Thirasia is the second island of the Santorini caldera, offering stunning views of the volcano and Santorini cliffs without the crowds or high prices. Reached by a short boat ride from Santorini, it provides an authentic, quiet escape with traditional fishing villages and dramatic scenery.
Thirasia sits directly across the caldera from Santorini, sharing the same volcanic origins and dramatic cliffside scenery, yet it exists in a completely different world. Santorini buzzes with millions of visitors each year. Thirasia is home to roughly 300 permanent residents and receives only a trickle of curious day-trippers from Oia.
The island was once part of a single round landmass called Strongili. The catastrophic Minoan eruption around 1600 BC tore it apart, creating the caldera and separating Thirasia as a distinct island on the western rim. Today its clifftop village of Manolas offers views back across the flooded crater toward Fira and Oia. It's the same iconic panorama, seen from the other side, without a single souvenir shop in sight.
Thirasia is a place of donkey paths, abandoned pumice quarries, tiny churches clinging to the cliff face, and evenings so quiet you can hear the sea lapping at the caldera walls hundreds of metres below. There's no nightlife, no resort, and no pretension. Just raw volcanic beauty and the warm hospitality of islanders who still live by farming, fishing, and the rhythms of the seasons.
Thirasia is what Santorini was 50 years ago. The caldera without the crowds, the beauty without the performance.

Expert Recommendation
For the first-time visitor, staying in the main Chora provides the best balance of accessibility and atmosphere.
Thirasia and Santorini were once a single round island called Strongili. The massive Minoan eruption around 1600 BC, one of the largest volcanic events in recorded history, blew the centre apart. It created the caldera and separated Thirasia as a distinct island on the western rim.
In the 19th and early 20th centuries, Thirasia's pumice quarries provided building material exported across the Eastern Mediterranean. The quarries employed hundreds and brought modest wealth. Remnants of the quarrying infrastructure can still be seen along the cliffs.
Archaeological excavations on Thirasia in 1867 by the French geologist Ferdinand Fouqué actually predated the famous Akrotiri dig on Santorini. Fouqué uncovered Minoan-era ruins and pottery, hinting at the civilisation that thrived here before the eruption buried everything under metres of ash.
While Santorini transformed into one of the world's most visited destinations, Thirasia remained a farming and fishing community. Its residents chose not to pursue mass tourism. The island retains a character that Santorini lost decades ago: a living example of what caldera life once looked like.
Explore the heart of Thirasia
Manolas is Thirasia's main village, perched 200 metres above the caldera on the cliff edge. Whitewashed houses with blue doors line narrow lanes, and the views across to Santorini are staggering. The village has a handful of tavernas, a small shop, and the Church of Agios Konstantinos. Getting here from the old port below means climbing roughly 300 steps, or riding a donkey.
Potamos is a tiny agricultural settlement in the island's interior, surrounded by terraced fields, vineyards, and dry-stone walls. Life here has barely changed in generations. The handful of houses are home to farming families who still cultivate tomatoes, capers, and fava beans in the volcanic soil.
A small cluster of houses on the island's higher ground, Kera is home to the Church of Panagia Kerafini, an important local religious site. The settlement is surrounded by wild terrain with views stretching across the open Aegean to the west.
Agrilia occupies the southern tip of the island, a quiet area with scattered houses near the coast. The landscape is stark and volcanic, with cliff formations dropping into the sea. It's one of the most isolated spots on an already isolated island.
Boutique villas, cave hotels, and sea-view suites — all in one place.
The best shores of Thirasia
The main beach at Thirasia's old port, a dark volcanic sand and pebble shore beneath the towering caldera cliffs with a small taverna
Thirasia's current ferry port with a concrete jetty and a small pebble beach area, the first thing you see arriving by ferry
A remote, wild beach on the island's outer (western) coast, with dark sand and volcanic rock formations. Nearly always deserted
Explore every beach and hidden village at your own pace.
Volcanic-soil produce and fresh Aegean seafood in a handful of honest tavernas
Creamy yellow split pea purée grown in Thirasia's volcanic soil, with a sweeter and more intense flavour than mainland varieties. Drizzled with olive oil and capers.
Deep-fried fritters made from sun-dried cherry tomatoes, onion, and mint. A Santorini-region specialty that reaches its purest form on Thirasia.
Fresh octopus hung to dry in the sun then chargrilled, served with olive oil and vinegar. A staple at the waterfront tavernas.
A local variety of white eggplant unique to the caldera islands, typically baked or fried, with a milder and creamier taste than common aubergines.
A fresh, tangy soft cheese made from goat's milk on the island. Spread on bread with tomato or eaten as a meze with local wine.
The sweet dessert wine of the caldera, made from sun-dried Assyrtiko grapes. Thirasia produces tiny quantities of this amber nectar, aged in oak barrels.
From sunrise to sunset in Thirasia
Watch the sun rise behind Santorini from the caldera edge in Manolas. The light gradually illuminates Fira, Oia, and the volcanic islands in the centre of the caldera. You'll witness it in near-total silence.
45 minDescend the roughly 300 stone steps from Manolas down to the old port of Korfos, passing abandoned pumice quarries and cave dwellings carved into the cliff face. Swim at the volcanic beach below, then brave the climb back up. It's steeper than it looks.
1 hourFollow the old donkey paths from Manolas through the island's interior to the farming hamlets of Potamos and Kera. The trail passes vineyards, dry-stone walls, and tiny chapels, with views of the open Aegean.
2.5 hoursHike to the wild outer coast and swim at the secluded beach of Agia Irini, surrounded by volcanic rock formations. Bring water and snacks, as there aren't any facilities. The deep blue water here is exceptional.
2 hoursEnjoy grilled fish, tomatokeftedes, and fava at the small taverna by Korfos beach, sitting beneath the towering caldera cliffs. The freshness and simplicity of the food here is remarkable.
2 hoursWander through the abandoned pumice quarrying sites along the caldera cliff, remnants of the industry that once sustained the island. The industrial ruins set against the volcanic landscape are hauntingly photogenic. It's hard to believe anyone worked here.
1.5 hoursThirasia has dozens of tiny churches and chapels scattered across the landscape, far more than the population needs. Walk between them, each one whitewashed and lovingly maintained, many with panoramic sea views.
1.5 hoursWatch the sunset paint the caldera cliffs of Santorini gold and crimson from Manolas. It's the same Santorini sunset, viewed from the opposite side, shared with perhaps a dozen people instead of thousands.
1 hourDine at one of Manolas's small tavernas as darkness falls over the caldera. The lights of Santorini twinkle across the water, the food is home-cooked and honest, and the silence is extraordinary.
2 hoursSailing trips, sunset cruises, diving, cooking classes and more.
