Guadalupe Island (Mexico) is the top destination for Great White Shark encounters. This small volcanic island located in the Pacific 240 kilometers (150 miles) off the west coast of Mexico’s Baja California peninsula outperforms both South Africa and Australia with shark-seeing consistency and watching conditions. Only Guadalupe Island can boast shark viewing in beautiful clear blue water with 40–45m (125–150ft) visibility. Nautilus Explorer, the sistership of Nautilus Belle Amie and Nautilus Under Sea, recently counted 108 Great White Sharks in the bay where they stage the submersible cage diving operations guaranteeing unforgettable encounters.
Socorro Island is all about diving and interacting with the friendliest giant mantas in the world. These are true giant mantas, Manta Birostris (aka manta ray), and should not be confused with the regular and smaller Mobula species, which can be seen far more often. The Giant Pacific Mantas that will greet you at Socorro are the largest of the rays and we believe they are the most majestic creatures in the ocean. At Socorro, these giants choose to interact with divers! They come in very close - less than 1m (3ft)! - make eye contact with you and then swim along beside you - totally on their terms. What is even more extraordinary is that the local population of Bottlenose dolphins, have learned to mimic the behavior of the giant mantas. It is very likely that these wild dolphins will also move in close and intimate to divers during your trip.
Shark sightings are also very good at Socorro Island with common sightings of silky, galapagos, hammerhead, white tip and silver tip sharks. Whale sharks are usually spotted at the beginning of and the latter part of our season. A population of 1200 humpbacks moves into the island's waters in January and chances are excellent that you will have encounters with these mighty giants. You may even hear them singing through the hull of the ship at night as you lie in your bunk. Schooling hammerhead sharks may be seen at any time but the best chance to see large schools up close is April - June.
Nautilus Under Sea operates excursions that take you to some very interesting locations during the best times of the year. This liveaboard offers unforgettable unique nature experiences in amazing diving locations. It is adventure diving at its best!
