Nice diving, best crew.
For the price of this liveaboard and the park fees (500$), I suggest to go only in winter season, with better currents and much more marine life. Divemasters can push harder to find marine life instead taking pictures to sell to divers at the end of the trip. Anycase, exceptional service of all staff and incredible destination.

Cocos Island, wild & Natur pur
Die Fahrt, das Meer, die Korallen & neben allerlei Haien auch der eine Manta und die eine Schildkröte. Wasserfalltour mit Neopren. In dieser Umfrage fehlt ein Verbesserungs- bzw. Kritikfeld: Der von mir im Vorfeld erfragte Handyempfang auf Cocos ist nur in einer Bucht möglich (immerhin). Über Roaming ging dort das Heimnetz. Lokale Simkarten (Klaro, Movimento z.B.) sind ausgeschlossen, nur Kölbi (ICE) funktioniert. Diese Info hätte ich gerne im Vorfeld gewusst & entsprechend die richtige lokale Simkarte besorgt. Das Erlebnis getrübt wurde dadurch allerdings nicht.

Okeanos Agressor I is a nice and confortable boat. Coco Island is like in the movies and it's very pleasant to have opportunities to explore it a little bit. We were lucky enough to see all the big stuff under water. Dinners like at restaurant!

World-class diving, friendly and professional staff
The two favourite dive sites - Dirty Rock and Punta María - and the night dives has offered me a magic that i will never forget. The island is intact, true nature, the sky is full of shiny stars. On the top of this the staff is really professional and ready to serve the guest with the highest possibilities with a big smile. Lifelong experience. Thank you.

Trip of a lifetime
The diving was incredible, one of the best places in the world to dive hands down. The food was plentiful and of high caliber, there was almost too much too eat. The crew was very hospitable and catered everything almost too well. The captain needs to realize that this trip is for the costumers and getting in the way with his huge camera while diving was an inconvenience. Although, his photos are amazing and I am happy that he provided them to us. But when a client is having an amazing experience with a Tiger shark, Hammerhead, Galapagos etc. the last thing they want is to have someone move in front of them (or their camera) to get a better shot.

magical diving in Cocos island
My reason to go to Cocos island was to see sharks. I saw a lot of them, mainly hammerhead sharks, whittip sharks and some tiger sharks. The hole experience was amazing. Thanks to the chef who prepared delicious food every day.

Diving wirh the sharks was one of the most incredible and rewarding experiences of my life.
Diving with the hammerheads, white tips, and rays. Being in the ocean experiencing and being part of the ecosystem. And feeling safe thanks to Warren and the other dive masters. Also seeing the dolphins surrounding the panga on one of the dives. The food and service was excellent. Muchas Gracias!

amazing liveaboard adventure
Great trip. I'm already planning the next one to a different point in Costa Rica. The only drawback has nothing to do with the Okeanos: seemingly due to national politics, the park fee to Cocos Isl has doubled two years ago to roughly $500.There has been a lot of grumbling about this. Thus, I won't be going back to Cocos until, hopefully after the next prime minister's election, this policy is amended to a more reasonable price.
