Incredible week - go here to see the BIG stuff!
Had an awesome week! The best pelagic big stuff diving I've had anywhere in the world, mantas on every dive, hammerheads, close encounters with dolphins, tons of sharks and humpback whale watching from the surface. The crew was great, and were willing to take us on a launch between dives to go snorkeling with a school of false killer whales. The captain coordinated with other boats so that we were the only boat at Roca Partida (having multiple boats would have reduced our dives there).

- Saw tons of pelagics and lots of fish life!. Awesome crew, they worked hard and put us in the best position for good diving.. Great people on the boat and time to share stories..

Best diving trip with best crew
This trip to Socorro felt so special, we had an amazing crew taking care of us underwater and on the boat, we were diving so remotely that it felt really unique, the dives sites are magical. Really recommend Nautilus as it’s a really safe company and crew members are really awesome!

Sea lions & whale sharks in the Sea of Cortez!
I just returned from an incredible week in the Sea of Cortez aboard the Nautilus Undersea. The diving was just incredible and definitive trip highlights were diving with the sea lions and snorkeling and swimming with the whale sharks. The boat crew were extremely friendly and worked nonstop and we had 3 amazing dive guides throughout the week. We learned quite a bit about the Sea of Cortez through various nightly presentations on board and also had fun swimming and kayaking during surface intervals. I can’t say enough about our chef as all the meals were fantastic and our hostess was so friendly and always smiling. What an incredible week!

unforgettable experience
The underwater world has surpassed everything seen so far. The crew on the boat was super friendly, helpful and took care of the well-being of the guests. An all-round successful trip. Come back on this boat, the number of guests is ideal, so you don't get in each other's way under water.

The ship and the crew made for a wonderfully delightful dive trip experience.
Of course, the CALIFORNIA SEA LIONS!!! Such beautiful animals. They are comfortable with divers and getting to experience them up close and personal is something i'll remember until my dying day.

- I can't say enough about the care that the crew showed for all of us on board. Everyone was incredibly attentive to my needs. The food, dive guides, captain and steward were, not only incredibly competent, but carried out their duties with a care to detail and fun loving attitudes. Really, a fantastic trip.

Amazing Liveaboard Experience with exceptional diving
I would recommend this trip to any diver interested in exceptional diving.
- Recommended for
- The wildlife encounters were amazing, from pelagic mantas on almost every dive, to 5 different types of shark, some huge, and a school of 1000+ 50 kg to 150 kg yellow fin tuna. Amazing!. The crew was amazing. The captain's leadership in delivering customer satisfaction. From driving zodiac skiffs, to clearing tables on occasion, nothing escaped his attention to detail. All efforts directed at delivering the best experience possible for the divers. The passengers gelled rapidly, with participants from Argentina, Brazil, Switzerland, Austria, Belgium, Taiwan, Canada and the U S.

An outstanding experience, I'll definitely dive with Nautilus again.
Sea lions! Who knew they were so much fun under water :) Good viz and great diving all-round, covering an excellent range of sites (and more dives than advertised - 16 vs the 12). Sundowners and beers (from a very well-stocked bar) under the stars. All made extremely easy and enjoyable by the wonderful staff.

- The staff were all fantastic, friendly, extremely professional but also engendered a relaxed, enjoyable experience. The vessel is in good repair, well set up for diving and relaxing. And the trip is all made very easy and efficient by the shoreside support.
