Agios Sostis Beach is located on the east coast of Serifos, approximately 5.5 km from Chora. It is known for its picturesque setting and is named after the small chapel of Agios Sostis, which sits on a small peninsula connected to the island by a strip of sand. The beach consists of two coves, one of which is protected from the wind, making it a popular choice for those seeking a tranquil experience. The beach offers fine sand and crystal-clear waters, ideal for swimming and sunbathing. Despite being unorganized, with no facilities available, it remains a favorite among visitors due to its natural beauty and serene atmosphere.
Visitors often appreciate the beach's seclusion and the opportunity to enjoy the sea without the crowds found at more organized beaches. The nearby chapel offers a stunning view of the beach and is a must-visit for its historical and architectural significance. The beach is accessible via a dirt path from a nearby parking area, though caution is advised due to some eroded road points.
Overall, Agios Sostis Beach provides a quintessential Greek island experience with its unspoiled natural beauty and peaceful surroundings.
