Great option for cocos!

The crew was very friendly and accommodating, food was excellent. Dives were safe and enjoyable. This is a great option to see cocos and more budget friendly than the alternatives.

Saw tons of hammerheads, a whale shark, and enjoyed the underwater life in the pacific.

Great diving. Great food. Brilliant adventure

Diving was brilliant. Cocos Island is cool, so many waterfalls. The diving was really well organised, the staff on the boat worked really hard. We were worried about the food, as my husband has Coeliacs, but the attention to detail on this was superb, they brought out gluten free options whenever required. Also the staff at Liveaboard.com were great, they jumped straight onto a mix up with my booking, it was really easy to get hold of them on the phone, and the mix up was sorted straight away.

Recommended for
Very relaxed atmosphere. Catered brilliantly for gluten free. Well organised.

PuraVida in this JurassicPark like environment

What a special island, and a special feeling to be lucky enough to have been there. Crew was amazing, dives were warm and with good viz, many hammer heads around, eagle and marble rays, dolphins etc... although the best season apparently ranges from August to October, with colder waters and loads of sharks. PuraVida !

HammerHeads. Crew. PuraVida.
