Agios Antonios Beach is a coastal destination on the northern shores of the Lasithi prefecture, in the wider Vlichadia area.

Geographically, it is located east of the area's main settlement and forms part of a coastline with successive bays, positioned immediately after Lagadaki beach.

The landscape is defined by the natural formation of the shore washed by the Cretan Sea, surrounded by a gentle terrain with low vegetation. The area maintains a particularly quiet and pristine character, as it is situated far from major tourist centers and densely populated areas, offering a serene environment for swimmers.

In the wider zone around the beach, residential activity is limited and consists mainly of individual tourist accommodations scattered throughout the area. The lack of intense construction and organized commercial infrastructure directly on the shore enhances the sense of seclusion, making the beach an ideal destination for those seeking contact with nature and the tranquility of the sea.
