Swimming with Sea Lions?

For snorkelers and scuba divers, swimming with sea lions is an enriching and memorable experience available only in a few select locations worldwide. At Cabo Private Guide, we are fortunate to have access to these exceptional places where you can interact with these marine creatures while encountering other remarkable wildlife, such as humpback whales, sharks, whale sharks, and mobula rays. Sea lions are known for their extreme playfulness and interactive nature. They will come face to face with you, mimicking your moves and blowing bubbles. Witnessing them hunt vast schools of sardines is an unforgettable sight.

Getting to Know Sea Lions

Sea lions belong to the family Otariide and are pinnipeds characterized by elongated arms, external ear flaps and the ability to walk on four legs. California sea lions, in particular, exhibit a light to chocolate brown coloration, with males being much larger than females and displaying a distinct sagittal crest. With a life expectancy of 15 to 20 years, male California sea lions can reach up to 2.5 meters (8.5 ft) in length and weigh up to 500 kilograms (1,000 lb), while females grow up to 2 meters (6.5 ft) and weigh around 100 kilograms (220 lb).

The Californian Sea Lion is native to the western coast of North America, ranging from south Alaska to central Mexico. The Gulf of California holds the highest concentration of these marine mammals. They are highly adapted to coastal areas and can be found in various habitats within their distribution range.

Californian Sea Lions are carnivores and primarily feed in coastal areas. Their diet consists of anchovies, sardines, mackerels, rockfish, herrings, squids and other cephalopods. They don’t chew or break their food but swallow it whole, ensuring efficient prey consumption.

Behaviors and Breeding: Socializing and Vocalizing

Sea lions are incredibly social and gregarious animals. They gather in large numbers on beaches or rocks, often engaging in physical contact with one another. Among the most vocal mammals, sea lions bark incessantly during the breeding season. Females initiate sexual interaction approximately three weeks after delivering their pups. Gestation lasts for 11 months, and pups are nursed for about six months before becoming independent at a young age.

Status Protection and Predators: Conservation Challenges

Great white sharks and killer whales are the natural predators of Californian Sea Lions. However, these charismatic creatures face other threats, such as entanglement in fishing lines and nets, which pose significant risks to their population. The increasing pollution in their habitats has also contributed to an alarming rise in cancer cases among California sea lions.

Cabo San Lucas: Dive into the Sea Lion’s Domain

Season: November to April

In Cabo San Lucas Bay, you can fulfill your desire to encounter sea lions almost every day between November and April. Dive sites like “Pelican Rock” and “Lands End” are popular hotspots where you can witness these charismatic creatures up close. As you dive into Cabo, you might even witness the mesmerizing spectacle of sea lions hunting sardine bait balls, akin to an incredible ballet on stage.

La Paz and Its Surrounding Islands: Unleash the Playfulness

Season: September to May

La Paz offers a fantastic adventure for those seeking interactions with sea lions. The Los Islotes sea lion colony, along with the ‘overspill colony’ of San Rafaelito, houses one of the largest populations of California sea lions in the Baja Sur area. Swimming near the colony is restricted during their mating season (June 1 – August 31), but you can dive and snorkel with playful adults and pups from September to May. September and the following months are enchanting as the playful sea lion pups actively engage with their surroundings.

Cabo Pulmo National Park: Where Adventure Meets Biodiversity

Season: November to July

Cabo Pulmo National Park is a unique and popular diving destination renowned for its diverse marine ecosystem. While exploring this area, you may encounter large bull sharks, known to frequent the region throughout most months of the year. Although not as playful as the sea lions in Cabo San Lucas or La Paz, these charismatic creatures are known to interact with snorkelers, blowing bubbles and occasionally posing for photographs. Don’t miss the opportunity to combine a bull shark dive with an encounter with sea lions in this thriving natural sanctuary.
