Dive sites with The Cortez Club
El Bajo – Marisla Sea Mount is a world-renowned underwater mount for advanced divers. Between 16 and 25 metres, this site is famous for large schools of hammerhead sharks circling the peaks, alongside tuna and jacks.
Los Islotes features a rocky reef and natural arch that serves as a home for a large colony of California sea lions. It is accessible to all levels and offers the chance to interact with these playful mammals amidst schools of sardines and blue and gold royal angelfish.
Salvatierra Wreck is a cargo ferry resting on a sandy bottom at 18 metres. Accessible to beginner divers, the wreck is roughly 70% intact and has become an artificial reef hosting diverse marine life, including exposed propellers and cargo trucks.

Marine life around Mer de Cortez
The waters here are home to impressive pelagics and seasonal visitors. You may encounter hammerhead sharks, silky sharks, or bull sharks, as well as whales including Blue whales, Humpback whales, and Fin whales, which are present year-round. From October to May, whale sharks may also be spotted.
In the reef environments, you will find a vibrant array of life including Grouper (Epinephelus), various species of Snapper (Lutjanus), and large schools of jacks and tuna. The rocky reefs and pinnacles are adorned with Sea fan (Gorgoniidae), brain corals, and soft corals, providing a backdrop for colorful tropical reef fish.

Diving conditions
Divers should be aware of constant currents at sites like La Reynita, which can make certain dives more dynamic. Some offshore expeditions, particularly those targeting marlins, can encounter heavy swell and wind-driven waves.
While many sites are accessible to beginners, others require more experience due to currents or the nature of the terrain. Always check with the team regarding the specific conditions for your chosen site on the day of departure.
