Destination Overview

Your Summer Get-Away Begins Here
Dive the World’s Aquarium

The Sea of Cortez is a diver’s paradise. With its unique ecosystem and the overall natural beauty, have earned a UNESCO World Heritage Site status. We have been diving here for almost 5 decades and every time it has been exciting! Come see firsthand why this sea is called the “Aquarium of the World” and all of it’s natural wonders.

Meet the playful sea lions of Los Islotes, surround yourself in a tornado of big eye jacks and schools of skipjacks. Lets not forget the huge pods of dolphins, turtles, mobulas, sperm whales, gobies, the hammerhead sharks around El Bajo & Los Animas, whales of all types of descriptions, shipwrecks and night dives. And if you’re lucky, giant mantas swimming around La Reina and orcas.

The Sea of Cortez is Vibrant with Life

The Sea of Cortez is loaded with life from huge pods of inquisitive dolphins, sharks, giant whale sharks, friendly sea lions, mobula rays, cow nose rays, sperm whales, swirling tornadoes of fish and sometimes even Manta Rays. Whales of all descriptions visit over the winter and into spring. Huge squadrons of mobula rays numbering upwards of 100,000 aggregate every spring, orcas have been frequent visitors over the last several years. Also, hammerhead sharks migrate into the sea in May and stay until early winter.

Nautilus Scout

Nautilus Scout – Spotter Airplane

Blue whales, giant pregnant whale sharks, orcas and huge schools of mobula rays being our speciality.

Mobulas & Orcas Adventure

Mobulas & Orcas Ocean Adventures

We have you covered with mobulas & orcas. Whether you want to get an early start on an Ocean Safari, or join a liveaboard trip on our 116-ft expedition yacht or try something really exceptional and enjoy a luxury sailing yacht charter with family or small group of friends. We know exactly how to get you onto the schooling mobulas and much more.

April – Mid-July
Ocean Safari – US$295 pp.

Huge Schools of Mobula Rays and the Possibility of Orcas. Spotter Airplane Supported!

8 days / 7 nights. Fly into SJD Cabo for a late afternoon board and depart from Cabo San Lucas. Mobula rays and orcas are resident year round in the Sea of Cortez but the action gets especially hot from late march to mid-July when the mobulas aggregate in large schools.

Where there are schooling mobulas there can be orcas and with the help of our spotter aircraft we achieved a 78% success rate with in-water encounters in 2022. We have also encountered blue whales, solitary pregnant whale sharks, huge pods of dolphins and lots of fin whales on previous trips. Mobulas and orcas encounters are snorkelling and free-diving with the opportunity for additional scuba diving most days at our favourite dive sites.

Special feature if you book on the Nautilus Gallant Lady. We have gained a park permit for underwater lights for night scuba diving at a location usually frequented by schooling mobulas. If the mobulas grace us with their presence, this is the highlight of any trip.

Dive your own way!

Dive Your Own Way

We cater to the entire spectrum of diving experience and fitness. Our super experienced divemasters are there for those who are new to diving. Experienced divers are welcome to explore most of our dive sites at their own pace with or without a divemaster. We are there to guide and critter point for whoever wants it. Note that in national parks, divers are required to stay with our divemasters.

Operated For Safety

Operated For Safety

Safety is a very serious business. Mother Ocean can be capricious and unforgiving. We hold ourselves to the highest standards and you should expect and demand no less. In our view, every dive boat should be operated within a certified ISM safety management system, outfitted with sprinklers, emergency smoke hoods for everybody and the same safety, fire, life saving equipment and radios as the largest cruise ships. Captains, mates and engineers should have professional commercial mariner qualifications and all crew should have STCW professional mariner certification. Safety is not something to publish in a brochure. It’s part of our DNA. A cornerstone of our culture. Something that we have been living by for every day of the last 30 years.
