Spectacular shark encounters
The almost 6m tall "Lucy" and another female of almost the same size, which were often very close to the cages. Sighting of a total of almost 30 different great white sharks. The information from the professional crew about the sharks and their distinguishing features was also great. This gives guests the opportunity to photograph a shark that has not yet been registered and to give it a name. The spectacular jumps of the sharks out of the water were also sensational.
- Recommended for
- A great experience to experience the great white sharks so closely, the warmth of the crew and the possibility of unlimited cage diving.

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!

Excellent
Diving trip done in August 2025. We really enjoyed our time on the Nautilus Undersea. Crew was amazing and worked very hard at making we were happy and comfortable. Safety of guest was taken very seriously. Well organized. Swimming with Whale Sharks was great. We did one night dive and it was the best night dive we have ever done so far. Boat is a bit old but we were comfortable. No complaints at all. We are already planning our next dive trip in Socorro with them.
