Today Poros consists of two islands: Spheria, which is the modern town of Poros, and Kalaureia, the larger and less populated island. The archaeological site of Kalaureia lies on the island with the same name c. 6 km from Poros town, and can be approached by a winding road either from the town or from the village of Askeli on Kalaureia. The site is on a plateau between the hills of Aghios Elias and Vigla and has a commanding position c. 200 m above the sea level. To the north there is a visual connection with the peninsula of Methana and the islands of Angistri and Aigina, and to the south it is possible to catch glimpses of the sea against the background of the steep Peloponnesian coast. Beyond Aigina, Pireus and the coastline of Attica are visible on clear days.
