Some people considere this Cartagena cove among the five most beautiful coves in Spain country and the truth is that it was awarded as the Second most beautiful cove of Spain, reader's choice, by the luxury travel magazine Condé Nast Traveler. In top of that, is also a somehow particular cove, since it's surrounded by civil war bunkers and has a big underwater demagnetizer pinnacles field.
The truth is that underwater is not the most interesting cove to dive in but during Spanish Civil War, submarines and ships went trough these waters to reach the Cartagena port and to prevent explosions in the port, they had a demagnetizer pinnacles field situated at some hundreds meters before port.
These large structures called pinnacles were used by submarines and ships to demagnetize their hulls as they passed by and thus release sticky bombs that might be attached to them.
On the seabed there are many thick ropes and you can see, protruding from the bottom, some metal parts that it's better not to remove or touch, just in case.
The experience of imagining the submarines and sticky bombs on their hulls while doing this dive it was like transporting you to another period of History.
