I went on the Nautilus Under Sea to Guadalupe Island on a 5-day trip to dive with the white sharks and it was an amazing trip! The Nautilus crew were super friendly and professional and were all about safety, making for a really enjoyable trip! The food on board was great and you never went hungry, they did nice interpretive presentations about the sharks in the evenings and were very passionate about shark conservation, which was nice. The rooms were clean and comfy, with nice clean bathrooms and good beds so you slept well on the trip. They have two underwater cages and one surface cage and they rotate you around so you can pretty much be in the water in one of the cages at all times if you wanted to, giving you ample opportunity to see the sharks and get some great pictures! They would yell out "shark!" every time a shark came by which was pretty fun and got everyone pumped! You are pretty much guaranteed to see sharks every day, there wasn't really even an hour that went by when there wasn't at least one shark circling the boat. It's a really cool trip to go on, definitely should be on your bucket list and these guys are the real deal, very professional, highly recommend!

Amazing trip to the Revillagigedo Islands! Staff aboard the Nautilus Under Sea was amazing, as usual. Great food and experience on the boat. Occasional rough seas did not stop them from taking great care of the guests and their camera gear while diving. We saw an amazing diversity of marine life - the whale shark, many other shark species (galapagos, silky, silvertip, white tip, a tiger, etc), dolphins, and of course the beautiful mantas!I also really enjoyed the marine life lectures in the evenings. It was my second trip with Nautilus liveaboards (went to Guadalupe in 2015 aboard the Explorer) and I would definitely return to do a third. Bluewater's photo guide, Erik Lukas, was fabulous also. He took a lot of time to help the guests, regardless of experience or whether they had larger mirrorless/DSLR rigs or people with smaller point and shoot setups. His nightly lectures and photo review sessions were really informative. I felt like I had a decent amount of experience going in, but it was great to learn a ton of new things from a true professional! As always, the staff at Bluewater Travel was very helpful in making arrangements for the trip and answering the many questions we had beforehand. Thanks again for a great trip!

Nautilus Undersea crew is so nice, diving logistics are smooth, and the food is fantastic. The water is colder (68-72F 2024 late June/early July). We were in drysuits and glad we did. The boat has HP100 steel tanks for extra which is a nice bonus for drysuit weighting! The boat is on the older side and can tell its age. I like that there are only 16 divers, so we get to know everyone, and it is not chaotic. We saw many mantas and sharks (white tip/silver tip), a few hammers and dolphins, and lots of fish. We are lucky that the current is not strong and sea is mostly calm :)

We loved our time on the Nautilus around the Socorro Islands. It was a trip of a lifetime for us. Wonderful team, amazing dives and we were well looked after in between each dive. The destination is very remote so you feel I like you are on a real adventure.
