Ignacio
Mexico is famous for its friendly grey whales, which migrate to the shallow waters of San Ignacio Lagoon to mate and calve from January to April each year. Whilst you cannot go diving with these charming whales, you can take a boat trip from San Ignacio to meet them.
