Main image

Sounio National Park is a protected coastal area in the southern part of the Attica region of Greece, encompassing the promontory of Cape Sounion. The area is noted for its dramatic coastal cliffs, sea views and Mediterranean biotopes.

The park’s shoreline offers walking and viewing opportunities along rocky headlands and beaches; visitors commonly come for scenic views, coastal habitat and access to the archaeological site on Cape Sounion. The landscape is predominantly scrub, rocky shore and pine-covered slopes.

The landform and coastal features developed naturally; the most prominent human-made feature in the vicinity is the ancient Temple of Poseidon on Cape Sounion, which dates to the 5th century BCE. Management of the park focuses on habitat protection, public access and the preservation of archaeological and scenic values.

Sounio National Park sits on the southernmost tip of the Attica peninsula overlooking the Aegean Sea, roughly along the coastal route southeast of central Athens.

  • Temple of Poseidon nearby: The Cape Sounion area is best known for the nearby Temple of Poseidon, which is a frequent reason visitors travel to the park for coastal views and sunset visits.
