Barra Fonda is a long coastal bar off Mataró that runs parallel to the shoreline toward Premià. It is a deep, linear Mediterranean dive with porous rock, crevices, and broad depth changes that reward slow exploration. Boat access and depth planning matter more than fish count, especially when winds affect conditions. The draw is the long run, the blue-water feel, and the chance to find octopus, congers, morays, nudibranchs, and other local life.
