Hydra: the complete guide to the harbour, the mansions, the trails and car-free swimming

📅 28 October 2026 ⏱️ 7 min read ❤️ Kathy
Hydra is a rocky island in the Saronic Gulf, just over an hour and a half from Piraeus, with no cars. It has a harbour like an amphitheatre, stone mansions built by sea captains, donkeys instead of taxis and swimming off the rocks. Here you will find maps, what to see, where to swim, food, when to go and how to get there.

📍 Where it is

Hydra lies in the Saronic Gulf, opposite the coast of the Peloponnese, between Poros and Spetses. Fast boats from Piraeus take about an hour and a half to two hours, so it is one of the easiest islands for a day trip from Athens.

🗺️ The map of the island

Hydra is long and narrow, with bare mountains. Almost everyone lives in the town, around the harbour on the north coast. On the island there are no cars or scooters, apart from a few municipal vehicles. You get around on foot, by donkey or by water taxi, which takes you to the beaches.

🗺️ Map of Hydra

The town and the harbour are on the north coast. To the west, a path along the sea leads to Kamini and Vlychos, and further on, by boat, is Bisti. The red line shows the coastal walking route. Tap each number to see what it is.

⚖️ Is it worth it? The pros and cons

Hydra is an island for strolling, history and quiet days. It is not an island for big sandy beaches. Here is an honest picture.

⚓ The harbour and the mansions

The harbour is the heart of Hydra, with cafés, tavernas and stone houses climbing the slopes. In the 18th and 19th centuries, the captains of Hydra grew rich from trade and built large mansions. In the War of Independence of 1821, their ships, with admirals such as Andreas Miaoulis, fought at sea.

See the Historical Archives Museum, on the harbour, and the mansion of Lazaros Kountouriotis, which is now a museum. On the harbour there is also the Metropolis monastery with its clock tower, and at each end the old cannons. In the 1960s artists lived here, among them Leonard Cohen.

The Miaoulia

At the end of June, Hydra celebrates the Miaoulia, in honour of Andreas Miaoulis, with events and the burning of a fireship in the harbour.

🥾 Walks and trails

From the town, a path along the sea leads west to Kamini, a small fishing village with tavernas, and then to Vlychos, with beaches. It is an easy walk with lovely views.

For something harder, climb to the Monastery of Profitis Ilias, on the mountain above the town. The climb takes about an hour, and from the top the view reaches the Peloponnese.

🏊 Where to swim

Hydra does not have many beaches, but its water is clean. In the town, at Spilia and Hydronetta, you swim off the rocks. To the west are Vlychos and Plakes, with pebbles, and to the east Mandraki. At the western tip of the island, Bisti and Agios Nikolaos have turquoise water, and you get there by boat from the harbour.

🚤
Water taxis

At the harbour you will find water taxis to all the beaches. In summer, boats also go to the more distant ones, such as Bisti. If you want to come back late, book in advance.

🍽️ What to eat

Hydra is famous for its amygdalota, small pear-shaped almond sweets dusted with icing sugar. In the tavernas of the harbour, Kamini and Vlychos you can eat fresh fish and seafood.

📅 When to go

The best time is from April to June and in September and October: good weather for walking and fewer people. In July and August it is very hot for the steps and prices go up. If you go for a day, pick a weekday.

Frequently asked questions

Can I go for a day?

Yes. With the first fast boat in the morning and the last one in the afternoon, you have enough hours for the harbour, a museum, a walk and a swim.

Where should I stay on Hydra?

In town, near the harbour, so you do not carry suitcases up the steps. In Kamini or Vlychos, for peace by the sea.

How do I carry my luggage?

Porters with donkeys or trolleys wait at the harbour. Many hotels send someone to help you.

How many days do I need?

One day for a first taste. Two to three days to walk, swim and see the island without rushing.
