Deep beneath Mexico’s sun-soaked surface lies a hidden world of underwater caves and tunnels. These flooded cave systems, known as cenotes, were sacred to the ancient Maya and now draw cave divers from around the globe.
Their crystal-clear waters hold secrets that have waited thousands of years to be discovered. Let’s dive into some of Mexico’s most spectacular underwater caves, where every swim through these natural cathedrals brings new wonders.
