Introduction to the Experience

This boat tour in Sesimbra presents an excellent way for travelers to see the coastline from a different perspective. While it’s not the most comprehensive tour available, it offers genuine access to some of the region’s most beautiful and less-visited spots. We like that it’s accessible for a variety of travelers—families, couples, or solo adventurers—who want to enjoy nature without the fuss of complicated logistics.

What’s particularly appealing are the crystal-clear waters and the opportunity to swim on deserted beaches like Ribeiro do Cavalo, Baleeira, Inferno, and Cova da Mijona. These beaches aren’t typical tourist hotspots, so you’ll get a more authentic experience of Portugal’s natural coastlines. The tour’s focus on marine ecosystems not only makes for beautiful scenery but also educates visitors about the area’s ecological importance.

One thing to keep in mind: at just three hours, this tour is a snapshot. If you’re craving a full-day or a more in-depth exploration of the Arrábida Natural Park, you might want to pair this with other activities. But for a well-priced, engaging introduction to Sesimbra’s hidden gems, it hits the mark.
