After the accidental sinking of the Calypso, the Cousteau
Society embarked on its next expedition aboard the Alcyone, their
newly christened vessel. During their diving exploration at Cocos
Island, the crew stumbled upon a seamount located just over a
kilometre from the shore, which they named after their own ship.
Rising within 25 metres of the surface, Bajo Alcyone greets divers
with all the big-ticket pelagics, including silky sharks, Galapagos
sharks, dolphins, turtles, and sailfish.
While there's always the chance of seeing scalloped hammerheads
while deep water diving in Cocos Island, Bajo Alcyone stands out as
the best spot. Here, divers have the best chances to snap
screensaver-worthy shots of immense schoolsof sharks stretching as
far as the eye can see.
The jagged, guano-stained rocks that break through the water's
surface serve as the inspiration behind the name of this dive site.
Below these rocky outcrops lie cleaning stations that attract giant
manta rays, while the eastern part of the site features a
hammerhead amphitheatre at 30 metres.
As so often is the case when deep water diving in Cocos, you can
expect to see a number of different species of sharks at Dirty
Rock. Silkies, Galapagos and silvertip sharks join the hammerheads
on the list of usual suspects, while whale sharks and tiger sharks
also make the occasional appearance.
There's no shortage of deep water diving in Cocos, and for those
seeking the thrill of depth and strong currents, the submerged
seamount known as Punta Maria awaits. With its pinnacle rising to
within 24 metres of the surface, divers must perform a rapid
descent to find refuge within its shelter. Once in the lee of the
current, divers can relax and take in their fishy
This dive site is a paradise for shark photography enthusiasts,
boasting two additional pinnacles away from the main rock,
accessible only when the currents permit. The main pinnacle is a
hub of activity, featuring cleaning stations frequently visited by
Galapagos sharks. As the sharks approach, they slow down, giving
the cleaner fish a chance to feast on parasites and photographers a
chance to engage their trigger fingers.
