Top 7 Dive Sites in Baja California Sur, Mexico

March 23, 2026 Angela Zancanaro

A lot of people come to Cabo San Lucas, Mexico and head straight out to Socorro on a liveaboard, and for good reason. But there’s some really solid diving right here along the Baja Peninsula that’s absolutely worth checking out. Plan on taking an extra day on your trip to Cabo while you’re vacationing on Mexico’s beaches.

Baja isn’t universally known as “the best diving in the world.” and I think that’s important to say upfront that It’s seasonal. Visibility can change, water temperatures fluctuate a lot. Some days are calm and glassy, and other days remind you that you’re practically in the Pacific Ocean.

However there are days when hammerheads cruise through the blue in huge schools, the baby sea lions are chewing on your fins, and when massive schools of fish stack up on a reef. On those days, Baja absolutely feels world-class.

Accessible beginner sites, deeper advanced dives, and even a shipwrecks that have turned into their own little ecosystem. If you know where to go, and when to go, it’s unforgettable.

These are my favorite 7 dive sites in Baja California Sur, broken down into a dive guide for you.

🦭 Los Islotes – La Paz

There are dives that are just so impressive and then there are dives that make you laugh into your regulator. Los Islotes is the second one. Juvenile sea lions zip through the water like underwater puppies, blowing bubbles at your mask and darting through your fins. It’s playful with non stop laughter every step of the way, and completely unforgettable. It's low key one of the most fun dives in the world, and I still surface smiling even after a lot of dives here.

The site itself is made up of rocky formations and small caves surrounding the sea lion colony, which sits on the exposed rocks above the water. The southern side of the island is typically shallower and where most of the playful interactions happen, while the northern side drops deeper and sometimes attracts larger fish moving through the area.

Best Season:
September through November. The sea lion pups are newly born and extremely playful during this time, which leads to the most interactive dives.

Closure Period: June 1st to August 31st (closed for mating season)

Level:
Beginner friendly, Open Water certification

Typical Depth:
20–60 ft (6–18 m)

What You Can See:

Playful juvenile sea lions
Lots of reef fish
Sea stars and rocky reef life
Occasional schooling jacks and sardines
Moray eels

🦈 El Bajo – La Paz

El Bajo is a completely different kind of dive from Los Islotes. Instead of playful wildlife and shallow reefs, this is true blue water seamount diving. You descend into open ocean and settle in along the rocky structure, watching the blue for movement. When conditions line up, schools of hammerheads sometimes cruise past, and the whole dive becomes about staying calm and taking it in.

The site itself is made up of three underwater pinnacles that rise from deep water far offshore. These rocky towers create strong current lines that attract schooling fish and larger predators moving through the area, which is why divers typically stay close to the structure while scanning the surrounding blue water.

Best Season:
Late summer through fall (August–November) when warmer water and current bring in pelagic species and the chance of seeing hammerheads is higher.

Level:
Advanced dive, Advanced Open Water certification

Typical Depth:
60–100+ ft (18–30+ m)

What You Can See:

Scalloped hammerhead sharks
Large schools of jacks
Tuna
Occasional mobula rays
Other passing pelagics

🚢 Fang Ming Wreck – La Paz

The Fang Ming is one of the more unique dives in the La Paz area. Originally a Chinese cargo ship that had been seized for illegal fishing, the vessel was later cleaned and prepared before being intentionally sunk in 1999 to help create habitat for marine life and expand diving opportunities in the area

The wreck now sits upright on a sandy bottom and has developed into a thriving artificial reef. Schools of fish move around the structure, growth has taken hold along the hull, and one of the coolest parts of diving the Fang Ming is coming around the structure and finding a green sea turtle casually resting on the deck of the wreck.

Best Season:
Late spring through fall (May–October) when turtles are most commonly seen resting on the wreck and marine life is especially active.

Level:
Intermediate dive, Advanced Open Water certification

Depth:
60–80 ft (18–24 m)

What You Can See:

Green sea turtles
Large schools of fish around the wreck
Reef fish gathering along the structure
Occasional rays or larger fish passing by

🐠 La Reina – Cerralvo Island

La Reina is probably one of my favorite dive sites in Baja… but shhhh don’t tell anyone. It’s the perfect chill summer dive spot, big schools of fish move through the area, octopus and eels hang out in the rocks and sea lions sometimes drops in to play with you. During the summer months the seamount can also act as a cleaning station for oceanic manta rays, which occasionally visit to have smaller fish remove parasites. It’s not something you see every dive, but when it happens it’s an incredible encounter.

The site itself is an underwater seamount that rises all the way to the surface, where a small sea lion colony rests on the exposed rocks. The reef slopes down from the rocks to a sandy bottom around 40 feet, making it a fairly shallow dive that’s easy to explore. Divers can swim around the base of the seamount and through a canyon that cuts through the rock where sea lions often come down to play. Just outside the seamount sits the remains of a small wreck that has developed impressive coral growth and attracts plenty of marine life.

Best Season:
Summer through early fall (July–October)

Level:
Beginner friendly - Intermediate dive (depending on current), Open Water certification

Depth:
30–40 ft (9–12 m) Wreck sitting a little deeper as 22m

What You Can See:

Manta Rays
Sea lions
Sea turtles
Octopus
Moray eels
Schools of reef fish
Coral growth around the nearby wreck

🐢 Pelican Rock – Cabo San Lucas

Pelican Rock is where a majority of the training dives happen in Cabo, but don’t let that fool you. Being so close to the Pacific and sitting inside the protected waters of Cabo San Lucas Bay, there always seems to be something new to see here. Even though it’s considered an easy dive site, the mix of reef life and occasional pelagic visitors keeps it interesting no matter how many times you dive it. Guides have reported everything from whale sharks to passing schools of hammerheads here. More commonly though, you’ll see plenty of reef fish, lobster tucked into the rocks, birds diving for baitfish on the surface, and the occasional sea lion or mobula ray passing through.

The dive typically begins over a sandy bottom around 10 meters (about 30 feet), where the main rock structure rises from the sand. From there the reef slopes down toward a wall that drops into a deep submarine canyon where the Sea of Cortez meets the Pacific. This drop-off is part of what attracts so much life to the area, and it’s also where the famous sandfalls can sometimes be seen spilling over the edge like an underwater waterfall.

Best Season:
Year-round dive site, but late summer through fall offers the warmest water and often the most active marine life.

Level:
Beginner friendly, Open Water certification

Depth:
20–60 ft (6–18 m)

What You Can See:

Sea turtles
Lobster
White tip reef sharks
Reef fish
Moray eels
Mobula Rays

🦈 Gordo Banks – Cabo San Lucas

Gordo Banks is one of those all-or-nothing dive sites. Some days it’s absolutely epic with walls of hammerhead sharks or even the occasional humpback whale passing by in the distance. Other days you might descend into open water and see nothing but tiny zooplankton drifting in the current. Both realities are possible here.

The site itself is a remote offshore seamount located far from the coastline. The pinnacle rises up from deep water but the top still sits around 40 meters (130 feet), so most recreational divers never actually reach the bottom. Instead, divers typically descend partway along the ridge and hold position in the current while watching the blue water above and around the seamount for passing pelagic life.

Best Season:
Late summer through fall (August–November) when pelagic species, including hammerheads and large schools of fish, are more frequently encountered.

Level:
Advanced dive, Advanced Open Water certification required. Most operators require a checkout dive beforehand due to depth and strong currents.

Depth:
80–120 ft (24–36 m)

What You Can See:

Hammerheads sharks
Silky sharks
Large schools of jacks
Tuna
Occasional other pelagic species

🐂 Bull Sharks – Cabo Pulmo

Bull sharks in Cabo Pulmo tend to be seen at one of two sites depending on conditions, either Las Casitas in the south or near the El Vencedor/shipwreck in the north. Because Cabo Pulmo is a marine protected area, only a small amount of dive operators are allowed to visit each dive sites at specific times. Before heading out each morning a park ranger draws from a hat to determine which of those sites will be open that day. After that, dive guides draw numbers to determine the order they get to choose sites for their groups. Because of this system, it’s a good idea to give yourself a couple days of diving here if seeing bull sharks is high on your list.

Las Casitas is a mix of rocky reef and sandy bottom with scattered coral growing over the rocks. It’s a more open dive site without a lot of vertical structure, which makes it easy to settle in and watch the surrounding blue water. Bull sharks will often cruise slowly through the area, passing along the reef and circling back again.

The northern site is near the El Vencedor shipwreck, a tuna fishing vessel that sank during a storm in the 1980s and now sits upright on the sandy bottom. Over time the wreck has become an artificial reef covered in marine growth and surrounded by schools of fish. Divers usually position themselves near the wreck structure while scanning the blue water where bull sharks often appear.

Best Season:
Late fall through winter (November–February) when bull sharks are most commonly seen in the area.

Level:
Beginner friendly, Open Water certification

Depth:
40–60 ft (12–18 m)

What You Can See:

Bull sharks
Sea Turtles
Large reef schools
Healthy coral systems

Water Temperature & Wetsuit Guide for Baja California Sur

Baja diving is seasonal, and water temperature changes a lot throughout the year. This isn’t tropical Caribbean consistency — it’s Pacific influenced.

Here’s a general breakdown:

Winter (December–March)
Water Temp: ~65–72°F (18–22°C)
Recommended: 5mm–7mm wetsuit, many divers prefer a hooded vest

Spring (April–June)
Water Temp: ~68–75°F (20–24°C)
Recommended: 5mm wetsuit

Summer (July–September)
Water Temp: ~75–85°F (24–29°C)
Recommended: 3mm wetsuit or even shorty on very warm days

Fall (October–November)
Water Temp: ~75–82°F (24–28°C)
Recommended: 3mm–5mm depending on your tolerance

Visibility also shifts with season. Summer and fall tend to bring warmer water and better pelagic action. Winter can have incredible marine life but cooler temps and occasional plankton blooms.

If you run cold, bring more suit than you think you need. Multiple dives a day on a boat will chill you faster than you expect.
