Beaches and Hidden Spots

The tour stops at some of Sesimbra’s most inaccessible beaches, like Ribeiro do Cavalo, known for its dramatic cliffs and clear waters that are perfect for snorkeling. Unlike beaches that are easily accessible by car or foot, these spots require a boat ride, which enhances the sense of discovery.

From reviews, we know that travelers appreciate the stunning views and the chance to swim in calm waters.

Snorkeling and Marine Life

The snorkeling kit—comprising goggles, tubes, and fins in various sizes—is a thoughtful inclusion, allowing you to make the most of the calm waters. The transparent sea and sandy bottoms make for excellent visibility, perfect for spotting fish and other marine creatures. We loved the way reviewers highlighted the ease of swimming in these conditions and how it added an extra layer of enjoyment to the tour. For many, snorkeling here is a highlight, especially given the chance to observe marine life in their natural habitat.

Comfort and Convenience

The boat itself is a major plus. With a private bathroom onboard, you avoid the hassle of public facilities or rushing back to shore. This small detail elevates the experience, especially for those who might be concerned about comfort or have specific needs. The boat’s capacity keeps the group intimate, fostering a friendly, relaxed environment where everyone can enjoy the scenery without feeling crowded.
