About the Beach
Kastri Beach is a remote and strikingly beautiful sandy cove on the northeastern coast of Syros, located near the prehistoric settlement of Chalandriani. It features fine golden sand and clear turquoise water, surrounded by a rugged and wild landscape that provides a sense of total isolation from the modern world. The beach is entirely unorganized and maintains a raw, pristine character, accessible primarily via a challenging hiking trail or by boat from the northern ports. It is a destination for nature lovers and adventurers who want to combine a swim with a visit to one of the most important archaeological sites in the Cyclades. The water is deep and fresh, offering a powerful swimming experience in a quiet and historical setting. There are no facilities or trees for natural shade, so you must be prepared with all your own water and supplies for the journey. The entry into the water is easy and the clarity is consistently high. The atmosphere is quiet and respectful, reflecting the ancient spirit of the land. It is a hidden gem of the northern coastline that offers total freedom.
