The 2-hour cruise is designed to get you as close as possible to pods of dolphins, which often approach the boat out of curiosity. Depending on the weather and dolphin activity, you may see dozens of them swimming together, leaping into the air, or riding the waves created by the boat.
Even in rainy weather, tours usually operate as scheduled, and sightings remain common. Passengers are encouraged to bring cameras or smartphones to capture the experience, but please secure your devices carefully due to wind and sea spray.

“It was a wonderful experience, even though it was raining! The staff were so accommodating, and we got to see so many dolphins. Easy to find and well-organized.”
“Saw 40 to 50 dolphins! The cruise was smooth and scenic. If you’re sensitive to motion, take precautions—it’s about 40 minutes each way. Still, a great experience!”
“Very friendly staff and informative explanations about the dolphins. They even waited for us when we were running late due to traffic. Highly recommended!”
