Lisbon: Try Dive in Arrábida Marine Reserve Setubal Sesimbra

Introduction: A Unique Underwater Adventure Near Lisbon
This guided scuba experience in the Arrábida Marine Reserve offers a rare chance to see Portugal’s diverse underwater world without prior diving experience. The tour is especially popular for its friendly, certified instructors from top organizations like CMAS and SSI, and its location inside the protected Prof. Luiz Saldanha Marine Park within Arrábida Natural Park. It’s an excellent option for those curious about the sea but unsure about full certification or long commitments.

What I really like about this experience is the careful, patient instruction that makes even absolute beginners feel safe and confident. Second, the stunning environment of reefs and coral gardens teeming with over 1,000 marine species makes it one of the most visually exciting ways to encounter Portugal’s aquatic biodiversity. That said, one potential drawback is the weather dependence—it’s subject to meteorological conditions, which could mean rescheduling if the sea’s not cooperating.

Still, the clarity of the waters, the variety of marine life, and the professionalism of the guides make it a worthwhile adventure for anyone looking to dip their toes (or fins) into scuba diving without the full commitment of a certification course.

A Closer Look at the Experience

How It All Starts: The Safety Briefing and Gear Introduction
Expect a friendly, thorough introduction from your instructor—likely in English, Portuguese, French, or Spanish—who will explain safety procedures and show you the scuba gear. The reviews highlight the calm, patient approach of guides like the woman who managed a stressful first experience with ease. She eased nervous participants by answering all questions and taking her time, which made a big difference for first-time divers.

Learning to Breathe Underwater
The adaptation session is designed to get you comfortable breathing through a regulator, with gentle guidance to help you feel at ease. Many reviews emphasize how this initial step is often the most intimidating, but with professional help, most participants quickly gain confidence. Some reviewers, like Krzysztof, mention how their nerves were quickly eased thanks to helpful and patient instructors, turning what could be a stressful first step into a fun, confidence-building moment.

Guided Reef Exploration
Once you’re comfortable, you’ll descend into the clear waters to explore reefs and coral gardens. Expect to see anemones, gorgónias, lobsters, octopuses, stingrays, sea horses, and sea stars—many of which are endemic or rare. The guides are well-versed about the marine life, so they’ll point out interesting creatures and share insights about this protected ecosystem.

The Marine Park’s Diversity
This area is noted for having the most diverse seabed in Europe, thanks to its geographic position between Serra da Arrábida and Cabo Espichel. The underwater environment is busy with life, and the reef formations create natural habitats that sustain a huge variety of species. These sightings are often described as “close-up” and “on the reef,” making it an immersive experience.

Boat Transfer and Final Moments
After the dive, you’ll return on a speedboat, which adds an extra thrill to the experience. The transfer is included in the price, and the safety support is evident throughout. The entire process—from briefing to boat ride—is smooth and well-organized, as many reviews mention.
