The Cala del Pato is mall, access is quite complicated and it is one of the most dangerous when it comes to swimming as there are large rocks near the shoreline, so it is not recommended to go with children.
Most people access it from the Cala El Frailecillo, but be careful because if the tide comes in you will not be able to get back. Only the most daring go there, which makes it one of the least popular of the Calas de Poniente so it is one of the quietest.
