Dive of a lifetime.
Some of the best diving I've ever done. Great staff with loads of knowledge. Calm seas. All types of sharks. Ah the whale shark tried to kiss me. If you see dolphins, instead of pointing a camera at them, play with them. Spin and flip. They'll join you.

Amazing trip!
Overall, this was the best diving I have ever done. We had so many mantas, dolphins, sharks, whale sharks on every dive. The entire crew was friendly and helpful! I have a dietary restriction and the chef did a perfect job of accommodating me and the food was delicious. The boat itself is not the best, a little noisy and has treacherous stairs to the lower deck, I didn’t get hot water even one time in my room, and there was black soot/ash on the top deck that got all over my feet, clothes, everything. Despite this, overall amazing trip.

Whale sharks, sea lions, and mobulas in Sea of Cortez - the highlight of my summer
The highlights of the trip were the "Safari" trips with speedboats. The diving part was not that spectacular, although interesting - we had about 20 dives total, which seems not much for a 9 day trip (the trip technically is 11-day event, per the description, but we arrived after 6pm and left the boat at 8:30am, so no activities on those days) The program promises a lot of other activities and sea creatures, but I am happy with I saw and encountered. The whale sharks were definitely a unique experience, although I have mixed feelings about that, as I think that in some way we disturbed their peaceful day jumping around them and swimming quite close to them - they were not going away, so I hope that they were not stressed very much. The crew was very good and helpful both on the diving side as the boat service side. I wish the information would be better. The cabins and boat equipment was basic, but I did not expect much more. I am very happy with this trip!

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.
