The harbor loosens its grip and the Atlantic breathes cool against your cheeks as the dive center skiffs ease away from Sesimbra pier. Below, the sea has a personality—rocky reefs that shelter curious fish and groves of algae that sway like slow traffic. The first minutes are adaptation: breathing through a regulator, trusting the weight of the wetsuit, and letting the ocean’s pulse set the pace.

The harbor loosens its grip and the Atlantic breathes cool against your cheeks as the dive center skiffs ease away from Sesimbra pier. Below, the sea has a personality—rocky reefs that shelter curious fish and groves of algae that sway like slow traffic. The first minutes are adaptation: breathing through a regulator, trusting the weight of the wetsuit, and letting the ocean’s pulse set the pace.
This experience takes place in and around Professor Luíz Saldanha Marine Park, a protected stretch of Portuguese Atlantic known for its rocky outcrops, kelp patches and pockets of biodiversity that contrast with nearby fishing history. Sesimbra itself is a centuries-old fishing town whose maritime culture shapes local attitudes toward the sea; eco-diving programs here grew from that tradition and modern conservation efforts to protect cold‑water reefs and seagrass beds.
Expect clear practical instruction—SSI’s Try Scuba methodology—followed by two shallow guided dives: an adaptation dive to build confidence and an exploration dive that includes a simple beach-clean activity. Nature here is not passive; currents nudge you along channels and octopus dens hide behind ledges. Visibility and temperature vary by season, so plan accordingly.
Practical guidance: arrive hydrated, wear sturdy shoes for the harbor, and be ready to climb a ladder to the skiff. The operator keeps a 1:2 instructor ratio and provides all gear. No full certification is required, but basic swimming ability and a moderate fitness level are recommended. If you’re aiming for both a discovery dive and a tangible conservation action, this mix of training and hands-on cleanup makes for a compact, responsible ocean experience.
No—this is a Try Scuba program (SSI/Wild Sea Europe) designed for beginners; instructors cover all basic skills during the session.
Minimum age policies vary by provider; many Try Scuba programs accept children from about 8–12 years old with parental consent—confirm with the operator when booking.
Summer temperatures commonly range 18–22°C with good visibility; spring and autumn cool to 14–18°C and visibility can vary with swell and runoff.
The operator monitors conditions and will cancel for safety; the booking policy allows full refunds if cancelled at least 24 hours in advance or for bad weather.
Anthia Diving Center operates guided outdoor trips and adventures with an emphasis on safety, stewardship, and memorable experiences.
