Liveaboard Diving in Bajo Alcyone
What To Expect On a Bajo Alcyone Liveaboard
Liveaboards to Bajo Alcyone will normally be as part of a dive trip incorporating all the sites of the Cocos Islands. Virtually every liveaboard itinerary will stop here for some time, allowing divers to experience some of the best shark diving in the world. Once you jump into the pleasantly warm waters of this famous site, you'll soon realise why divers consistently sail nearly 2 days to get here. Superb visibility, incredible biodiversity, and the sight of circling groups of over 100 Scalloped Hammerheads, give this unbelievable site it's well deserved status amongst the finest scuba diving spots on the planet.
What You Can See
Live aboard dive boats come here for one main reason: Scalloped Hammerhead Sharks. Arguably there's no better place to view these incredible creatures than this isolated spot off the Costa Rican Pacific coast. Their distinct body shape form some stunning silhouettes as they swim in the sunlight above groups of divers, allowing fantastic opportunities for underwater photography enthusiasts.
The sheer numbers of Hammerheads on show will mesmerise even those that are expecting it, and even after a few dives over several days, we've yet to hear of anyone tiring at the view! They are often found in groups of over 100, a site very rarely seen across the entire globe. Liveaboard dive cruises to this region tend to last for at least 10 days, giving guests ample time to dive with these beautiful animals, as well as relax on board in style.
The Hammerheads are present all year round, although they are in their highest numbers during the wet season which runs from June through to December. The dry season however offers the best visibility and calm seas, and so in truth there really is no bad time to be underwater here.
Although the main draw is the Hammerheads (and rightly so), there's no shortage of other marine life to be seen at Bajo Alcyone in addition to the premier attraction. Manta and Mobula Rays are normally present, attracted by cleaning stations in the area. There are also several different shark species to complement what you will have already encountered - including Whitetips, Blacktips, Silvertips and Silkys. It really is a world class site, and a true pleasure to dive at, which will no doubt be one of the main highlights of any liveaboard trip to Costa Rica.
Getting to Bajo Alcyone
As it is within the Cocos Islands, some 550 kilometres from the Costa Rican mainland, diving at Bajo Alcyone is only possible on a dive liveaboard cruise. These normally depart from the port of Punterenas, a 90 minute drive from the country's capital San Jose. Guests can either arrange their own accommodation in the city and then transfer to Punterenas, although commonly liveaboard operators will include these as part of the itinerary.
Getting to San Jose is straight forward as it has a well served international airport, flying to and from many destinations across the Americas. If you are coming from elsewhere, your route will often involve changing in the United States.
Some longer term travellers will arrive in Costa Rica overland also, as it is well connected to it's neighbouring Central American countries.

Incredible - “fish soup” on an open exposed reef with ripping currents ! Challenging but very rewarding - great fun.

1. The first time, I did not hold the rope to dive down, which was very dangerous due to heavy flow, but I saw a lot of hammerhead sharks
