What is the Seaview Board Experience?

This tour offers a different way to see underwater compared to snorkeling or scuba diving. Instead of getting into the water with gear, you lie on a see-through board that lets you observe marine life through a porthole while being propelled along the coast. It’s a gentle activity perfect for those who prefer to stay afloat and enjoy underwater views without needing to swim deeply or hold their breath for long periods.

The activity starts at a local partner’s office, conveniently located on Av. dos Náufragos near the TicTic restaurant, and includes a short drive (if opting for pickup) to the scenic spots nearby. The guide, who speaks multiple languages including Dutch, French, English, Portuguese, and Spanish, will give a quick briefing on how to use the board, ensuring everyone feels comfortable before entering the water.

Once in the water, you’ll float and paddle with fins, gliding along the coast where the water is typically clear and inviting. During this time, you’ll have ample opportunities to spot various fish species—such as seabass, seabream, and golden fish—as well as other marine life like the John Dory or even a long-snouted seahorse.

The Itinerary in Detail

The entire experience lasts about two hours, making it a manageable addition to a day of sightseeing around Lisbon or Sesimbra. The trip begins at the meeting point, where the guide provides a quick safety briefing and instructions on how to maneuver the see-through board. From there, it’s a short journey to the chosen swimming spot in Arrabida Natural Park, renowned for its pristine waters and rugged coastline.

Once in the water, you’ll lie on your buoyant board, propelling yourself with fins. The guide, Annabelle, for example, is praised for her patience and clear explanations—she takes the time to show and explain what you’re seeing, enhancing the educational aspect of the tour. Travelers have appreciated her attentiveness, especially as she helps clarify what different fish are and points out lesser-known creatures like the dusky group or the long-snouted seahorse.

Throughout the swim, the focus is on relaxed observation. The transparent boards allow for unobstructed views of the marine environment, which is a highlight for many. Reviewers mention that the water is generally quite clear, making it easier to spot colorful fish and vibrant marine creatures.

The experience ends back at the starting point, with the option of shopping for souvenir photos if you want to remember the trip (note that photos are available for purchase but not included). Snacks and water are provided during the activity, keeping you refreshed after your aquatic adventure.

What Makes This Tour Stand Out?

Unlike traditional snorkeling or scuba diving, the Seaview Board offers a beginner-friendly way to see underwater life without elaborate equipment or training. We loved the simplicity and safety of lying on a buoyant, transparent platform—it’s a perfect middle ground for those curious about marine environments but hesitant about diving.

The guided aspect is another strong point. The fact that the guide, like Annabelle, is knowledgeable and attentive makes all the difference. She not only ensures safety but also enriches the experience with interesting facts about the marine species you encounter. We found that many reviews echo this sentiment, appreciating how guides take the time to explain what’s around us, making the activity both fun and educational.

The cost of $80 per person reflects good value when you consider the equipment, guided commentary, snacks, and the scenic coastal location. It’s particularly attractive for families or small groups, given the limited number of participants (up to 10), which keeps the atmosphere intimate.

We really enjoyed this ride!” Such comments highlight the value of having a personable, attentive guide.

Another insight that travelers appreciated was the ease of use—no prior swimming experience is necessary, thanks to the buoyant design of the board.
