A diving experience I will never forget.

All the fantastic sea creatures we were super lucky to see. Most the dive guides where fantastic. Even though we didn't need any help, I always felt that anything we would have needed was easy to ask for and everyone was more than happy to help.

A good experience

It was good. It could have been excellent if El Niño hadn't warmed the waters so much that large sharks stayed in the main very deep in cooler waters and no whales. The Nautilus Explorer needs a lot of TLC and is showing signs of age in many parts. The crew however was very friendly and thoughtful. Captain Al was great and very focussed on diver safety. The dive briefings were very good but somehow didn't manage expectations well as certainty about seeing certain wildlife transformed itself into disappointment in many circumstances. We had Mantas on every dive though which was fantastic. Overall happy to have done it though other diverson the boat who had been before (some 3/4 times) said these were the worst diving conditions they experienced in the Revillagigedos (aka Socorro). Luck of the draw I guess.

Most amazing way to celebrate 20th anniversary!

So many Great White sharks of different sizes. We were able to renew of wedding vows on the dive deck and we were surprised by unexpected treats to help us celebrate our 20th anniversary. The Captain is amazing, not only in charge but welcoming and works along side the fantastic crew.

A huge Manta was circling above our heads for the whole dive. WOW....he came so close, we could have touched him :-) The Mantas were great, during our trip. The diving at Roca Partida was fantastic: Mantas and all kinds of sharks! And our nightly snorkel with the silky sharks was a adrenalin rush. The silky sharks were hunting the fish and we were inbetween them.....scary!!! Though: at Socorro, the sea was quite empty. At some dives, we didn't see anything besides some Nudibranchs hanging on the wall :-(
