If you’re thinking about a new way to experience Portugal’s beautiful coastline, this underwater viewing tour in Sesimbra might just be what you’re looking for. We haven’t gone personally, but based on plenty of glowing reviews and detailed info, it’s clear this experience offers a fresh perspective on the area’s natural beauty. For those who love being on the water, want to see marine life up close, or just enjoy a relaxing day out, this tour hits quite a few sweet spots.
What really catches our eye about this experience is the boat’s unique panoramic windows—they let you see beneath the water’s surface without getting wet. Plus, the chance to explore hidden beaches and natural parks makes it stand out from typical boat rides. The price point around $30 per person feels reasonable, given the blend of education, entertainment, and stunning visuals. However, keep in mind that this is a 2-hour trip, so if you’re looking for a full-day adventure, you might want to pair it with other activities.
One consideration is that the experience is weather-dependent. Poor weather could mean cancellations or less optimal visibility, so planning ahead is key. That said, if you’re after an accessible, family-friendly adventure (most travelers can participate), and you’re interested in learning about the local traditions and marine environment, this tour could be perfect. It’s especially suited for curious travelers who appreciate both natural beauty and cultural insights.

The Boat: APNEA with Panoramic Windows
One of the standout features is the boat itself—the APNEA. Its hull is fitted with panoramic windows that look into the water, allowing passengers to see fish, rocks, and other marine life, even without diving or snorkeling. This means you can visit with friends or family who aren’t comfortable in the water but still want to enjoy the underwater sights. The upper platform adds an open-air element, so you get fresh air and stunning views above water as well.
The Itinerary Breakdown
The tour lasts around two hours and includes several stops, each offering something different. The first stop is Praia do Ribeiro do Cavalo, one of Sesimbra’s most celebrated beaches.

Next, the boat visits inaccessible or wild beaches, known for their natural beauty and seclusion. These spots are perfect for relaxing, taking photos, or simply soaking in the scenery. One of these beaches is highly regarded for fishing and diving, so if you’re into underwater activities, it’s a highlight.
Throughout the tour, your local guide—someone familiar with the village and its traditions—will share stories about the local cuisine and fishing culture, adding depth and context to your experience. This personal touch enhances the trip, making it more than just sightseeing.
