There is so much fascinating information about the rich history and ancient cultures of Mexico that it can be easy to overlook the stunning natural beauty that surrounds the country and its importance to the Mexican way of life. Mexico has beautiful mountains, verdant jungles, and dazzling deserts that add to its beauty, but it is the over 9,000 kilometers of coastline that truly make Mexico a paradisiacal playground. Among the bodies of water that border the country, the Sea of Cortez is the most mesmerizing, providing the nation with a wealth of biodiversity and aquatic adventures. Read on to discover 10 interesting facts about the Gulf of California, also known as the Sea of Cortez. 

1. Where is the Sea of Cortez? The body of water separates the Baja California Peninsula from the western coast of Mexico’s mainland.

3. The Gulf of California is about 5 million years old, and it is still considered the youngest sea in the world.

7. Due to its unique ecosystem and oceanographic processes, which have become increasingly useful for important studies, and its natural beauty, the Sea of Cortez was added to the list of UNESCO world Heritage Sites in 2005.

8. Every year the sea hosts a number of migratory species, such as the humpback whale, the California Gray Whale, Leatherback Sea Turtles, and the largest mammal on the planet, the Blue Whale.
