Are there restaurants on Thirassia?

Several tavernas in Manolas and a couple at Korfos, serving fresh fish well below caldera rim prices.

Thirassia Santorini: The Island Across the Caldera

Thirassia Santorini is the island you have been looking at all week without knowing its name. It is the long dark shape across the water from Oia and Imerovigli, the western wall of the same volcano, separated from the main island by the eruption that made the caldera. Around three hundred people live on it, there is one bus, and almost nobody who comes to Santorini ever sets foot there. That is precisely why it is worth a day. Our Santorini Tours and the boat trips we recommend both reach it.

What Thirassia offers is not a sight. It is the experience of standing on a clifftop terrace, eating fish that arrived that morning, and looking back at the most photographed island in Greece from the outside, with nobody around you. For anyone who has found Oia at sunset overwhelming, this is the antidote.

The Short Answer

Thirassia is a twenty minute boat ride across the caldera, and most visitors reach it on the volcano and hot springs excursion.

The village is Manolas, on the clifftop, up 250 steps from the old harbour at Korfos.

There is very little there, and that is the point: a handful of tavernas, a few streets, cats, and the view.

Most tours give you an hour, which is enough for the climb and a drink and not enough for the island.

To do it properly, take the local ferry and give it a full day.

The Caldera You Would Be Crossing

What Is on Thirassia Santorini

Place	What	Where	Why go	Catch
Manolas	The main village	On the clifftop, 250 steps above the port	Tavernas with the best view of Santorini	Steep, and worth every step
Korfos	The old harbour	Where the small boats land	A few tavernas at the waterline	Almost everything else is above it
Potamos	Inland village	Cave houses in a shallow valley	Genuinely lived in	Very quiet
Agia Irini	Small settlement	Near the newer port	Church and a handful of houses	Little to do
Riva	The new port	Where car ferries dock	Road access to the villages	Not scenic

Beaches	Scattered	Dark sand and pebble, mostly empty	No facilities to speak of	Bring water
Agios Konstantinos	South	Old fishing settlement	Quiet, ruined, atmospheric	Requires transport

Eight entries for a whole island, and that is an honest inventory. Thirassia Santorini is not somewhere you tick things off; it is somewhere you sit still for an afternoon.

How to Get to Thirassia Santorini

On a volcano and hot springs cruise. The most common way. Most full-day excursions from the old port below Fira call at Thirassia Santorini after Nea Kameni and the springs, giving you around an hour ashore. See our volcano tour guide.

On the local ferry. A small boat runs between Ammoudi, below Oia, and Riva or Korfos, primarily for residents. Cheap, infrequent, and the only way to give the island a full day.

By private boat or charter. Flexible and the most comfortable option, and the way to arrive early enough to have Manolas to yourself.

Sailing and catamaran trips frequently anchor off Thirassia for a swim without landing.

Crossing time. Roughly twenty minutes from Ammoudi, longer from Fira’s old port.

Timetables change by season and by weather, so check the day before rather than the week before.

In winter the service is genuinely a lifeline for residents rather than a tourist route, and worth treating as such.

Manolas and the 250 Steps

The climb. From Korfos harbour a zigzag stair of roughly 250 steps rises to Manolas on the clifftop. It takes fifteen to twenty-five minutes at a normal pace.

Donkeys. Available, and we would ask you not to use them, for the same reasons we set out about the donkeys on Santorini.

The road. If you land at Riva instead, a road reaches the village and there is a bus and a few taxis.

At the top. A single main street, a church, a school, a handful of tavernas and terraces looking straight across at Santorini’s rim.

The view. This is the reason to come. From Manolas you see Fira, Firostefani, Imerovigli and Oia strung along the opposite cliff, with the volcano islets in the middle of the water between you.

Lunch. Fresh fish, tomato fritters and local wine at prices that would seem impossible on the other side. The tavernas of Thirassia Santorini are, for our money, the best value meal in the caldera.

Making a Full Day of Thirassia Santorini

Morning boat from Ammoudi. Arrive before the excursion boats and have the village quiet.

Walk up to Manolas, then out along the ridge towards the Kera monastery for the wider view.

Potamos, inland, is a shallow valley of cave houses, mostly abandoned and slowly being restored.

Swim at one of the small beaches, which have no facilities and no people.

A long lunch on a terrace in Manolas, which is the whole point of the day.

Afternoon boat back, ideally timed to reach Oia for sunset from the other direction.

What to bring. Water, sun protection, shoes for the steps and cash, because cards are not universally accepted on Thirassia Santorini.

Why Thirassia Santorini Is a Separate Island

One volcano, three pieces. Santorini, Thirassia and the tiny islet of Aspronisi are the surviving rim of a single volcanic cone that collapsed in the Minoan eruption around 1600 BC.

The water between them is the flooded crater, several hundred metres deep in places.

Nea Kameni and Palea Kameni, the black islets in the middle, are much younger and still active, and they are what the boat trips visit before landing here.

Thirassia was cut off by a later eruption in the third century BC and has been a separate island since.

Excavations here in the 1860s, during quarrying for the Suez Canal, found the first Bronze Age remains in the group and led directly to the discovery of Akrotiri. Our Akrotiri guide covers what came of that.

Why the population left. Farming was hard, tourism went to the other side of the water, and residents moved across or abroad. Thirassia Santorini is what the whole caldera looked like before the hotels.

What It Is Not

Worth being clear, because expectations are half the experience.

Not a resort. There are a few rooms and no hotels of any size.

Not a beach destination. The beaches are dark, small and without facilities.

Not a sightseeing island. There is no museum, no site, no attraction with a ticket office.

Not busy. Even in August it is quiet outside the hour when the excursion boats land.

Not effortless. The 250 steps are real, and there is no shade on them.

What it is. One village, one extraordinary view, several good tavernas, and the calmest hours available anywhere in the caldera.

Who Should Visit Thirassia Santorini

Anyone tired of the crowds. The strongest reason of all.

Photographers. The view of Santorini’s rim from the west is the shot nobody else brings home.

Walkers. The ridge paths are quiet and the whole island can be crossed on foot. See our hiking guide.

Food travellers. The tavernas of Thirassia Santorini serve better fish at lower prices than the caldera rim.

Second-time visitors. If you have already done Oia, Akrotiri and the wineries, this is the obvious next day.

Not ideal for. Anyone with mobility limits, because of the steps and the lack of transport, and anyone who needs a full programme of things to do.

How long to stay? An hour on a cruise, or a full day if your schedule allows it.

Busy? Only in the hour the excursion boats land, and almost entirely empty on Thirassia Santorini for the rest of the day.

A Day on Thirassia, Hour by Hour

09:30. Transfer down to Ammoudi below Oia, which is three hundred steps or a short drive from the village.

10:00. The local boat across. Twenty minutes, with the caldera wall rising on both sides.

10:30. Land at Korfos and start up the steps to Manolas before the day heats up.

11:00. The village. One street, a church, and terraces looking straight back at Santorini’s rim.

12:00. Walk out along the ridge towards the Kera monastery, or down into Potamos and its cave houses.

13:30. Lunch on a terrace in Manolas. This is the reason people who know Thirassia Santorini keep going back.

15:30. A swim from one of the small beaches, or a slow walk back down the steps.

17:00. The boat back, arriving at Ammoudi in time to climb up for sunset in Oia from the opposite direction.

That day costs a fraction of a caldera excursion and is, for many of our guests, the one they remember.

Practical Tips

Check the boat times the day before, because they change with the season and the weather.

Go early. The excursion boats land around midday and leave again within the hour.

Take cash. There is no reliable card acceptance and no bank.

Carry water. There are no shops outside the villages.

Wear real shoes. The steps are uneven and the paths are volcanic gravel.

Watch the wind. A strong meltemi can stop the small boats entirely, which is worth knowing before you plan a day around Thirassia Santorini. Our weather guide covers the pattern.

Do not rely on a taxi at either end of the crossing.

What to Eat There

Fresh fish, landed that morning at Korfos and cooked simply. This is the single best reason to time a Thirassia Santorini visit around lunch.

Tomatokeftedes, the local tomato fritters, made with the small intense Santorini tomato grown on both sides of the caldera.

Fava, the yellow split pea puree that is a protected product of these islands.

Capers and caper leaves, which grow wild on the cliffs.

White aubergine, another local variety, sweeter than the purple kind.

Local wine, often from the family that owns the taverna.

What it costs. Considerably less than the same meal on the caldera rim, which surprises everyone who makes the crossing.

The Short Version

Cross from Ammoudi on the local boat rather than the excursion, climb the 250 steps to Manolas before midday, eat fish on a terrace looking back at Santorini, and take the late afternoon boat home.

Thirassia Santorini has no sights, no beaches worth the name and nothing to book. It has the calmest hours in the caldera and the best view of the island you came to see, and for a great many visitors that turns out to be the day they talk about afterwards.

When to Go

May, June and September are the best months for Thirassia Santorini: calm water, open tavernas and comfortable walking on the steps.

July and August work, and the meltemi occasionally stops the small boats. Go early in the day.

April and October are quiet and lovely, with fewer sailings.

Winter reduces the crossing to a residents’ service, and most tavernas close.

Time of day matters more than the month. Land before the excursion boats and the island is yours; land with them and you share one street with two hundred people for an hour.
