The inner estuary of the Gulf of Guayaquil hosts a native group of bottlenose dolphins. This distinct group has existed separately for millennia from other ordinary bottlenose dolphin settlements found along the Ecuadorian coastline. They have adapted to live in this forceful environment marked by vast tide variations, less salt content, powerful currents, and high-density life.

Your trip leader is a marine biologist who has spent three decades studying this endangered community of dolphins. Tour boats cater to the researcher’s need by serving as data collection points for managing the dolphin population.
