Isla Mujeres is not only home to some of the top beaches in the world, but it is also blessed to be one of the destinations with the highest whale shark migrations on the planet. In other places in the world you might have to search for days to spot just one whale shark, whereas in Isla Mujeres you are almost guaranteed to spot multiple whale sharks, ranging from a few to a hundred any given day during season (May-September). These gentle giants migrate near Isla Mujeres once a year where the Gulf of Mexico and the Caribbean Sea meet, following the plankton that they feed on, and if you’re lucky you’ll also get a chance to swim with the giant manta rays that often appear alongside them.
