We will depart from the Old Port of Castro Marina and head north. A short distance from the harbor, we will find the wonderful Castro caves: Palombara Cave, a refuge for seabirds, with hidden entrances and plays of light reflected on the white and pink walls; Azzurra Cave, so called because of the intense reflections of the sea, which create an almost unreal atmosphere; and Zinzulusa Cave, the most famous and fascinating. The visit inside the caves, with the exception of the Zinzulusa, will be accompanied by explanations from our skippers, who will describe the history and characteristics of each one. The tour will end with a brief stop for a swim in the bay of Castro.
