An Overview of the Experience

This three-hour tour begins at the Diving center Megadive in Sesimbra, a charming coastal town just outside Lisbon. From there, your journey takes you into the waters of the Professor Luiz Saldanha Marine Park, a protected area teeming with marine life. The presence of a marine biologist as your guide transforms this from a simple boat ride into an educational experience, where you’ll learn about the local dolphin species and their environment.

The tour’s core is the dolphin spotting. These animals are known for their playful antics, often seen jumping, splashing, and swimming alongside the boat—something that delights both kids and adults. The guide’s knowledgeable commentary adds layers of context, helping you understand why these creatures behave the way they do.

You’ll also enjoy breathtaking views of the Arrábida Natural Park—a rugged, green backdrop that makes every photo a postcard moment. The coastal scenery here is dramatic, with steep cliffs and hidden coves that you might catch glimpses of during the cruise.

Detailed Breakdown of the Itinerary

The tour starts at Diving center Megadive at 9:45 am, where you’ll meet your guide and gear up. After a brief safety briefing, the boat departs from Porto de Sesimbra, heading toward the protected marine park. The boat cruise itself lasts around 20 minutes before reaching the first scenic stop.

One highlight is the photo stop at CV7Q+XV, where you can take pictures of the dolphins and surrounding coastline. Here, the guide provides insights into the local marine ecosystem, which enhances the experience beyond just watching animals.

The tour also includes a swimming stop at Ribeiro do Cavalo Beach—a wild, less-developed beach perfect for a dip. Many reviews mention the pleasure of jumping into the water here, with one reviewer noting a “little jump in the water at the top” as a memorable part.

Finally, the boat returns to Diving center Megadive, completing your three-hour adventure. Throughout, you’ll have access to snorkeling masks and life jackets, making it easy to enjoy the water safely.
