Dive sites and activities: Cocos Island, including Dos Amigos, Manuelita, Bajo Alcyone, Dirty Rock, Punta Maria; shore visits/island hikes can be arranged

Day 1 and 2
After a 90-minute shuttle bus from San Jose International Airport, you will arrive for boarding and departure during the evening. Once on board the Nautilus Explorer you can relax on the sundeck while the cruise embarks on its way to the Cocos island. It takes approx. 33 hours to reach the island. Meals will be served during the crossing.

Days 3-9
Each dive will be introduced by a briefing done by the guides on board to give you details about the sites and marine life you are about to see. Cocos Island is famous for being one of the hottest shark diving destinations in the world. The schooling scalloped hammerheads are legendary. In recent years, tiger sharks have become more commo, whitetip reef sharks and silkies are common. Other species regularly encountered include Galapagos, blacktip, silvertip, and guitar sharks, as well as many species of rays, especially around the cleaning stations. It’s easy to get lost in mesmerizing giant schools of big eyed jacks and mutton snapper.
The 'rainy season' is from June through December, when the deep ocean upwellings attract manta rays and whale sharks. In September, humpback whales can be spotted in the sheltered anchorages.
The food served during your safari is a mix of Mexican and western style cuisine. A continental breakfast at 7 am features fresh baked goods, a fruit plate, homemade granola, cereals, yoghurt, toast, fresh orange or mango juice, and oatmeal. A cooked breakfast is usually served after the first dive and is a mix of buffet and cooked-to-order: eggs, cheese omelets, sausages, hashbrowns and toast. The 2nd dive of the morning is usually at around 11 am, then its lunch time when here is a great variety on offer at the buffet, from homemade Italian pizzas and fish tacos, to quesadillas and fish burgers. Tropical fruit and salads will help you stay well hydrated. There is a 3rd dive of the day in the early afternoon at 2:30 pm. Then snacks and sunbathing for the rest of the day. Dinner is served at 6 pm, which will be an array of both Mexican and American style meals, plated, or buffet style.
Day 9 does not include a full day of diving due to early departure from Cocos.

Day 10 and 11
After the long ocean crossing, the liveaboard returns to Puntarenas and check out is after an early light breakfast. You will be transferred either to your hotel or to San Jose Airport.
