Manolas, Thirasia

The Clifftop Capital.

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.

01 · The island

Discover Thirasia.

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.”

04 · Story

Born from Fire, Shaped by Solitude.

  1. 01

    The Great Eruption

    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.

  2. 02

    Pumice & Prosperity

    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.

  3. 03

    Before Akrotiri

    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.

  4. 04

    Quiet Persistence

    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.

What to Eat on Thirasia.

Volcanic-soil produce and fresh Aegean seafood in a handful of honest tavernas

  1. 01

    Fava

    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.

  2. 02

    Tomatokeftedes

    Deep-fried fritters made from sun-dried cherry tomatoes, onion, and mint. A Santorini-region specialty that reaches its purest form on Thirasia.

  3. 03

    Grilled Octopus

    Fresh octopus hung to dry in the sun then chargrilled, served with olive oil and vinegar. A staple at the waterfront tavernas.

  4. 04

    White Aubergine

    A local variety of white eggplant unique to the caldera islands, typically baked or fried, with a milder and creamier taste than common aubergines.

  5. 05

    Chlorotyri

    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.

  6. 06

    Vinsanto

    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.

07 · A day on the island

Your perfect day.

From sunrise to sunset in Thirasia

  1. 07:00

    Sunrise over the Caldera

    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 min
  2. 08:30

    Climb the Korfos Steps

    Descend 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 hour
  3. 09:30

    Walk to Potamos & Kera

    Follow 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 hours
  4. 10:30

    Swim at Agia Irini Beach

    Hike 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 hours
  5. 13:00

    Lunch at Korfos Taverna

    Enjoy 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 hours
  6. 15:30

    Explore the Pumice Quarries

    Wander 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 hours
  7. 17:00

    Visit Island Churches

    Thirasia 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 hours
  8. 19:00

    Sunset from the Caldera Edge

    Watch 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 hour
  9. 20:30

    Dinner under the Stars

    Dine 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.

FAQ

Thirasia questions.

Everything you need to know about Thirasia

  • Thirasia sits inside Santorini's caldera in the southern Aegean Sea, directly across the water from Oia. It is reached by small ferries and excursion boats from Santorini (Ammoudi, Athinios and the old port), a short crossing of 15 to 40 minutes.
  • Top experiences include climbing the old donkey path from Korfos up to Manolas village, taking in caldera views without the Santorini crowds, swimming off raw volcanic beaches, and eating at a handful of authentic tavernas.
  • Late May to June and September to early October are the best times to visit Thirasia: warm seas, open tavernas and thin crowds. July and August are the hottest and busiest months (and windy when the meltemi blows), while winter is very quiet with many places closed.
  • The easiest way is by local boat from Santorini. Small boats run from Ammoudi Bay (below Oia) taking about 20 minutes, or from the main port of Athinios taking 25 minutes. Some caldera cruise tours also include a Thirasia stop. Direct ferries from Piraeus are infrequent, most travelers transit through Santorini.
  • Yes, but accommodation is very limited. There are a handful of simple rooms and guesthouses in Manolas, and you'll need to book in advance, especially in July and August. Staying overnight is worth it to experience the island's extraordinary evening atmosphere after the day-trippers leave.
  • If you want to experience what the caldera felt like before mass tourism, Thirasia is absolutely worth visiting. The views are equally spectacular, the food is more authentic, and the silence is remarkable. Day-trippers often describe it as the highlight of their Santorini trip.
  • A day trip gives you enough time to climb to Manolas, have lunch, and enjoy the views. But for a deeper experience, one or two nights lets you see the sunset and sunrise from the caldera edge, explore the island's interior, and experience the remarkable quiet of evening on the cliff.
  • There are 3–4 small tavernas in Manolas and one at Korfos beach, all serving simple, excellent food: grilled fish, fava, tomatokeftedes. There's one mini-market in Manolas for basic supplies. There are no souvenir shops, no bars, and no luxury dining. This is part of the island's charm.
