We depart from Marina Vallarta around 9:00 AM. Just 10 minutes into the journey, we reach the mouth of the Ameca River, a scenic spot that’s also a great place to spot dolphins enjoying their morning meal. About an hour into the trip, we arrive at the islands. During the winter months, the journey itself becomes part of the adventure, as the ocean often offers incredible wildlife sightings — including dolphins, sea turtles, manta rays, and even whales. Once we reach the islands, we’ll provide you with snorkel gear and life jackets. Our team will guide you on how to properly use the equipment and share tips to improve your in-water skills, ensuring a fun and safe snorkeling experience.
