Poros: the complete guide to the Clock Tower, the temple of Poseidon, the Lemon Forest and the beaches

📅 29 October 2026 ⏱️ 10 min read ❤️ Kathy
Poros is the island you see from the Peloponnese as if you could touch it: a strait of two hundred metres separates it from Galatas, and the fast ferry from Piraeus passes through it, in front of the neoclassical houses and the Clock Tower on the hill. It is the easiest island for a day from Athens, an hour away, with pine trees, an ancient temple, a monastery, Russian ruins and, opposite, a forest of thirty thousand lemon trees. Below you will find maps, what to see, the beaches, food, when to go and how to get there.

📍 Where it is

Poros is in the Argosaronic Gulf, between Aegina and Hydra, tucked against the coast of the Peloponnese. From Piraeus the fast ferries arrive in about an hour and the conventional ferries in two and a half. Opposite it, two hundred metres away, is Galatas, which you can also reach by car from Athens, and from there small boats cross to the island every few minutes, day and night.

🗺️ The map of the island

Poros is in fact two islands. Little Sferia, a rock opposite Galatas, has the town, the harbour and the Clock Tower. A bridge joins it to the big Kalavria, covered in pine trees, where the beaches are, Askeli, Neorio and Love Bay, the Monastery of Zoodochos Pigi, the temple of Poseidon in the centre and the Russian Naval Base in the west. A road goes around it, an hour by bicycle or scooter.

🗺️ Map of Poros

Poros is two islands: little Sferia, with the town and the Clock Tower, and big Kalavria, with the pine trees, the beaches, the Monastery and the temple of Poseidon. Opposite, across two hundred metres of sea, are Galatas and the Lemon Forest. Tap each number to see what it is.

⚖️ Is it worth it? The pros and cons

Poros is an island for an easy, green escape close to Athens, not for big sandy beaches and Cycladic lanes. Here is an honest picture.

🕰️ The town and the Clock Tower

The town of Poros is built like an amphitheatre on the rock of Sferia, with neoclassical houses in white, ochre and pink coming down to the quay. At the top, the white Clock Tower of 1927 is the symbol of the island: you climb up by steps through the lanes in ten minutes, and from above you see the strait, Galatas, the mountains of the Peloponnese and the sailing boats coming into the harbour. The harbour is the life of the island: cafés, tavernas, fishing boats, yachts from all over Europe, and the boats from Galatas coming and going.

Poros was the first naval base of the Greek state, from 1828, and the Navy is still here, at the training centre next to Neorio. The small Archaeological Museum on the quay has finds from Kalavria and Troizina. Henry Miller wrote that passing through the strait of Poros was “like sailing through a dream”, and from the deck of the ferry you understand what he meant.

🌅
The Clock Tower in the afternoon

Climb up to the Clock Tower an hour before sunset. The sun goes down behind the mountains of the Peloponnese, the strait turns gold and the lights of Galatas come on opposite. Then go down for an ouzo on the quay.

🏛️ Kalavria: Poseidon, the Monastery and the Russian Naval Base

In the centre of Kalavria, among the pine trees, is what is left of the temple of Poseidon, from the 6th century BC, the sanctuary where the cities of the Amphictyony of Kalavria met. Here in 322 BC Demosthenes, the great orator of Athens, took refuge, hunted by the Macedonians, and drank poison so that they would not catch him. The stones are few, because the people of Hydra took them to build their houses, but the view and the quiet are worth the trip.

On the east coast, the Monastery of Zoodochos Pigi, from the 18th century, is built above a spring, among pine trees and cypresses, with a carved wooden iconostasis and a small beach below. On the west coast, the Russian Naval Base is the ruins of the warehouses the Russians built in 1834 to supply their fleet in the Mediterranean: stone arches among the pine trees, next to a quiet bay.

🍋
The Lemon Forest

Opposite, five minutes by boat from the harbour, Galatas has the Lemon Forest: thirty thousand lemon trees on a slope, with watermills, paths and a taverna at the top, where you drink lemonade from the lemons you see. In spring, when they blossom, the scent reaches Poros.

🏖️ The beaches

The beaches of Poros are small, with coarse sand or pebbles, and all among pine trees. Askeli is the biggest, organised, with hotels, water sports and tavernas. Neorio, west of the town, also has sports and bars, and a little further on Love Bay is a small sandy beach among the pine trees, the most photographed on the island. Kanali, next to the bridge, is the town beach, and the beach of the Monastery is quiet, below the monastery. In the north, Vagionia is a remote bay where, under the water, you can see the foundations of an ancient town.

  • Askeli: the big one, organised, with water sports.
  • Love Bay: small and pretty, among the pine trees.
  • Neorio: near the town, with sports and bars.
  • Kanali: the town beach, next to the bridge.
  • Monastery: quiet, below Zoodochos Pigi.
  • Vagionia: remote, with the ancient town under the water.

🍽️ What to eat

On the quay of Poros eat fish and seafood with a view of the strait, or cross over to Galatas, where the fish tavernas are cheaper. From the Lemon Forest get lemon spoon sweet, liqueur and lemonade, and from the island pine honey. In the evening, the harbour fills with bars and cafés, mainly at weekends.

📅 When to go

Poros is an island for all year round, because it is an hour from Athens and the town never closes. The best time is spring, from April to June, when the lemon trees blossom, and September and October, with a warm sea. In July and August it fills up at weekends, with Athenians and sailing boats. In winter it is a quiet, green day trip.

🗓️ Three days on Poros

Day 1

The town and the Clock Tower

Day 2

Kalavria

By scooter, bicycle or bus: the Monastery of Zoodochos Pigi, the temple of Poseidon among the pine trees, and the Russian Naval Base. A swim at Love Bay or Neorio, and the evening in the bars of the harbour.

Day 3

Across the water

By boat to Galatas, five minutes. A walk through the Lemon Forest, among thousands of lemon trees, and lemonade at the taverna. If you have a car, ancient Troizina, the birthplace of Theseus, is ten minutes away.

Frequently asked questions

Is Poros worth a day trip from Athens?

Yes, it is the easiest island for a day trip: an hour by fast ferry, the town and the Clock Tower on foot, a swim at Kanali or Askeli, fish on the quay and back in the afternoon. If you stay one night, you also have time for Kalavria and the Lemon Forest.

Where should I stay on Poros?

In the town, for the harbour, the restaurants and the view. At Askeli, for a hotel with a beach. At Neorio, for quiet among the pine trees, a few minutes from the town.

Can I come with my own car?

Yes. Either on the conventional ferry from Piraeus or by road to Galatas, from where small ferries take cars across to the island. For Poros alone, though, you do not need it: a bicycle, a scooter and the bus are enough.

How many days do I need?

One day for the town and a swim, two for Kalavria and the Lemon Forest. For longer, combine it with Hydra or Spetses, which are on the same route.
