El Cardumen

Centro de Buceo El Cardumen operates from Puerto de la Cruz marina, running PADI certification courses from Open Water through Rescue Diver alongside diving baptisms supervised directly by a PADI professional, in groups the centre markets as deliberately small. A bundled specialty pack pairs Nitrox and deep-diving training. Underwater cameras are welcome on every dive, and photo or video souvenirs are offered specifically for first-timers doing a baptism dive. What sets El Cardumen apart from its Puerto de la Cruz neighbours is a second business under the same brand: tandem paragliding, with 40 to 60 minute flights launching from Izaña, La Corona, Taucho, Mesa del Mar and Punta Hidalgo. No single owner or manager appears in public listings, but one name comes up again and again across reviews spanning years: instructor Rafa, credited repeatedly for a warm welcome and careful, safety-focused guiding.

El Cardumen's two main review platforms disagree sharply. Google runs high, 4.9 out of 5 from 51 reviews, while TripAdvisor's overall figure sits at 3.6 from 56, a notable gap for the same small business. Worth noting: the individual reviews visible on the TripAdvisor page itself lean heavily toward 5 out of 5, which points to a handful of older, lower entries dragging the aggregate down rather than a change in what divers experience today. Where the platforms agree is on Rafa. Reviewers from 2018 through 2026 describe him and the team as professional and attentive, several specifically recalling a big ray, barracudas or a seahorse on their dive, and more than one adding that they'd book again without hesitation.
