Diving

Nautilus Under Sea offers 2 different Itineraries depending on the season.
Socorro Islands (a.k.a. the Revillagigedo Archipelago) November - July
Soccoro is well known for its giant mantas which seek out intimate interactions with the divers. You will have the opportunity to encounter resident pods of playful dolphins, may also see up to 10 varieties of shark: schooling scalloped hammerheads, solitary giant hammerheads, Galápagos, whitetip reef, silver-tip, silky, tiger and oceanic whitetips. The list also includes whale sharks and dusky sharks and on occasion even a thresher shark.
The itinerary includes four dives per day (subject to weather and unforeseeable circumstances)
Guadalupe Island July - November
Great white shark encounters at Guadalupe Island are nothing short of spectacular. Guadalupe feels like a remote outpost at the end of the earth but is actually incredibly easy to get to. The trips start from San Diego, California with coach transfers to Ensenada, Mexico. Guadalupe Island It’s the best destination in the world for calm, clear water and a consistently high probability of multiple shark encounters per day.
