Intense dives in a very friendly atmosphere.
Great week - the day of watching and swimming with the whale sharks was awesome! We saw several of them and to be so close to them was magical! The dives where the sea lions came to watch US! 😉

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).

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!

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.
