Extremely well run and organized operation coupled with a great destination!

Abundance of large apex predators, and otherwise large amounts and variety of marine life. Dove one dive with humpback whales vocalizing throughout the dive - amazing. Being provided with an opportunity to dive to 300 meters in the onboard sub was incredible, a definite bucket-list event. Could not have been more pleased with the friendliness, capabilities and professionalism of the crew - they go the extra distance to ensure you can extract the best of the diving available.

Total professionalism of the crew and operation, wildlife (land and sea) and comfort.

Freaking Amazing!!!!!

The boat was well thought out for the comforts of a diver from the deck layout, electric outlets to the towels!!! The sleeping rooms were spacious and had ait of room for storage. Things ran very smoothly from communicating with the boat prior to the trip, pick up at hotel in SJ, all the diving and meals, and the return. I would definitely go with the Argo again! Next time I'll have to try the submarine. The crew and guides were amazing. They helped to accommodate every request with a smile.

the trip of a lifetime & amenities to match

I had such a wonderful time at Isla del Coco! The diving was sublime, we saw so many sharks!! I loved each of the dive guides on this boat, they were very knowledgable about the dive sites & shark behavior, without being too controlling. Argo itself is a very nice vessel, it's the nicest cabin I've ever had by far. The food was delicious, and the whole experience was top-notch. I hope to return in the future!

Absolutely Epic Dive Experience and Amazing Hospitality

We had an amazing group and crew which made an already epic dive experience that much better. It seemed like a national geographic expedition with 5 star service and we were fortunate enough to have a solid group of divers from all over the world. Our dive masters were very experienced and we were able to see 12' mantas, walls of hammerhead, tiger shark, white/black tip, galapagos, silky sharks and on our last day a magnificent 20' whale shark. Truly epic dive experience that i can truly say was the best of my life.

Best shark diving in an unspoiled environment

Best dives were Alcyone, Small Dos Amigos and Dirty Rock. An always smiling professional crew and the impressive pristine and prehistoric seeming Cocos Island itself
