Dive Equipment & Setup
Dive Area & Sites
Cocos Island, located 550 kilometers off Costa Rica's Pacific coast, is one of the world's ultimate big-animal diving destinations and a UNESCO World Heritage Site. The island's remote volcanic seamounts attract enormous schools of scalloped hammerhead sharks — often numbering in the hundreds — along with whitetip reef sharks carpeting the rocky ledges at night. Giant oceanic manta rays, whale sharks, and silky sharks are regular visitors, and the deeper waters harbor marlin, sailfish, and yellowfin tuna. Bottlenose dolphins escort dive boats, and massive schools of jacks and barracuda create swirling baitballs against the blue water backdrop. The volcanic rock formations are encrusted with colorful cup corals and black coral trees, creating a dramatic stage for some of the most exhilarating diving experiences on the planet.

Insurance Recommendation
We strongly recommend all guests to purchase comprehensive dive accident insurance and trip cancellation insurance before departure. Dive accident insurance covers medical treatment, hyperbaric chamber costs, and emergency evacuation in the event of a diving incident. Trip cancellation insurance protects your financial investment, not only if you need to cancel or cut short your trip due to personal illness, injury, or other unforeseen circumstances, but also if the trip is postponed or cancelled by the operator due to severe weather, technical issues, or other operational reasons. In the unlikely event of operator insolvency, cancellation insurance can also help recover your payments. Please ensure your policies are valid for the entire duration of your trip and cover the planned activities.
Medical Form Required
A valid dive medical certificate or an accepted medical form is required for all guests on this vessel. You can submit a doctor's certificate confirming your fitness to dive, or complete and sign the medical form yourself if the form and operator permit self-declaration. If your answers or the operator's rules require medical clearance, a doctor's approval is mandatory; signing at your own risk does not replace it. Permission to dive remains subject to the operator's requirements. Download the form, complete it for each guest and upload the signed document in your booking area.
Rental Gear
Regulators: $60–$90 per voyage · Buoyancy Compensators (BCD): $60–$90 per voyage
