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!

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.

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..

White shark express
The crew went out of their way to make your experience a fantastic and memorable one. The opportunity to see multiple white sharks from up close was amazing. There was never a wait to get into a cage so you could essentially soak as long as you wanted to! Would recommend this trip and boat.

- Experience white sharks up close in a controlled and safe manner for both the animals and guest, crew and service

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!
