American Crocodiles Adventure & Whale Shark Swim

Xcalak and Chinchorro Atoll (south of Cancun) & Isla Mujeres, Mexico

Have an adventure and visit where few have gone before! The endangered American crocodile is found in the remote and pristine Chinchorro Atoll.


Chinchorro Atoll (Banco Chinchorro Biosphere Reserve) is the best place in the world to get close to American crocodiles. This is a safe encounter with guides who have done years of experimentation and careful planning to make this safe.

In addition to three days of crocodile encounters, we will also have the opportunity to enjoy some diving on excellent reefs in the shallows and some deep walls covered in healthy sponges and large stands of black coral. Sometimes manatees are spotted on these reefs.

Guests can also join us to spend 5 nights on Isla Mujeres in order to experience the whale shark aggregation and maybe jump in with some Giant Mantas. We will have our own chartered boat and go out for full days on the water.

More About this Adventure

Our adventure begins on Isla Mujeres swimming with whale sharks as they feed in a giant aggregation in the Gulf of Mexico. If we are lucky we will also see giant mantas.Read more about the whale shark portion of this trip



The Banco Chinchorro Biosphere Reserve is the largest stand – alone reef in the Northern hemisphere and one of the healthiest. Currently only 1,928 hectares of the 144k hectares are zoned for diving and fewer than one thousand divers get to see these remote and unspoiled dive sites per year. It teems with fish and other sea life, and contains more than 100 shipwrecks as well s the largest and purest population of American crocodiles found in the Americas. XTC Dive Center is our outfitters and guides in Xcalak and was the first operator to organize American crocodile encounters in Chinchorro. They remain the only dive operator with an official concession. They are committed to sustainable tourism and conservation with safety for the wildlife and humans.

On the Chinchorro Banks, we stay in utilitarian fishing shacks over the water on stilts: 36 nautical miles across from Xcalak. (2 -4 hours boat ride). We bring a generator with us so we can charge camera gear and have a little light. We bring all the food and water we will need. There will be 3 sessions with the crocs and the morning dives on the reef. We stay 2 nights at the fishing huts, sleeping in hammocks at night.

Each morning we do dives to hunt lionfish. There is a duo purpose in this – to help eliminate the invasive lionfish population and to get food to attract the crocs.


We dive the beautiful reefs at Chinchorro to enjoy them and gather invasive lionfish to feed to the crocs
The Banco Chinchorro Biosphere has pristine reefs and is a protected marine reserve.

The diving at Xcalak before and after your expedition to Chinchorro is reef diving at its best. A favourite dive is to the daytime resting place for dozens of tarpon. The reefs are full of colorful sponges, soft corals, fish, and we even saw manatees.

My favourite dive at Xcalak had tarpon sleeping in a pack. They were not even fazed by our cameras
While in Xcalak we stay at a beachside resort, home to XTC dive center - our hosts for diving and the croc adventure
You will have an adventure in a place few people have been.


Please Note:

The fishermans’ hunts have no wifi, cell phone, or mobile service. It is a remote shack surrounded by 700 American crocodiles and a few fishermen.


Guests sleep in hammocks and food that is packed out with us is prepared and cooked by our boat captains.


All fishing huts are shared and we sleep in hammocks. A single room is available while we stay in Xcalak at a different hotel: it is an extra $700 per room for the 5 nights.
