The first stop of the day is in L’Ametlla de Mar, a town on the list of Marine Districts and Villages. Its well-preserved seafaring charm can be seen on a quiet stroll through the lively port and its intimate and varied coves: urban, white sand, rocky, next to lush forests or cobblestones. But today we’re ready for adventure, we pull on a wetsuit for an intriguing activity: swimming among huge specimens of Mediterranean bluefin tuna. We arrive at the pools after a short trip from the coast, during which they give us the basic instructions. It’s a breathtaking experience to see the tuna come out of the deep and swim by us. The activity ends with a tasting of this highly prized fish, which was already used as a source of protein by the Roman legionnaires.
