This dive site, Ferrenança, is a natural porous rock bar located directly in front of the port of Mataró, adjacent to the Arbret bar. It offers a straightforward navigation experience along its rocky formations and surrounding posidonia meadows, ideal for leisurely exploration. There is no specific historical background provided for this natural formation, but its proximity to the port suggests it has long been a focal point for local marine life and possibly fishing.
The site is teeming with typical Mediterranean marine life. Divers can expect to encounter a variety of nudibranchs, vibrant schools of fish, elusive moray eels, and lobsters hiding in crevices. The extensive posidonia seagrass beds serve as crucial nurseries and habitats for numerous species, contributing to the rich biodiversity. Occasionally, larger pelagic species like schools of barracuda (referred to as 'shoal of spit') can be observed in the blue.
The best time to visit Ferrenança for diving and freediving is generally during the warmer months, when water temperatures are more comfortable and marine life is highly active. Its shallow to moderate depths make it an excellent choice for beginner divers and freedivers looking to explore a vibrant ecosystem without demanding conditions. Photographers will appreciate the macro opportunities presented by the nudibranchs and small crustaceans, while the rock formations and posidonia offer interesting wide-angle shots.
