The humpback whale begins to arrive on the Manzanillo coast in October and the season ends until April.

Humpback whales mate primarily on the surroundings of Isla Socorro.

To observe blue whales you will have to move away from the coast at least 15 km and their sightings are not that frequent.

There are no specific tours, but on any boat trip you book during the season, if you're lucky you'll be able to see some of these enormous cetaceans.
