Haliotis Sesimbra

Haliotis Sesimbra runs from Lojas 1 and 2 at the harbour, Porto de Abrigo, as one branch of a six-location Haliotis network that also covers Peniche, Madeira, the Azores and Cabo Verde. The wider network has run since 2004 and has certified more than 15,000 students company-wide, and describes itself as a PADI Career Development Center; this branch's own affiliation is the plainer PADI Dive Center. Base Leader Paulo Freitas, a PADI Master Scuba Diver Trainer and local skipper, and Paulo Guerreiro, a PADI Master Instructor and Tec Deep Instructor, lead a wider team pictured on the branch page.

Trips launch by boat and sell as separate named products, not one general schedule: a Single Dive Trip, a Night Dive Trip, a Freedive Trip, and a dedicated Single Dive Trip to the River Gurara wreck. Courses run the PADI ladder from recreational Scuba Diving through TecRec technical training, Freediving, Snorkelling and First Aid/EFR, and the centre holds PADI's Adopt the Blue conservation recognition.

Changing rooms, hot-water showers, two classrooms, a filling station and a rental fleet of around 50 equipment sets sit behind the harbour storefront, alongside a retail shop and a relaxation terrace for the surface interval.

Reviewers repeatedly name the same instructors across separate accounts spread over several years, among them Tiago, João, Flora, Mariana and Iuri António, and credit them for patient, safety-focused teaching, several specifically for first-time or anxious divers. Facilities such as the hot showers and changing rooms, alongside marine-life sightings including repeated octopus encounters, recur across independent reviews. The overall pattern runs strongly positive but not unanimous: alongside the run of top-tier reviews sits a real minority describing service failures, not complaints about the diving itself, and one older account describes a cancelled dive and a missed pickup at the rescheduled trip, with the refund left unresolved.
