Cala San Pedro
Cala San Pedro is more easily accessed from Las Negras than Agua Amarga. The 4km-walk from Las Negras takes about an hour; in the summer you can take a taxi launch. This isolated cove is picture-postcard perfect, overlooked by a 16th century castle with tower (built to protect the coast from Berber pirates), and ruined fishing village abandoned after an earthquake. Today inhabitants are a year-round naturist hippy community living in makeshift dwellings with their dogs. You won't find toilets or showers, but there is unofficial camping and a couple of beach bars with limited menus.
