Trip of a lifetime

Diving the cocos islands was always a dream for me, well the trip lived up to the dream. Great organization from start to finish. Diving world class, all the staff onboard professional and on hand to ensure diving and life onboard ran smoothly. Diving the cocos islands is not for the non experienced diver, strong currents and tiger sharks require the respect they deserve..seeing all the wildlife up close in the natural environment is the reason you go to cocos. Total respect is paid to the wildlife and environment, no feeding, no touching, no chasing...just dive and experience the true nature all around. Thank you to all the staff, and thank you to all the dive staff for making the diving feel safe but at the same.time a great adventure.

Truely amaizing diving

We had an amazing time on board the Argo. Diving was excellent!! We saw all we had expected and more!! You can never get tired of hammerheads, tigers, galapagos, silvertips, mantas, eagle rays, marbled rays... But if you do there are lots of other things to see from sea horses to dolphins. The Argo staff was the best ever. So professional, friendly and helpful. They made the whole trip run super smooth. Thank you!!

Excellent accommodations and very relaxing and 5 stars for the meals

The weather was excellent and the diving was outstanding. It was so nice to disconnect from the rest of the world for 11 days and just relax and enjoy the diving. This isn't a trip for inexperienced divers given the depth of each dive. It was very fast pace diving, not much room for error and each diver must equalize quickly and get down fast. I was be going back again.

Once in a lifetime

Few people in life have the opportunity to be submariners; this boat affords you that opportunity. It’s challenging diving but unquestionably worth both the time and money.
