What is a Poros day trip from Nafplio?
A Poros day trip from Nafplio is a one-day journey from the Argolic Gulf to the Saronic Gulf. The road ends at Galatas, and a short boat ride crosses the strait to Poros. The return drive reaches Nafplio the same day.
Nafplio is the capital of the Argolis regional unit and sits on the Argolic Gulf. Its old town stands largely on a peninsula in the northeast Peloponnese. Poros lies off the eastern shore of the Argolid Peninsula, in the southern Saronic Gulf.
A Poros day trip from Athens runs by ferry or hydrofoil from Piraeus, 58 kilometres to the north. Travellers based in the Argolid reach the strait by road on a Poros day trip from Nafplio. The Argolid route skips the open-sea crossing from Piraeus altogether.
The Poros municipality counted 3,261 residents at the last census, with 2,806 of them in the main town. Galatas, the mainland town across the strait, counted 2,145. Under Venetian rule, from the late 15th to the early 18th century, the town held about 15,000 inhabitants.
Which Poros day trips from Nafplio can you book?
The bookable Poros day trip from Nafplio is a full-day tour of 9 hours with swimming. It combines a walk through Poros town with time in the sea. Hiking, cruise, kayak and cooking tours on the island extend the choice.
The GetYourGuide listing goes by the title Poros Island: Full Day Trip From Nafplio with Swimming. Its plan also sets aside time for the island atmosphere. It suits travellers who prefer an organised Poros day trip from Nafplio to a self-drive day.
- A hiking city tour over three peaks, with fresh lemonade
- A daily swimming cruise to explore the Saronic islands
- A sea kayak trip in the waters of Poros
- A traditional Greek cooking class with an organic lunch
Two of these island tours stay on the water: the swimming cruise and the sea kayak trip. The swimming cruise also takes in other islands of the Saronic Gulf. The hiking city tour and the cooking class keep the day on land.
All four tours run on Poros, so each one also fits a self-drive Poros day trip from Nafplio. Other routes from the same base appear among the day trips from Nafplio.
Which road leads from Nafplio to Galatas?
The road for a Poros day trip from Nafplio runs east across the Argolid Peninsula. It passes Lygourio and the Troezen area before it reaches Galatas on the Saronic coast. Galatas stands opposite the island across the strait.
Galatas lies on the coast between Epidavros and Porto Heli. It marks the end of the drive on a Poros day trip from Nafplio. The town stands on the Peloponnese, yet its local government ties it to Attica.
- Seat of the Troizinia-Methana municipality
- Member of the Islands regional unit
- Part of the Attica region
The Troezen area lies south of Methana on the Argolid Peninsula. Its municipal unit, Troizina, takes in Galatas, Troizina village, Taktikoupoli, Dryopi, Karatzas and Ano Fanari. The unit counted 4,668 residents at the last census. Troizina village stands 23 metres above sea level.
Without a car, the organised tour replaces the drive. KTEL Argolida runs daily buses from Nafplio to regional destinations and to Athens. Rail service to Nafplio was suspended in the 21st century, so the road carries every land journey.
How do you cross the strait from Galatas to Poros?
The sea leg of a Poros day trip from Nafplio crosses the narrow strait at Galatas. The car ferry carries cars and takes 5 minutes, while a water taxi takes 3 minutes. Both link the mainland town with the island.
Self-drive travellers on a Poros day trip from Nafplio leave the car in Galatas to cross on foot. The water taxi is the faster of the two boats. Drivers who want their own vehicle on Poros board the car ferry.
On the island, local buses run from the harbour to Neorio and to Monastiri. A Cyclopolis bike-sharing station with 13 bikes gives a car-free option on a Poros day trip from Nafplio. Poros has no airport, so every visitor arrives by boat.
Henry Miller, the American writer, described the arrival at Poros in his book The Colossus of Maroussi. The Greek writers Giorgos Seferis, Kostis Palamas, Kosmas Politis and Ioulia Dragoumi also wrote about the island.
How long does a Poros day trip from Nafplio take?
An organised Poros day trip from Nafplio lasts 9 hours from start to finish. The boat crossing adds only minutes each way. The rest of the day goes to the drive and the hours on Poros.
The 9 hours cover the drive to Galatas, the crossings, the stay on Poros and the return drive. A self-drive Poros day trip from Nafplio keeps the same stages on the driver’s own clock.
Each tour booked on Poros adds its own block of time to a Poros day trip from Nafplio. Drivers plan the departure from Nafplio around the start time of that tour. The return crossing then fits after the tour ends.
Travellers who finish in Athens instead of Nafplio switch transport at the strait. Hydrofoils and catamarans reach Athens in just over an hour. Ships take 3 hours, and coaches from Galatas take 3 hours as well.
What does the old town of Poros show around the clock tower?
The old town seen on a Poros day trip from Nafplio climbs the hill above the harbour. Neoclassical buildings rise in tiers up the slopes. The clock tower, built in the 20th century, stands at the top as the main landmark.
In the 19th century, envoys of England, France and Russia met Ioannis Kapodistrias on Poros. They met to set the borders of the future Greek state. Kapodistrias, the first head of state, made Nafplio the official capital in the same century. He was later assassinated there, on the steps of Saint Spyridon’s church.
At the edge of town, the Naval Training Centre keeps an old role alive. The first Greek naval base opened on Poros in the 19th century. The main naval work moved to Salamis later that century, but the Hellenic Navy still trains here.
- The Archaeological Museum on Korizis Square
- The Poros Shell Museum in the Chatzopouleios Library
- The museum dedicated to Alexandros Koryzis, a Prime Minister of Greece
- The Bourtzi castle, built in the 19th century by Carl Wilhelm von Heideck
- The ruins of a Russian supply base at the edge of town
The Russian base went up after the Treaty of Kuchuk Kainarji, in the late 18th century. It held coal stores, food stores and a hardtack bakery. Its ruins became protected monuments in the 20th century. They add an older layer to a Poros day trip from Nafplio.
What are Sphairia and Kalavria, the two halves of Poros?
Poros town, the base of a Poros day trip from Nafplio, stands on Sphairia, the volcanic southern half. Kalavria is the larger, wooded northern half. A small bridge over a narrow canal links the two, which cover about 31 square kilometres together.
Sphairia’s volcanic rock dates from the Neogene period. Kalavria carries limestone, sandstone and ophiolites. The island’s central limestone massif holds karst sinkholes and caves with stalactites. Limestone from Poros went into Mycenaean tholos tombs, including the Tomb of Aegisthus at Mycenae.
The last eruption of the Methana volcano, in the 3rd century BC, changed the shape of the island. Under Roman rule, from the 1st century BC to the 4th century AD, Poros paid tribute to Troezen. Methana lies a short way north of Troezen, near the route of a Poros day trip from Nafplio.
The name Kalavria recalls Calauria, a city-state of the Mycenaean period, and the island’s ancient name was Pogon. In the 20th century, the island lived on wheat, vines, olives, livestock, fishing and shipping. Beyond the town, these points widen a Poros day trip from Nafplio:
- Vigla, the highest peak at 358 metres, in the west-central part
- Kavos Vasili, an Early Bronze Age site and the oldest known settlement in the area
- Agios Nektarios and Kyani Akti, the two villages outside Poros town
What remains of the Sanctuary of Poseidon on Poros?
The Sanctuary of Poseidon sits in the northern part of Poros, on Kalavria. Only foundation trenches, roof tiles and parts of a gateway building remain. A Poros day trip from Nafplio reaches the island where Demosthenes died in the 4th century BC.
A Doric temple of Poseidon rose here in the late 6th century BC. It measured 27.4 by 14.4 metres, with six columns across each end. Swedish archaeologists opened the site in the late 19th century, in their first dig in Greece.
The sanctuary served as the centre of the Kalaurian amphictyony, a league of seven cities. The member list names Hermione, Epidaurus, Aegina, Athens, Prasiai, Nauplia and Orchomenos. Nauplia is today’s Nafplio, so a Poros day trip from Nafplio retraces a link within the league.
The orator Demosthenes fled here after Athens condemned him to death. Archias, an agent of the Macedonian general Antipater, tracked him to the sanctuary. Demosthenes took poison from a reed before his capture, aged 62.
What is the Monastery of Zoodochos Pigi on Kalavria?
The Monastery of Zoodochos Pigi is a Greek Orthodox monastery founded in the 18th century. It stands on a pine-covered slope 4 km east of Poros town. A Poros day trip from Nafplio with free time leaves room for the short ride east.
Its name means Life-Giving Spring, a title of the Virgin Mary in Orthodox worship. Old pine forest covers the centre and south of the island around it. In the early 19th century, monks from Mount Athos took refuge here.
The same group of monks later founded a new monastery on the island of Paros. Visitors on a Poros day trip from Nafplio keep upper arms and knees covered inside the monastery.
Which beaches suit a swim on a Poros day trip from Nafplio?
Poros keeps its sandy beaches on the southern shore, plus Vagionia Bay in the north. Kanali lies closest to town, while Askeli is the longest. Picking one shore ahead of the swim stop saves time on a Poros day trip from Nafplio.
- Kanali: the nearest beach to town, just past the canal
- Askeli: the longest beach, with sunbeds and watersports
- Love Bay: a small cove framed by pine forest
- Megalo Neorio: a wide sandy bay west of town, lined with pines
- Russian Bay: a western cove with the ruins of a Russian naval base
Russia gained shipping rights in Ottoman waters in the 18th century. It then ran a supply station at the edge of Poros town. After Greek independence, Governor Capodistrias took that site for the Greek navy and offered a larger cove nearby. Russian ships used the new base through the 19th century.
The ruins at Russian Bay are protected monuments today. Swimmers on a Poros day trip from Nafplio reach the cove by road west of town. A beach-by-beach comparison with Spetses sits in Spetses vs Poros.
What is the lemon forest across the strait at Lemonodasos?
Lemonodasos is a forest of lemon trees on the mainland, about 3 km outside Galatas. It lies at Artimos, on the road toward Porto Heli. A Poros day trip from Nafplio passes through Galatas, the village closest to the grove.
The name joins the Greek words for lemon and forest. The grove is a nationally known attraction, and school groups visit it on excursions. Its old draw was Kardasi, a watermill that ground flour with the force of a waterfall.
The American writer Henry Miller recalled the story of the lemon groves opposite Poros. The grove fits the mainland leg of a Poros day trip from Nafplio, not the island hours.
What does ancient Troezen add on the drive to Galatas?
Troezen was an ancient city on the Argolid Peninsula, south of Methana, where the village of Trizina stands. In myth, Aethra conceived the hero Theseus there. A Poros day trip from Nafplio ends its mainland leg in this same district.
Aethra was the daughter of Pittheus, and she lay with both Aegeus and Poseidon here. Her son Theseus grew up in Troezen before he left for Athens. Galatas served as the seat of the former municipality named after the old city.
Euripides set his tragedy Hippolytus in Troezen. In the play, a bull rises from the sea and wrecks the chariot of Theseus’s son. Local brides once dedicated a lock of hair to Hippolytus before marriage.
Legend placed a spring here where the winged horse Pegasus touched ground. Finds from ancient Troezen sit in the Archaeological Museum of Poros. The museum lies in town, within walking distance for travellers on a Poros day trip from Nafplio.
Which months suit a Poros day trip from Nafplio?
June to September brings the warmest sea to Poros. A Poros day trip from Nafplio in those months gives the swim stop its full value. Late spring and October suit walks to the ruins and the monastery in milder heat.
June holds the longest days of the year, which keeps daylight on the road back. July and August bring the strongest midday sun. The open sanctuary site offers no roof against it, so an early visit suits those weeks.
Cold winter seas turn a Poros day trip from Nafplio toward the ruins and the museum. A second free day in the Argolid suits the Hydra day trip from Nafplio on another date.
What do you wear and bring on a Poros day trip from Nafplio?
Pack swimwear, a towel, sun protection, a hat and water for a Poros day trip from Nafplio. Walking shoes handle the climb to the clock tower. A light scarf covers the upper arms for a visit to the monastery.
- Swimwear worn under clothes, for a fast change at the beach
- A dry bag for a phone and cards on the sand
- Sunglasses against glare off the water
- Long trousers or a wrap skirt for the monastery
A small backpack keeps both hands free on a Poros day trip from Nafplio. Refill the water bottle in Poros town before any walk uphill. A plastic bag holds wet swimwear on the ride back to Nafplio.
