About Gordo 1
Gordo Banks is a prominent offshore dive site located approximately seven miles from the San Jose del Cabo marina, off Mexico's Baja California Peninsula. It consists of two submerged oceanic mountains, with Gordo 1 being the one accessible for diving. This remote location is highly regarded in the Los Cabos region for its status as a gathering point for large pelagic marine life, offering thrilling blue water diving experiences. The seamount's peak, Gordo 1, rises to about 36.5 meters (120 feet) below the surface. Dives here typically unfold around this pinnacle, allowing divers to explore the depths where oceanic currents bring nutrient-rich waters. The challenging conditions make it a demanding dive, often involving two tanks per outing, with first dives beginning around 8:00 AM and second dives at 10:00 AM after a surface interval. The primary draw to Gordo Banks is the exceptional opportunity to encounter large pelagic species. Divers frequently observe schools of tuna, jacks, and bonitas, alongside marlin, sailfish, dorado, and wahoo. Sharks, including hammerheads and silky sharks, are common seasonal visitors, with whale sharks also appearing at times. Manta, devil, and mobula rays are regularly seen traversing the water column above the seamount. Due to its exposed offshore location and depth, Gordo Banks is considered an advanced dive requiring specific certifications. Divers must hold at least an Advanced Open Water certification, and a Deep Diving Specialty is highly recommended. A check-out dive at local Cabo San Lucas sites is often mandatory to assess and refresh diving skills before undertaking the challenging conditions of Gordo Banks.

Conditions & Currents
Gordo Banks is an advanced dive site due to its remote, exposed location and potential for challenging conditions. Currents can vary, and while some reports note no current, the site is generally characterized by oceanic currents that bring pelagic life but also create dynamic underwater conditions. Visibility can fluctuate, sometimes being very good down to 30 meters (100 feet), but can also be green or average in the upper layers, improving deeper. Water temperatures can be warm, though thermoclines may be present at certain times of the year. Due to these factors, a negative entry might be required, and divers must be proficient in managing their buoyancy and gas consumption, especially with the deep profile. The use of enriched air nitrox (28% optimal) is recommended to extend bottom time and enhance safety margins for the depths involved.
Why dive Gordo 1 from a liveaboard?
Gordo 1 is one of Mexico's signature dive sites. A liveaboard sleeps you on the water and puts you in the water for three to four guided dives per day, including dawn and night dives that day-boat operators rarely offer. You skip the daily commute back to port and reach quieter, less-crowded sites in the same region on a single trip.
Below are the liveaboards that include Gordo 1 on their Mexico itineraries.
