Scuba Diving In The Sea Of Cortez, Mexico
Sea Of Cortez Diving Highlights
The scuba diving in the Sea of Cortez is all about sea lions, whale sharks, manta and mobula rays, dolphins, huge schools of fish, and fascinating underwater macro life. It is one of the easiest "big animal" destinations to reach and enjoy from the United States.
La Paz, Cabo Pulmo, Loreto, and the northern Sea of Cortez all have excellent diving. You can dive the Sea of Cortez via liveaboard or a dive resort.

Intro To Diving Sea Of Cortez
The Sea of Cortez is a special place situated between Baja, Mexico, and the mainland. Water of all shades of blue sits against an arid desert backdrop and an assortment of islands. The Baja peninsula is home to unique flora and fauna that have evolved in near isolation, so it's no surprise that the Sea of Cortez diving features magnificent marine life. Cabo San Lucas is home to Land's End, a narrow strip of land where the Pacific Ocean meets the Sea of Cortez. There is a famous arch, several unique dive sites, and accommodations for all sides of the nightlife spectrum.
For divers, La Paz is the most popular destination. It is the capital city of Baja California Sur, Mexico, and is situated on the coast about 2 hours north of Cabo San Lucas, on the Sea of Cortez side of the peninsula. Cabo Pulmo is a very small town located between Cabo and La Paz, offering fascinating diving within a protected marine park.
Moving North into the Sea of Cortez we find Loreto, a much smaller destination than La Paz, but also with excellent diving. North of Loreto is very remote and the dive sites are best reached by liveaboard with easy access from Puerto Pensaco, a short drive from Phoenix, Arizona. The cost of diving on the Sea of Cortez is much more affordable than many other destinations where divers look for the same large marine life, and short flights from the southwestern United States make travel easy.
Diving Information
Sea Of Cortez Marine Life & Photography Subjects
The Sea of Cortez has a reputation for whale sharks. During the summer and fall, divers flock to the Sea of Cortez for a chance to swim with whale sharks. These gentle giants generally move south as the season gets later.
Shark lovers should look for bull sharks in Cabo Pulmo, and can see blues, makos, and silkies on a Cabo marine life safari. Hammerhead sharks can be spotted by lucky diver at El Bajo, Las Animas, and Gordo Banks.
During the winter months, mobula rays are quite commonly seen in the Sea of Cortez, especially on night dives.
Another main attraction for diving La Paz are the sea lions, which frolic and play with divers, presenting amazing photo opportunities. Sea Lions are found in a number of places in the Sea of Cortez, but none beat the sea lion colony of Los Islotes.
Other Sea of Cortez marine life includes huge schools of jacks and baitballs, as well as tuna, wahoo and lots of other fish, dolphins, eels, jawfish, rays.
The Sea of Cortez also offers great macro photography opportunities with critters like nudibranchs, snails, jawfish, pikeblennies, signal blennies; and various crabs and shrimps to photograph.

Typical Sea Of Cortez Dive
Pangas (classic Mexican wood and fiberglass boats) are the norm for resort diving. Several operators have larger, more "traditional" dive boats. Resprt-based diving can often involve long boat rides to dive sites - sometimes exceeding two hours each way.
Liveaboards will dive from their tender boats. Dives in the Sea of Cortez can be a shallow "fishbowls" with fantastic vis or deep dives in stiff current looking for hammerhead sharks, so there are options for everyone.

How To Get There
La Paz is serviced by Manuel Mrquez de Len Airport (LAP), with most flights arriving from Mexico City or Guadalajara. Once on the ground, it's a quick shuttle ride to the dive resorts. Divers visiting Cabo Pulmo can fly into Los Cabos International Airport (SJD), which is about an hour away. This is also the airport for Cabo San Lucas.
Loreto has an international airport, however, flights are more limited than in the larger cities. Renting a car is easy, but be aware that insurance requirements in Mexico differ greatly from US requirements an adds a significant increase to the overall rental cost.
Sea of Cortez liveaboards depart from Cabo for southern Sea of Cortez itineraries. For northern and central routes, liveaboards depart from Puerto Penasco, which is an easy shuttle ride from Phoenix, Arizona.
How To Dive The Sea Of Cortez
There are several dive resorts in the Sea of Cortez along with a few liveaboard options. Divers will find most of the diveresorts in La Paz, which is easy to reach.Cabo Pulmo offers limited options and is also easily reached. Beyond that, divers can explore options at Loreto.
Liveaboards like the Rocio del Mar, the Quino el Guardian, and the Nautilus Gallant Lady provide extended range and offer different itineraries depending on the time of year and marine life seasons - a great way to experience the Sea of Cortez.
Best Time To Dive Sea Of Cortez
July to December has the best visibility, often approaching 80 feet (25 meters). We're fans of visiting the La Paz area between October and November, which is prime season for whale sharks and offers warmer waters. The whale sharks are generally found in the bay feeding on plankton, so visibility will be significantly less during these snorkeling sessions. The local authorities allow shorkeling in the Bay of La Paz once a minimum number of whale sharks have arrived, usually betweeen October and April. The whale sharks are also near Bahia de Los Angeles during July-August, and you may be able to snorkel with them during a liveaboard trip.
December to March brings sightings of humpback whales (though you are not allowed to enter the water with them) as well as mobula rays, however, the water is colder with poorer visibility than the summer and fall. Temperatures range from 65F in the winter to 86F in late summer. It can also be windy during the winter months. The Sea of Cortez and Baja Peninsula get hot topside during the summer, but it's a dry heat and the refreshing Sea of Cortez is never more than a few steps away.
As an additional note, if you're visiting La Paz to dive with the sea lions on Los Islotes, please be informed that the colony is closed for mating season each year from June 1-August 31.
Topside & Non-Diving Activities
Sea of Cortez dive resorts offer activities like fishing, kayaking, snorkeling, sandy beaches, dining and lounging by the pool. Keep in mind that swimming with whale sharks is limited to snorkels and no tanks, so it's a great opportunity to bring non-divers on an ocean adventure.
Non-diving activities on liveaboards are limited to snorkeling and enjoying the sun decks, plus whale watching!

Overall ValueConditionsMarine Life Top SideWe traveled to Baja California Sur to dive in both the Pacific and the Sea of Cortez in the same trip. After diving at lands end, where the two meet, the remainder of our diving was done in the Sea of Cortez. We dove in an area called “the corridor". It consists of shallow reefs with schools of fish, moray eels, invertebrates, etc. We also visited a dive site with a phenomenon called a “sand fall". It’s like a waterfall, but underwater and it’s sand cascading down the reef. After dives in this area, we saw a humpback whale migrating north into the Sea of Cortez, toward the area we were headed to next, Cabo Pulmo. Cabo Pulmo is a strictly enforced marine park where the dive sites seem to be untouched. We saw massive schools of fish, huge groupers, loads of invertebrates, and close encounters with bull sharks. Overall, we found the diving here to be excellent. We can’t wait to return to the Sea of Cortez to dive around the areas of La Paz and Loreto.

Overall ValueConditionsMarine Life Top SideThe Sea of Cortez is easily accessible, full of amazing diversity and photographic opportunity and Dora's boats are in their element with staff that are ALWAYS doing their best. The Explore Baja trip is a great value and fine adventure.The "expedition" aspect was particularly enjoyable. Watching the scenery and geology change as we traveled, finding sperm whales, whale sharks, and large pods of dolphins in addition to the more predictable dive findings was a very unique experience. Nirupam's guidance and experience exceeded all our expectations and really topped off the trip.

Overall ValueConditionsMarine Life Top SideI would say the diversity when diving in the Sea of Cortez is just amazing.The Sea Lions and Whale Sharks were the highlight of the trip. It’s pure joy to watch the Sea Lions with their antics as they try to get divers attention and interact with them. But I can’t leave out the Nudibranchs, Giant Jaw fish (with eggs), Seahorse and Bulls Eye puffer (the puppy dog of the sea) along with beautiful seascapes. So much to see it’s hard to take it all in on one trip.The Sea of Cortez shows off her diversity both underwater and topside on the trip to the Midriff Islands.Besides the diversity of the sea life the added bonus is being on a photography trip with like minded guests who were willing to share their experience and subjects. No hurrying during a dive, take the time you need to photograph a subject or seascape.Overall and amazing and enjoyable trip.

Overall ValueConditionsMarine Life Top SideThe dive spots were excellent with wonderful interactions with sea lions and viewing for many other types of sea life I’ve had little opportunity to see in the past. The Sea of Cortez is definitely a wonderful place to dive and I will definitely do so again given the opportunity. This was my first live aboard and it was a very enjoyable experience I would welcome again. The whale shark snorkeling was amazing this time. Views and encounters with these creatures in Baja de los Angeles exceeded previous encounters in La Paz, mostly due to much better visibility.This trip was truly enjoyable for me. I only have great memories and experiences and was able to grow a little bit as a budding underwater videographer. There was no shortage of sea life opportunities with which to try and improve my knowledge and skills. Nirupam is an excellent guide and coach. I’ve been on three trips with him now (twice in La Paz and this one) and I would happily go on any dive trip with him.
