She is a 36 metre boat built for long range expeditions to destinations like the Cocos Islands on 10 day itineraries.

The huge extended dive platform is often used as a swim deck or launching platform for the kayaks between dives, it is also a popular gathering place for sightings of large fish including shark activity. The sun deck is furnished with loungers, tables and chairs and is the perfect place to catch some sun rays or watch the sunset. The chefs use this area to host their BBQ’s along with dancing under the stars; the large open area was actually designed specifically for landing a helicopter.

Route Options

This beautiful island with its breathtaking marine life, including large pelagics, guarantees an unforgettable trip.

The Cocos Island Marine Park, a world heritage site, is a crown jewel of Costa Rica and was pronounced “the most beautiful island in the world”. Spend a full 6 days diving the pinnacles around the perimeter of the Cocos Island with divers usually averaging three dives per day at depths of 18 to 30 metres. Countless fish, eels, lobsters and many other critters are residents of the hard coral reef and adjacent sand slope of Manuelita Coral Garden while the elusive rosy-lipped batfish can be found at Lobster Rock. The phenomenon of the 'bait ball' can also be observed when little bait fish seek protection by forming a spinning ball.

Arrival Day

You must arrive at least one day prior to the boat departure date. Upon arrival to San José, we can have transportation waiting for you (please contact us for a quote) or you can take a taxi to your hotel. There are always taxis available at the airport, even minivans for those of you who carry a lot of gear. We can also recommend and arrange accommodations for hotels in San José. Please note that we do not pick up from all San Jose hotels.

The evening before boat departure, an Undersea Hunter representative will fax you to confirm your pickup time the next day. The evening is at your leisure. Air transport, airport transfers, hotel nights and meals before and after the cruise are not included in the charter.

Day 1

The following day, generally between 8 AM and 1 PM we pick up from certain hotels and transfer everybody by bus to Puntarenas where you will board the vessel. The drive takes about 2 1/2 hours and gives you a chance to view the lush forest and rich farmland of the region.

Due to occasional low tides our boats may need to depart from the pier earlier in the day. Should this occur, you will be transferred by skiff to the vessel. When all passengers have arrived on board, the vessel will take a 32-36-hour cruise out to Cocos Island.

Day 2

A travel day. There will be time to arrange dive and camera gear as well as enjoy the Pacific and the sunshine. Also, the group of incredibly experienced divers provides plenty of stories to pass the time. There are videos and the experience of the Captain and crew to help you get excited for the diving...as if you need them. In addition, you may want to take this time to take one of our diving courses.

Days 3 - 8

Spent diving the pinnacles around the perimeter of Cocos Island. Divers usually average three dives per day at depths of 60-100 feet (18-30 meters) or more. This, of course, is what the whole trip is about.

Day 9

Make the last 3 dives before the cruise back to Costa Rica and reality!

Day 10

All day to discuss the diving and to compare your adventures!

Day 11

Arrival to Puntarenas. Immediately after breakfast you will be transported back to San Jose. We strongly recommend staying one more night on land, before flying out, in case of any unforeseen delays.

Optional tours

While you are here in Costa Rica it is certainly worth the extra time to visit other aspects of the country that truly make it a natural wonderland. Very active volcanoes, white water rafting, mountain biking, some of the most pristine jungles in the world, coffee plantations, horseback riding, visits to craft centers, and of course, some of the most beautiful beaches in the world are among the activities and destinations available in the country. We would be happy to arrange one day tours or longer trips to more remote areas at the client´s request. Recommended Costa Rican companies will operate these tours.

This phenomenon occurs when the little bait fish, upon being hunted, seek protection by forming a furiously spinning silvery ball. This is an attempt of a small species to intimidate and confuse a predator. In a bait ball you can find different bait fish and different hunters. Sometimes the bait fish will be trapped between the surface and the hunters below. This is when the boobies and frigate birds will join the feast. These special events can happen anywhere and at anytime.
