Serra

Drop to the ridge at 18 metres and follow it. Serra runs parallel to El Negre at the height of Pins Mar, forming its own distinct ridge in the Mataro system. The depth sits at 16-20 metres — deep enough for interesting fauna but shallow enough for comfortable bottom times without Nitrox. Work the rock for crevice-dwelling species, then check the open water along the ridge edges where larger fish patrol. Local dive centres describe it as a ridge where the variety of coastal fauna delights photographers looking for both small and large subjects on the same dive.

Serra occupies a middle position in the Barras de Mataro — literally and figuratively. It sits between the shallower ridges and the deeper Pujola, at a depth accessible to all certifications while still offering enough water column for open-water encounters alongside rock-dwelling macro life. The bar has multiple named sections: Blaumar lists El Garbi d'en Serra separately from the main Barreta d'en Serra, suggesting a ridge long enough to offer different diving experiences depending on where the boat anchors. It is not the headline dive off Mataro, but its versatility makes it a reliable option when conditions or group composition call for a mid-depth site that keeps everyone engaged.

Serra is a boat dive from Port Mataro, operated by both Blaumar and Niman Sub. The ridge sits in the same system as El Negre and Pujola, so centres often pair it with another ridge for a two-dive morning depending on weather and group certification levels. At 16-20 metres, bottom time is generous on air — plan for a full hour if your gas management allows. Bring a macro-capable camera if you have one; the site's appeal lies in the combination of close-up rock fauna and the chance to look up into the blue for something bigger passing by.
