This is one of the most impressive spectacles that the nature of Holbox has to offer, since this animal has been categorized as the biggest fish on earth; and there are only a few spots on earth where one can observe them.

A boat will pick you up in front of the hotel, very early in the morning since the boat ride will be about 2 hours to the open sea. And then you see them! The enormous fish almost always swim in groups. Apart from just watching them you can swim with them, they are pretty tame. .
