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!

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.

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.

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