Only 370 m from Peloponnesian Peninsula explain its popularity, with some good beaches, fair taverna, and considerable nightlife. the island is irregularly sharped, with a convulated coastline with many coves and beaches, and nearly divided into two islands joined by a narrow isthmus. The smaller part, Sferia, contains the port and major city of poros and the biggest concentration of the tourist facilities. Kalavria, the much larger half, is densely wooded with many natural harbours, beaches and secluded villas.

WHAT TO SEE & DO:

Poros town has a Naval Training School and a small Archaeology Museum with finds from ancient Troezen. The island's most famous sight is the Temple of Poseidon, now little more than a few broken columns and some rubble on a hill near the center of Kalavria. most of the marbles was hauled away to build a monastery on Hydra. In 332 B.C. after the defeat of the greek forces by the Macedonians at Lamia, Demosthenes fled to the Temple of poseidon for refuge (for political exiles) but Antipater's forces pursued him, and he committed suicide by swallowing poison hidden in the nib of his pen. 
Those with a special interes in monasteries might want visit the 18th century Monastery of Zoodoches Piyi ("Live-giving Spring"), about 4km southeast of Askeli.
There is a beach northwest of town at Neorio, thought it is not always very clean. Better beaches are found southeast of town at Askeli and Kanali. Instead of touring Poros, you might want to catch the ferry across to Galatas, especially in the middle of June during the annual Flower Festival, when there are parades with floats and marching bands and floral displays. From Galatas you can catch a bus the 8km west to Trizina (ancient Troezen) birthplace of Theseus and scene of the tragedy of his wife Phaedra and son Hippolytus, and the site of an ancient temple of Ascelpios.
