Join a marine biologist in Puerto Vallarta for a 3.5-hour small-group whale watch. Start with a short humpback lecture, then cruise Banderas Bay with a hydrophone, canopy-covered boat, snacks, and guides such as Cynthia, Michael, or Francisco.

“Our whale-watching adventure was absolutely epic! We were lucky enough to witness humpbacks during mating season, and wow, did they put on a show! The males, clearly focused on impressing the female rather than us, dazzled us with playful and dramatic behaviors that were mesmerizing to watch. Adding to the experience was the incredible biologist on board, who filled the trip with fascinating whale facts and answered all our questions. This wasn’t just a tour—it was an unforgettable marine spectacle! If you’re considering it, don’t hesitate—I HIGHLY recommend this tour!”

They put us right in with the whale sharks and kept looking for a cooperative whale shark that we could swim with for 15-20 minutes. Not all whale sharks will stay around and let you swim with them. These guys were knowledgeable and respectful to us and the wildlife! We will book with them again next time!”
