Exploring Portugal’s stunning coastline often involves boat trips or snorkeling, but this Seaview Board experience offers a unique way to see marine life with less fuss and more fun. For around $81 per person, you get to lie back on a specially designed board, propelled by fins, and peer through a porthole into the clear waters of Arrabida Natural Park. It’s perfect for those who prefer a relaxed, close-up look at underwater scenes rather than swimming or diving directly.
What I love most about this tour is how accessible it is—no prior experience needed—and how it combines comfort with adventure. The guides, Lukas and Miguel, are praised as the “dream team” by one happy reviewer, making the whole outing friendly and informative. The small group size of just up to 7 people ensures personalized attention, which is great if you’re looking to ask questions or just enjoy a more intimate experience. Plus, the chance to see species like seahorses, seabream, and even a dusky grouper adds a sense of genuine discovery.
However, keep in mind that this experience relies heavily on good weather. Since it’s based around floating on a board and observing underwater through a porthole, rough seas could make it less comfortable or even cancel the activity. If you’re prone to motion sickness or prefer more active or traditional snorkeling, this might not be your first choice. But for a laid-back, scenic adventure, it’s a real winner.

Introduction to the Experience and Its Unique Charm
If you’re like me, the idea of gently floating above the ocean’s secrets sounds pretty appealing. This Seaview Board tour in Sesimbra is a clever twist on marine exploration, appealing especially to those who might find snorkeling or scuba diving intimidating or just prefer a more relaxed approach. Instead of submerging completely, you lie comfortably on a floating board equipped with a viewing porthole, and using fins, you gently propel yourself through the water.
The tour’s highlight is the opportunity to see underwater life up close without getting your face wet or worrying about breathing apparatus. The guides will give a quick rundown before you head out, so even beginners feel confident. The small group size, capped at 7, means you won’t be lost in a crowd, and guides like Lukas and Miguel make a point of sharing their knowledge, turning this into both a fun and educational outing.
What Makes It Special
Two things stand out for me. First, the visual experience is surprisingly immersive—you get to spot fish like striped seabream, seabass, and colorful species such as the golden fish and zebra seabream through that small, clear porthole. One reviewer fondly recalls swimming past caves and rock formations, with guides pointing out the distinct features and marine species. Second, the scenic boat rides across Arrabida Natural Park showcase beautiful landscapes, caves, and beaches like Ribeira do Cavalo, making it a multi-faceted adventure.
A Possible Drawback
The main consideration is the weather. Because the tour involves floating for extended periods, rough seas or high winds could impact comfort or even lead to cancellations. If you’re looking for an adrenaline-filled snorkel or dive, this isn’t it—but if you want a gentle, scenic, and educational outing, it’s perfect. Also, snacks are not included, so bringing water or snacks might be wise if you’re hungry afterward.
Who This Tour Is Perfect For

This experience suits travelers who want a low-impact, family-friendly activity that still offers a glimpse into marine life. It’s ideal if you’re not a confident swimmer but curious about underwater ecosystems. It also appeals to those who enjoy scenic boat rides, caves, and geological formations, combined with a relaxed, guided exploration. Budget-conscious travelers will appreciate the included gear and small-group attention for the price.
Transportation and Timing
You can opt for transfer from Lisbon, making this a convenient day trip. The tour lasts about 2 hours, fitting easily into a morning or afternoon schedule. Booking 28 days in advance suggests it’s popular, and the flexibility to choose specific times or request private groups makes it adaptable for different plans.
Equipment and Safety
All necessary equipment—wetsuit, fins, snorkel, and the innovative seaview board—is provided. This reduces hassle and ensures you’re well-prepared. Guides will brief you on safety, emphasizing that buoyancy is assisted, so even non-swimmers or those with limited swimming ability can enjoy the experience confidently.
Price and Value
At around $81, the tour offers a memorable way to see marine life, especially considering the small-group setting and guided nature. Compared to other activities like snorkeling or diving, this strikes a good balance of affordability and novelty. The inclusion of gear and transfer adds to the overall value, especially for travelers wanting a hassle-free day out.
Who Might Not Love It
If you’re looking for a fast-paced or physically demanding adventure, this might feel slow or too passive. Also, those very sensitive to sea conditions might want to check the weather forecast closely to avoid disappointment.
Why Guides Make a Difference

One of the most praised aspects of this tour is the guides’ enthusiasm and knowledge. “Lukas and Miguel are the dream team,” one review states, highlighting their ability to make marine life understandable and fun. Their presence ensures safety and adds a layer of genuine hospitality that elevates the experience beyond just floating on water.
The Caves and Marine Highlights
The boat ride across Arrabida’s landscape introduces you to caves and tunnels carved by cliffs, which are as impressive above water as the marine life below. The chance to spot species like the dusky grouper or the elusive long-snouted seahorse makes this tour engaging for nature lovers.
Practical Considerations
Booking well in advance (average 28 days) indicates how popular this activity is, likely due to its unique approach and small-group format. The activity ends at the same meeting point, making logistics straightforward. If you’re interested in combining this with other activities in the region—like kayaking, coasteering, or dolphin watching—there are plenty of options nearby.
