Things to Do in the Sea of Cortez

Whether you are searching for deep sea diving or simply trying to relax on the beach, you’ll find no shortage of things to do in the Sea of Cortez. On land, the sea’s thousands of miles of coastline feature hundreds of pristine beaches, hilly landscapes, and other amazing geological features. Beachside retreats, nature hikes, and off-road adventures are all excellent activities to enjoy on the shores of the Sea of Cortez. On the sea itself, sailing, kayaking, and water sports are great choices for those who prefer warm, calm waters. However, when it comes to water activities, snorkeling and scuba diving reign supreme in the Sea of Cortez. That’s because this unique body of water is home to thousands of rare and amazing marine wildlife species. You can learn more about wildlife in the Sea of Cortez in the following section.

 

Wildlife in the Sea of Cortez

Due in large part to its unique climate and geographic features, the Sea of Cortez harbors a rich marine ecosystem as diverse and spectacular as any on Earth. Its placid and protected waters harbor thousands of fish and mammal species, as well as some 5,000 species of micro-invertebrates.  In addition to a wide range of endemic creatures, such as the critically endangered tiny vaquita, the Sea of Cortez also hosts many migratory species, such as the humpback whale, California gray whale, killer whale, manta ray, leatherback sea turtle, and Humboldt squid — as well as the world's largest animal, the blue whale. The Sea of Cortez’s more than 900 islands are important nesting sites for thousands of seabirds, and its rich waters are primary feeding, breeding, and nursing grounds for a plethora of migratory and resident fish species.

 

Travel to the Sea of Cortez – A UNESCO World Heritage Site

The unique ecosystem found in the Sea of Cortez, as well as its overall natural beauty and scientific significance, have earned it special status as a UNESCO World Heritage Site. Protected by both national and international bodies while still being utilized for tourism and commercial ventures, the Sea of Cortez embodies the delicate balance between use and preservation. By visiting its waters, travelers will see firsthand that the Sea of Cortez is both a natural wonder and a testament to human cooperation.
