Located just off the coast of Kefalos in southern Kos, Greece, is the stunning Kastri Islet. This rocky and barren area boasts minimal vegetation, but offers a unique opportunity to explore the remains of an ancient castle that once guarded the bay from enemy attacks and pirates. Visitors can also marvel at the picturesque blue and white church, dedicated to Agios (St.) Nicolas, the patron saint of sailors. Whether reached by boat or by swimming from Kefalos beach, the impressive Kastri Islet is a must-see destination for anyone traveling to Greece.
