Poros, Greece: The Ultimate Travel Guide to the Saronic’s Twin Island

Last Updated on 7 August 2025 by Johan

Poros is a picturesque pair of islands—Sphairia and Kalaureia—connected by a narrow isthmus and overlooking the Peloponnese coast. With its neoclassical town amphitheatrically built around a hillside clock tower, ancient sanctuaries, lemon groves, and crystal-blue bays, Poros offers a charming, less-touristed alternative to the busy Cyclades.

Geography and Climate

Poros spans roughly 31 km², including the two islets and a slice of the nearby mainland (Kyani Akti). The main town perches on a hillside above Poros Bay, while olive groves and pine forests carpet the surrounding slopes.

The island enjoys a Mediterranean climate, with hot, dry summers (June–September) and mild, wet winters (December–February). April–May and late September–October bring pleasant temperatures (18–25 °C), blooming wildflowers, and calm seas—perfect for hiking and seaside exploration.

Getting There and Getting Around

Poros is one of the most accessible Greek isles:

  • Ferry from Piraeus – High-speed “Flying Dolphin” or conventional ferries sail in about 1 hour.
  • Ferry from Galatas (Peloponnese) – Frequent car and passenger ferries connect over a 200 m strait.
  • Seasonal services from Hydra, Spetses, Aegina, and Agistri.

On the island, you can explore by:

  • Walking – The compact town and beaches are within easy strolling distance.
  • Local buses – Run between Poros Town, Askeli, Neorio, and Love Bay.
  • Car, scooter, or ATV rentals – Ideal for reaching outlying beaches and archaeological sites.
  • Taxi boats – Shuttle between the main town and secluded coves.
