My family and I just returned from a trip to Isla Mujeres. We timed this trip around the full moon in July because of the bonita spawning that attracts large numbers of whale sharks to the area. We had four days of snorkeling -- two days we only found two whale sharks each day, one day we found nothing, but on the last day we hit the "mother load". We had bright sunny skies, flat seas, and hundreds (I am NOT exaggerating) of whale sharks feeding at the surface. Truly a magical experience! Below are a few photos. Others can be found here:
