Unisub

C/ Platja 8 sits a short walk from the port in L'Estartit. Unisub has been there since 1965, which makes it the oldest dive operation on this stretch of the Costa Brava. Tony Murray founded it. Sean runs it now, with a crew that reviewers call out by name: Roig and Bruce on instruction, Willy on the boat.

The operation is built for throughput. Two boats run up to four trips a day during peak season, covering both the Illes Medes marine reserve and the Montgrí coast. The Tritón alone carries 48 divers. That scale comes with infrastructure most smaller centres lack: three air compressors, a Nitrox station, a repair shop for regulators and BCDs, and a restaurant with a terrace facing the Medes Islands.

Courses run the full PADI range from try dives through Divemaster, plus specialties including Adaptive Support Diver and GROUPER. The equipment fleet is Cressi. Seven languages are spoken. For divers planning a week-long stay, the volume pricing structure is the clearest draw: a 12-dive pack brings the per-dive cost below 35 EUR, about half the single-dive rate.

Repeat visitors set the tone. Reviewers describe a family atmosphere and name individual staff members across multiple years of visits. Instructors Roig and Bruce draw specific praise for course delivery. Boat master Willy gets mentioned for keeping things relaxed on deck.

Beginners report a patient, one-to-one approach that put nervous first-timers at ease. Multilingual capability matters here: French-speaking staff handle Francophone clients, and the centre operates in seven languages overall.

The volume pricing earns appreciation from divers staying more than a few days. A handful of reviews note that snorkelling trips felt shorter than expected, with less than 45 minutes of actual water time. Visibility at the Medes Islands varies by day and season, which some visitors found disappointing.
