Home to an array of renowned dive sites, it attracts underwater enthusiasts from all corners of the globe. In this section, we're about to embark on a journey of discovery, unveiling some of the Sea of Cortez's most enchanting dive sites.
Renowned as one of the most spectacular dive sites in the Sea of Cortez, El Bajo is a magnet for underwater enthusiasts, characterized by three underwater seamounts or pinnacles.
The dive site has an average depth ranging from 18 meters (60 feet) to 35 meters (115 feet). Conditions here can be challenging due to currents, but the reward is undeniably worth it. Therefore, this site is more suitable for intermediate to advanced divers (also considering the depth).
El Bajo is famously known for its large schools of hammerhead sharks, typically spotted in the early morning. These elusive creatures gather in the area due to the seamounts' upwelling currents, which bring nutrients to the surface. Additionally, sightings of giant manta rays gliding majestically are also relatively common. But the marine spectacle is not limited to these magnificent creatures. Divers may also witness a colorful array of other pelagic species, including large schools of jacks, tunas, and occasional sightings of whales, dolphins, and marlin.
The pinnacle's structure, covered in anemones, sponges, and corals, provides a refuge for smaller marine life, offering an exciting contrast to the larger pelagic sightings. It's a dream site for underwater photographers!

Aside from the sea lions, divers can also spot a variety of colorful fish species, including parrotfish, angelfish, and sergeant majors, amidst the rock formations. The site is also home to various crustaceans, starfish, and the occasional moray eel, giving divers an excellent snapshot of the Sea of Cortez's biodiversity.
The islets are also a bird sanctuary, hosting numerous species including Blue-footed Boobies and Magnificent Frigatebirds. This makes the surface intervals just as fascinating!
