Sesimbra: Sesimbra by Boat – Blue Sea and Hidden Caves

Exploring Sesimbra by Boat: A Closer Look at the Blue Sea and Hidden Caves Experience

If you’re after a taste of Portugal’s coastline beyond the crowded beaches, a boat trip around Sesimbra offers a refreshing glimpse into its lesser-known treasures. This 3-hour voyage with SeaDreams.PT takes you on a journey through crystal-clear waters, revealing secret bays, caves, and beaches nestled within the protected Professor Luiz Saldanha Marine Park. The experience promises not just scenic views but also a chance to swim in deserted beaches and observe the area’s vibrant marine life.

What I particularly like about this tour is how it balances adventure with relaxation. The small group size (limited to 10 participants) ensures a more intimate experience, where guides like José or Sofia can give personalized insights. I also appreciate that the trip is suitable for all ages—perfect for families, couples, or solo travelers craving authentic contact with nature. A second highlight is the opportunity to swim at Ribeiro do Cavalo and other hidden beaches, which are often overlooked by larger, more commercialized trips.

However, a possible consideration is the tour’s duration—just three hours. While this is enough to see some of the key spots and enjoy swimming, it might leave those wanting a deeper exploration wanting more. Also, since the trip doesn’t include hotel pickup or drop-off, you’ll need to organize your own transport to the departure point in Sesimbra, which could be a minor inconvenience depending on your plans.

Despite that, this boat experience offers excellent value for anyone interested in marine biodiversity, scenic landscapes, and a relaxed, small-group atmosphere. It’s a well-rounded taste of the Atlantic coast that’s likely to leave you feeling refreshed and inspired.

The boat pauses at quieter beaches like Baleeira, Inferno, and Cova da Mijona, offering plenty of chances to jump in, relax, and soak up the sun.

Exploring Hidden Caves and Secret Bays

The true charm of the trip is discovering the “secret bays and caves” that are not easily accessible by land. The boat allows you to get close to the cliffs and enter into caves that reveal fascinating rock formations and quiet, deserted beaches. These spots are perfect for those who love nature and want a break from crowded tourist spots.
