There is no airport on the island, so you will have board a ferry from Piraeus port, Athens.
From Athens Airport “Eleftherios Venizelos” to Piraeus Port:
Bus – Just outside arrivals at the airport, take X96 straight from Athens Airport to Piraeus port.
Metro – Athens Airport – Monastiraki, line 3 (blue line).
Monastiraki – Piraeus port, line 1 (green line).
Taxi – Just outside arrivals at the airport.
From Piraeus to Amorgos (Aegiali or Katapola port):
At Piraeus port you will have the chance to buy tickets for the ferry, but it’s recommended to buy your ticket in advance via the internet (for example here). If you’re traveling between the Cycladic islands it’s easier to find tickets but if you travel during the high season we recommend you to book your ticket in advance.
Amorgos has 2 ports. Aegiali is closest to the Askas hotel where we will be staying.
