In the late 90s, the island was declared a Marine National Park as well as a World Heritage Site by the United Nations Educational, Scientific and Cultural Organization (UNESCO). Cocos Island’s water is just teeming with a wide array of rich marine life. In fact, divers flock to this island to take a glimpse at one of its main attractions: the constant large squadrons of Hammerhead Sharks!

Best time to go on Cocos Island Liveaboard

Situated near the equator, Cocos Island is a tropical island paradise with a warm and humid climate. Average temperature is between 24-30°C. The island has beautiful blue skies, yet heavy rain falls are possible throughout the year.

However, divers need not worry since liveaboard trips in Cocos Island are available the whole year round. But if you much prefer to dive in calmer seas and with better visibility, then it’s recommended to do your trip between the months of January and May.

If you are feeling adventurous and are keen to get your adrenaline pumping, a dive encounter with the Hammerhead Sharks may just do the trick. The best time to dive with these sharks at Cocos Island is during the rainy months from June to December. This is because during said rainy months, the high concentration of nutrients in the water attracts the Hammerheads.

Cocos Island is not only about the Hammerhead Sharks. The island is so rich with underwater life that divers keep coming back for more. Go check this video to see more!

  1. Awesome review of the options for diving the Cocos. Its a shame it is such a trek to get there. What season is best for seeing whale sharks at the Cocos?

  4. We did a 10 day live aboard to the Cocos Islands last year and it was just fantastic! The Wind Dancer is a very nice boat with very lovely and amazing staff.

    We had a total of 21 day dives and two night dives. During the day dives, we By day we saw a lot of sharks; some hammerheads, whale shark, blacktips, tiger sharks and whitetips. Currents are sometimes strong but we our dive group were all experienced divers so we had very little problem with it. Divemasters and guides were very experience and competent.

    To give an overview of the boat itself, here is how it’s like: dive deck had large lockers where we placed our fins and other stuff. 3 freshwater showers are situated near the rear dive platform. The boat has a decent camera table, an outside battery charging station and another charging station by the dining area.

    Food? There was plenty of food during our 10 day stay. The dining area can get a bit crowded though at meal time especially during breakfast and lunch, where foods are served in buffet.

    • Please take that my review of the boat does not return the quality of the dive. For any diver looking for a good dive, Cocos is one of the best places to go to, being a UNESCO World heritage site that includes the surrounding marine zone. And the Okeanos crew gets the job done.

      The cabins are kept clean and have been well-built but everything is pretty much average. Do not expect lavishness. There is a TV and a DVD player in every room so watching movies can be done without any other people or distractions, which was a big bonus for me.

      There’s a lot of food for everyone and they always served breakfast, lunch and dinner on time. The food was plain, but satisfying. It wasn’t really something unforgettable which is why I’d be putting in an average rating but definitely not bad at all. The crew always puts on a fair amount of options to choose from anyway.

      The crew gets a higher score because everybody was quick on their toes to assist the guests with our gears and they were very welcoming. There was never an instance where anybody was rude or unprofessional and one of the dive masters was even extra helpful and showed us a good time. The other crew members though just seemed happy enough in doing their jobs.

      The Okeanos Agressor is something that could satisfy your diving amidst the lack of luxury.

  5. My girlfriend and I spent a week diving Cocos Island aboard the Wind Dancer in July 2014. Diving around Cocos Island definitely is the best when it comes to the sharks I should say.

    The Wind Dancer maybe an old boat and have not been modernized and refurbished for long time but the crew on the boat was excellent. The chef is good so food is okay but don’t just expect fresh foods. The crew overall friendly, helpful, skilled and customer-service-oriented; they were the best part!

    The boat is just around 100 ft long but it got 4 decks. The boat is a bit cramped but nonetheless it’s comfortable.

    Dive operations are very well conducted and safety is very well emphasized. We had 7 days of diving and we saw reef sharks, tiger sharks and of course the main attraction, the hammerhead sharks.

    This boat also has a good variety of food and the kitchen crew are amazing and well skilled for foods are not overcooked. Even the beef that was served was medium rare which I totally loved!

  6. It’s important for everyone to know that diving in the Cocos is not for the inexperienced. A lot of things could change in a matter of a heart beat due to strong currents and surges. The dive trip in Cocos Island Island was a big challenge to my skills and knowledge but definitely something that I would do all over again. All the diving was done by the use of a smaller “skiff” and we never had to take our gears and tanks off while we were there.

    Our skiff driver had always been exceptional and patiently waited for us to resurface. Well if he hasn’t done so we might have found ourselves drifting half-way to Galapagos!

    Gears were well taken care of after each dive and tanks were always filled. All we had to do was go off the skiff, shower and find our way to where the sweet-smelling food was. We were pampered by the professionals on board the Undersea Argo and I have great respect for our captain and dive masters.

    Lady luck must have been on our side the entire time that we were on the MV Undersea Argo. Our dives had always been productive with thousands, yes, thousands of reef fish busily swimming along with us.

    There were schools of hammerheads everywhere that it became a problem looking at anything else as they’ve practically blocked other fishes. And the night dive with the whitetips was like a scene I’ve seen only in professional videos. It was breath taking to watch the whitetips on a feeding frenzy at a night dive.

    These sightings proved to be rewarding by the special guests that came with us and there were actually two groups– camera crews from Japan and France who were doing professional shoots. They were very nice and didn’t hesitate sharing their wonderful photos with us. Talking to them post dives were very enriching.

  7. UnderSea Hunter was the best! Cocos Island lies about 320 miles south west of Puntarenos on the Pacific Ocean side of Costa Rica and it took us a day and a half to get into the island but I enjoyed it since it was a different experience to be surrounded by water all the time. It was also the opportunity for us to familiarize ourselves with the boat and everyone else.

    The dive deck was large enough to accommodate all 20 divers on the MV Undersea Hunter. It also had designated storage bins for gears and a sufficient number of electrical outlets to allow the divers to recharge their camcorders easily. The crew can also easily provide rental equipment, should anyone wish to use any and really cam handy when someone forgets a piece of equipment. Personally though, I would recommend bringing your own equipment.

    We enjoyed the various dive sites teeming with different kinds of sharks, mantas, jacks, orcas among other. Turtles used to be present at the dive sites but we had some problems seeing them as there were a good number of Tiger sharks on the area. Tiger sharks love to feast on turtles, which probably why the turtles didn’t turn up on our last dive.

    I guess it is also important to note that the MV Undersea Hunter staff would always prepare mouth-watering treats after each dive.

  9. We did a 10 days trip aboard the Wind Dancer, touring around the Cocos Islands. The boat was lovely and comfortable. The staff was friendly, accommodating and also very professional. We sure can tell that their knowledges of the area are limitless and they take pleasure in educating new comers.

    We completed 22 dives, 2 were night dives. In general, the current is strong so be sure you are experienced enough, we found it hard but we were lucky to be surrounded by almost only dive masters so everybody was helpful. Also, some dives we spent hanging by a wall to only observe the sharks, Dolphins and rays from a certain distance. It was pure pleasure! Diving around the Cocos Islands is definitely a paradise for sharks enthusiast! Hammerheads by tons, 3 whale sharks, loads of black and white tips reef sharks, many Galapagos sharks and we saw a Tiger Shark twice. I could not believe my eyes. There was, of course, so many other schools of fishes.

    One more thing, I found very reassuring that the Wind Dancer’s diving team was aware of the threats faced by the marine life in this area and I was happy to see that they actively encourage people to learn about that and to be very respectful of nature, both in and out the water.

    It will probably take us a while but we sure will be back! Jane

  10. Great experience on the SEA HUNTER!

    I am an experienced diver and I spent the last few years diving all over the world, literally. Diving around the Cocos Island is certainly not a beginner’s business, the currents are way to impossible. The incredible concentration of fish is indeed very impressive. It’s like if all the pretty diving pictures we see everywhere were shot here, around the Cocos. White and black tip sharks, Galapagos, hammerheads, amazing turtles, barracudas and much much more. The island is wonderful and majestic. Uninhabited, pristine and boasting a beautiful waterfall in it’s core. It’s worth getting on land and exploring the island, I encourage the most adventurer to go.

    The organization on the Sea Hunter is extremely professional and designed for underwater photographers. The cabins are comfortable and the food varied and good. I was delighted to be awaken in the morning by the smell of the breakfast being cooked for us. The boat is comfortable, lots of space that you can enjoy and relax. They have a big screen and a good choice of DVDs you can watch.

    It was a long and exhausting trip to get to the vessel but I would do it all over again tomorrow if I could. Stayed a bit in San Jose to cut the travelling in half and then headed to Puntarenas to board this beautiful boat. It’s a once-in-a-lifetime experience that I fully recommend to all the experienced divers of this world.

  11. Long, exhausting journey aboard the Okeanos Aggressor to the Cocos Islands but definitely rewarding. As a shark lover, I feel like I have seen everything I could hope for. More than once we have been able to observe a huge group of Hammerheads and this alone is enough to make the trip worthy. But, it was way more than that. Hundreds of reef sharks, a dozen of Galapagos sharks and 2 tiger sharks. All are very fascinating creatures, all in different ways. Turtles, many schools of fish, wonderful corals and beautiful landscapes. Being on the Okeanos Aggressor for an entire week was comfortable and enjoyable. The boat is great. The crew, professional and friendly. Food and service impeccable. The entire cruise is well driven, focused on safety and providing a great diving experience.

  12. I also did a 10 days liveaboard on the Cocos’s island. I was on the Argo, but I’m afraid my experience was not as enchanting as many. The price is actually way to high for the services we get on this boat. It’s almost 500$ per day, per guest and the service was extremely ordinary. Seemed to me that everything was focused on the submarine for those who dive the big depths. I was clearly paying for all this tremendous submarine operation which I have no interest in. Then I thought maybe I just came on the wrong boat because they did not meet what I call luxury. My cabin was so noisy, like SO NOISY, even with earplugs it was hard to sleep. There’s was a poor service in cleaning, I think it was only one person that had the impossible tasks of doing the rooms and getting towels and the lunch and dining area ready. It doesn’t make sense to me. Whether they need to rethink their priorities and make that clear or whether I need to consider another boat next time.
