Discover Portugal’s Sesimbra Marine Reserve with a double scuba experience. Enjoy vibrant underwater life, expert guides, and scenic coastal views for $148.
If you’re looking to add a splash of adventure to your trip in Portugal, a double scuba dive in the Sesimbra Marine Reserve offers an excellent opportunity. This experience promises not just the thrill of exploring underwater but also the chance to witness Portugal’s impressive marine biodiversity right off the coast of a charming fishing village. It’s a well-organized, small-group excursion that balances safety, education, and fun, making it suitable for certified divers and those eager to try diving under supervision.
What we love most about this tour is how it combines the natural beauty of the marine reserve with the picturesque surroundings of Sesimbra itself. Plus, the included boat trip and the chance to explore different underwater sites make the cost of $148 per person quite reasonable—considering the quality of the experience and the professional guidance involved. On the flip side, one thing to keep in mind is that the experience is primarily geared toward certified divers, which might exclude complete beginners unless opting for a supervised “try dive” option.
This tour is perfect for travelers with a passion for marine life, photography enthusiasts, or those simply wanting a memorable, active day near the sea. If you’re comfortable with being in the water and eager to see Portugal’s underwater world firsthand, this adventure should be high on your list.


Looking for more options in Sesimbra? Here are some other experiences worth considering.
Sesimbra, once a humble fishing village, has transformed into a vibrant seaside town while retaining its authentic charm. Its location within the Sesimbra Marine Reserve makes it an ideal spot for those interested in marine biodiversity. As one of Portugal’s biggest protected marine areas, it boasts a wealth of underwater flora and fauna, making each snorkel or scuba outing a different adventure.
What makes this tour particularly appealing is how it leverages the area’s natural assets. The boat trip to the dive sites offers stunning views of the coast—think rugged cliffs, colorful boats bobbing in the harbor, and the shimmering Atlantic. The combination of scenic land and sea provides a well-rounded coastal experience.
The experience kicks off at the local dive center, where you’ll receive a briefing—lasting between 60 to 90 minutes—covering safety instructions, the planned route, and underwater etiquette. This step is crucial, especially in a protected reserve where respecting the environment is paramount.
Once briefed, you’ll head out on a boat to your designated dive site. The vessel’s comfortable and designed for small groups, which enhances the overall vibe and provides plenty of space for gear and socializing. The boat ride itself is often highlighted for its stunning coastal views, setting the scene for the underwater exploration that follows.
Two dives are included in the package, giving you ample time to soak in the sights. The guides are equipped to accommodate your preferences—whether you want to float around snapping photos of vibrant fish, explore rock formations, or even visit wrecks (if available). The focus is on personalizing the experience and ensuring you enjoy what interests you most.
The marine environment here is notably lively. You can expect to see a variety of fish species darting through the water and a rich flora decorating the seabed. From small colorful fish to larger, more curious creatures, the diversity keeps every moment exciting.
One reviewer, Richard, who described the instruction as “good,” also appreciated how the guides made sure the group was comfortable and well-informed. His positive feedback suggests that safety and education are prioritized, which is reassuring for all levels of divers.
The package includes all necessary equipment rental, ensuring you don’t have to bring your own gear. For many, this adds convenience, though you’ll need to bring a dive computer if you use one, as it isn’t included. Also, a torch can be handy if exploring darker spots or wrecks, but again, it’s not provided.
The guides speak multiple languages—English, French, Portuguese, and Spanish—making communication straightforward for international guests. Small group sizes mean more personalized guidance, which is especially helpful if you’re newer to scuba or want some extra attention.
After your dives, there’s plenty of time to relax either on the beach nearby or explore the charming streets of Sesimbra. Many travelers love combining these dives with a walk through the village or enjoying fresh seafood at a local restaurant—perfect for unwinding and digesting the underwater sights.

At $148 per person, the package covers a lot: boat transportation, professional guides, equipment, and two dives. Considering the typical costs of organized dives elsewhere, this is a competitive price point. Plus, the small group setting means you’ll receive better support and a more intimate experience.
The flexibility of booking with a “Reserve now & pay later” option adds to the appeal, especially for travelers planning on a flexible schedule. The full refund policy if canceled 24 hours in advance offers peace of mind.
This experience is ideally suited for certified divers who want to explore Portugal’s marine life without the hassle of planning logistics. If you’re not certified but eager to try, the supervised “try dive” option allows you to experience the ocean with a professional guiding your every move.
It’s also perfect if you appreciate scenic coastal views, small-group attention, and the chance to see an underwater world bustling with life. However, if you’re a complete beginner or prefer to stay dry, snorkeling or other shallow-water activities might be better suited.
The Double Scuba Dive at Sesimbra Marine Reserve offers an exciting and authentic way to experience Portugal’s underwater environment. The combination of vibrant marine life, stunning coastal scenery, and attentive guides makes it a worthwhile addition to any adventurer’s itinerary. It delivers good value, especially for those keen to explore the ocean with a professional at their side.
Travelers who thrive on discovering new underwater scenes, capturing photos, or simply soaking in the natural beauty of Portugal’s coast will find this tour to be a rewarding and memorable experience. It’s an ideal choice for certified divers or those ready to take a supervised leap into the aquatic world.
