M/V Argo

The Argo features nine cabins all with private bathrooms, alongside a lounge, dining room and spacious sundeck, but what really sets this boat apart is its exceptional dive facilities.

All standard diving gear, including nitrox and rebreather facilities, are offered on board, while photographers can also store their cameras and strobes in a safe vicinity. To get to the most secluded dive sites, three powerful tender boats are available to shuttle divers to and from the main vessel. Finally, there's a team of 14 passionate and friendly crew members on hand to ensure you have the trip-of-a-lifetime, be it via their exceptional knowledge on the marine park itself or from the talented chefs cooking up a storm throughout the journey. Guests can also complete their Nitrox specialities on board during the epic 36-hour voyage to the Cocos Islands.

Trips last ten days and explore some of the most coveted dive sites in the world. As well as the array of schooling fish, eels, manta rays and even the occasional friendly whale, the voyage is spectacular for sharks; Galapagos sharks, white tip reef sharks, blacktip sharks and scalloped hammerheads are frequently spotted during dives, with hundreds of these odd-headed beauties often seen at Bajo Alcyone. And then, of course, there is the DeepSea Submersible. The Argo's very own submarine allows guests to explore the deepest depths of the ocean to seek out some of the ocean's rarest, and sometimes, undiscovered creatures. This is a real bucket list adventure.
