About Agistri

Agistri is a small island in the Saronic Gulf of Greece, administratively part of the Attica region. It is known for a mix of pine-covered hills and coastal beaches and is commonly visited on day trips and short stays from the Athens area.

The island’s low-rise development and wooded interior support walking and cycling, while a handful of small bays and beaches provide swimming and boat access. Accommodations and tavernas are concentrated in the main harbours and a few coastal villages.

Agistri lies southwest of the Attica mainland and close to other Saronic islands such as Aegina; typical access is by short ferry from the port of Piraeus or from neighbouring islands. The island’s proximity to Athens makes it a frequent weekend and day-trip destination.

  • Connections: Regular ferry services connect the island with Piraeus and neighbouring Saronic islands, making it a popular short-break destination for Athens residents and visitors.
