Agios Sostis Beach is located on the northern part of Mykonos Island, known for its serene and unspoiled natural surroundings, which make it an ideal spot for families and those seeking a peaceful retreat. The beach is named after a nearby church and boasts a mix of sandy and rocky areas, with crystalline waters that are perfect for swimming. It is a nudist-friendly beach and is frequented by young couples. During the summer months, it can become crowded, but outside peak season, it remains a tranquil haven. The beach's scenic beauty and calm atmosphere are highly praised by visitors.
The beach is not as touristy as other Mykonos beaches, offering a more secluded experience, though it lacks nearby stores and extensive amenities. Access to the beach is primarily by car or motorbike, with parking options available, though limited.
Visitors often stay in nearby areas like Mykonos Town or Panormos for easy access to both accommodations and dining options.
