Las Terrazas is a rocky Barcelona boat dive for eels and rays.
Las Terrazas is a boat dive off the Barcelona coast that rewards slow, methodical searching over big, fast swimming. The profile is rocky rather than wide-open, with cracks and ledges that make a torch useful and give the dive its character. It suits certified divers who are comfortable with a deeper boat profile and changing sea conditions. Moray eels, conger eels, lobsters, sunfish and rays are the main draw.
