Comments Cocos Island is truly a diver's paradise. Our group flew into San Jose, Costa Rica, requiring an overnight stay in a hillside hotel with beautiful views. After a 3-4 hour bus ride over the mountainous (curvy) highway to Puertorenas, we boarded the Okeanos in the evening and departed immediately. The crossing to Cocos Island was very rough, 36 hours over large swells, necessitating transcop patches AND motion sickness pills for nearly everyone. The staterooms were small but adequate in size, comfortable, and clean, with mostly a double bed and single bunk in each room and one quad room, each with a toilet/shower. They were cleaned daily. We moored in Chatham Bay which was protected and very calm. Views from the boat were amazing with dozens of waterfalls gracing the rain-forested cliffs of Cocos and daily rainbows. Bird life was profuse. Even from the liveaboard, we saw Mantas and dozens of silky sharks from the decks. Every dive was spectacular. Most dives were to 100 feet, all on nitrox, and averaged 50 minutes. There were three day dives and one night dive each day. Dive sites were reached by Panga boats which accommodated 12 divers comfortably, each with built in racks for tanks. The crew set up the tanks and assisted in checking nitrox levels. All dive times, nitrox mixes, and depths were carefully monitored. The crew was very friendly and interactive. Nearly EVERY dive we saw HUNDREDS of hammerhead and white tip sharks, dozens of marble rays, several manta rays and eagle rays, profusions of tuna, bait balls containing thousands of fish, and dozens of eels (many free swimming). There were occasional turtles and dolphins and even a large frogfish walking around. Currents could be strong and could shift direction without warning. Thermoclines occurred at depth, dropping temps to the low 70's. Our group wore 3 or 5 mm wetsuits, with hooded vests, 5mm gloves (needed to hang on to the rocks in current). Divers with cameras had unending photo op as the sharks and whale sharks are unafraid and approach closely. Night dives involved watching packs of white tip sharks in a feeding frenzy, covering the reef thickly like maggots. Overall, the diving was the best in my 32 years of diving anywhere. Cocos Island itself is like Jurassic Park. Access is strictly limited. Only the park rangers live there. There is an extra $245 charge per person to dive the Cocos area, $100 pp fuel surcharge, and $100 pp charge for unlimited nitrox in addition to what we paid for a package deal for flight, hotel, diving, and the liveaboard. But still, worth every penny. The dive crew made a DVD of our diving which amazes everyone who sees it. My thanks go out to the crew. The trip of a lifetime!!
