There's a site called Los Islotes, where you can dive and snorkel with a colony of sea lions. This is a world-class experience, and due to Baja's temperate climate, is available year-round.
Neill, Original Diver
The Baja Peninsula, high on Mexico's north-western tip and just south of San Diego and Los Angeles, is separated from the Mexican mainland by the Sea of Cortez, and draws divers for the sightings of Whale Sharks, Gray whales, Sea Lions and Hammerhead sharks
Why we think you’ll love it
The waters of the Sea of Cortez are teeming with marine wildlife; you can time your visit to coincide with the annual migration of the gray whales to and from Alaska, and the area is also fantastic for spotting giant sea turtles and huge sea lion colonies.

Dive Holidays to Baja California: The Detail
The landscape, flora and fauna are very different from most parts of mainland Mexico, but one of Baja's main draws is the climate, which delivers near-constant sunshine, low humidity and sea breezes that keep the temperature from getting too hot. This provides ideal conditions for all kinds of onshore and aquatic activities.
The diving here is in the Sea of Cortez, a unique body of water separated from the Pacific Ocean by the Baja peninsula. It is a young sea, full of nutrients which does mean that the visibility can be lower, but the marine life is plentiful, and that's the draw - you're not here for the coral. Jacques Costeau famously claimed the Sea of Cortez to be 'the aquarium of the world' and by all accounts, it was once absolutely teeming with all manner of amazing marine life. Overfishing in the 80s has had a big impact, but the marine life remains remarkable by any measure.
There are not many places in the world where you can dive with hammerhead sharks, sea lions, and whale sharks all in one day.
Baja is also a world class destination for whale sightings, particularly from November to March. December to March does see a lot of wind and more unpredictable diving conditions, but it's definitely worth it for the chance of whale sightings. Mantas can also be seen by those lucky few, whilst schools of Mobula can sometimes number in their thousands!
