Santorini

The island you’re standing on is the collapsed rim of a supervolcano. Let that settle in before you order the wine. The caldera filling the western horizon is not a natural bay; it is a 12-kilometre-wide hole left by one of the most violent eruptions in human history, an event that vaporised an entire civilisation around 1620 BCE and likely sent tsunamis crashing across the eastern Mediterranean. What looks like a serene blue swimming pool from a hotel terrace is, in fact, a crater reaching 385 metres deep with an active volcanic island still breathing steam at its centre. Santorini is a beautiful place, but it is also a geologically violent one, and understanding that gives every cliff-edge sunset, every glass of mineral-tasting white wine, and every ancient wall you walk past a completely different weight.

I flew in from Athens because the 8-hour overnight ferry, however romantic in theory, arrived dishevelled at 5 a.m. at a port with a 580-step staircase to the capital. The high-speed catamaran from Piraeus takes around five hours and starts at about 90 euros, which is the sane choice for most people. The slow Blue Star ferry starts at around 46 euros and suits those who find the swell enjoyable. Either way, once you clear the port of Athinios and drive the hairpin road up the cliff, the island reveals itself in a way that justifies every cliche ever written about it.

The Earthquake Summer Nobody Talks About

In February 2025, Santorini entered a seismic swarm that would eventually record roughly 25,000 to 28,000 individual earthquakes over about eight weeks, fourteen of them above magnitude 5.0. Scientists were candid that the outcome was uncertain. Cruise ships redirected. Summer bookings fell 23 percent compared to 2024. Airlines cut available seats by 26 percent. Hotels reported 20 to 30 percent drops in reservations.

The swarm ended. No significant structural damage occurred to tourist infrastructure, no casualties were reported, and life on the caldera rim returned to normal before peak season. By January 2026 forward bookings had rebounded 19 percent compared to the same period a year before. The point is not that the earthquake swarm was trivial. It is that Santorini sits inside an active volcanic system and always has; the risk never disappears, but the island has absorbed far worse than a February fright and come back the same.

If anything, the swarm accelerated one overdue policy change: Greece finally capped daily cruise ship arrivals at Santorini at 8,000 passengers per day for 2025, with tighter enforcement planned for 2026. A scoring system now evaluates vessel size and operator reliability to determine docking priority. On top of this, a landing levy of 20 euros per passenger applies during the peak June-to-September window. Before these measures, a single day could see 11,000 cruise tourists flood Fira between 10 a.m. and 6 p.m. The cap does not fix overtourism, but it makes the island’s streets navigable for the first time in years.

The Geology Under Your Feet

The black and red sand beaches confuse first-time visitors expecting Cycladic white. The explanation is straightforward once you understand the stratigraphy. Kamari and Perissa on the east coast have beaches of compressed dark volcanic lava, smooth and dramatic. The water there is noticeably warmer than at lighter-sand beaches because basalt absorbs and retains heat. Red Beach, near Akrotiri in the south, is something else entirely. It sits at the base of an eroded cinder cone whose lava was iron-rich; that iron oxidised over millennia, producing the blood-orange and burnt-sienna cliffs that drop directly into the sea. The path to Red Beach has been intermittently closed for rockfall risk, so check conditions before you go. Photography is better from the water on a boat.

The caldera cliffs themselves are a cross-section through 350,000 years of eruptions. You can see the stratified layers as you sail around the rim: white pumice deposits from the Minoan eruption, darker basaltic layers from earlier events, and the reddish oxidised rock at the base. The small island of Nea Kameni at the caldera’s centre is the volcanic system’s current vent and erupted most recently in 1950. Walking on it with a tour group, stepping over sulphur-stained yellow cracks in the rock, is the most honest reminder that this island is not a stage set.

Akrotiri: The Site That Earns Its Own Day

Most visitors treat Akrotiri, the Bronze Age site buried under the Minoan eruption’s ash, as a two-hour add-on to a beach day. That is not enough time and it misses the point. Systematic excavation began in 1967 under the archaeologist Spyridon Marinatos, who had long theorised that a volcanic catastrophe had ended Minoan civilisation. What he found was not scattered ruins but entire city blocks, with multi-storey buildings, intact staircases, running water systems, and walls still bearing their painted plaster frescoes in situ.

The strangest fact about Akrotiri is the absence of bodies. The city was prosperous, with a population of perhaps several thousand, and shows clear signs of earthquake damage preceding the eruption. Yet archaeologists have recovered no human remains in excavated sections. The leading interpretation is that the population read the precursor earthquakes and volcanic emissions as warning, organised themselves, and evacuated. Where they went is unknown. What they left behind: storage vessels, furniture, grinding stones, beds, tools, a civilisation’s domestic furniture frozen in 1620 BCE ash, is on a scale that makes Pompeii look like a footnote.

The frescoes at the National Archaeological Museum in Athens and at Akrotiri itself are better preserved than anything from Knossos, because the ash sealed them rather than letting them decay. The site is covered and climate-controlled, which makes the atmosphere a little clinical but protects what survives. Admission is around 12 euros. Budget at least three hours if you want to absorb what you are actually looking at.

Towns: Where You Stay Changes Everything

Oia: Overhyped and Overpriced, Still Worth an Afternoon

The sunset from Oia’s Byzantine Castle ruins is genuinely good. It is also shared, in August, with approximately 3,000 other people who have been standing in position since 4 p.m. for an 8 p.m. sunset. The crowd is not a small inconvenience; it is a managed public event, with the best wall-top spots claimed hours in advance and tour guides shepherding groups with matching lanyards. The village’s restaurants have largely shed any pretence of value: a caldera-view table, a glass of local Assyrtiko, and a plate of octopus will cost you what a full dinner elsewhere costs, and the service reflects the assumption that you will not return.

None of this means skip Oia. Go mid-morning, before the cruise-ship buses arrive, walk the main lane before the boutiques open their shutters, and look at the blue-domed churches without anyone standing in front of them for a photograph. Leave before 2 p.m. The Ammoudi Fish Tavern below the village, down 300 steps to the small port, is genuinely excellent for fresh grilled fish at prices closer to what grilled fish should cost. The hike down is worth it; the hike back up is less fun.

Caldera-view hotels in Oia start around 800 euros per night at the luxury end (Canaves Oia Suites being the benchmark). The “affordable” caldera-view category begins around 130 to 140 euros and involves rooms where “caldera view” means a lateral glimpse if you lean off your terrace.

Imerovigli: The Same View, Half the Chaos

Two kilometres south of Oia along the caldera path, Imerovigli sits at the highest point on the rim. The views are identical to Oia’s in terms of width and drama. The pedestrian traffic is perhaps 15 percent of Oia’s. The restaurants serve the same Aegean fare at substantially lower prices. Fewer day-trippers reach it because there is no famous Instagram spot to justify the bus ride, which is precisely why it works.

The sunset from Imerovigli is, genuinely, better than from Oia’s castle. Not because the sun falls differently, but because you can see it without elbowing someone out of the frame. Skaros Rock, a twenty-minute moderate hike out along a path from the village, is a detached basalt formation jutting into the caldera with unobstructed westward views in three directions. It was once a Venetian fortress. Now it is one of the most peaceful sunset spots on the island, requiring only the willingness to wear actual footwear and carry water. If you are staying in Oia and want the sunset experience without the mob, take a 15-minute taxi to Imerovigli at 6 p.m. and walk back.

Fira: The Practical Capital

Fira is where the ferry buses drop you, where the banks and pharmacies are, and where most of the island’s backpacker accommodation concentrates. It is louder and more commercial than anywhere else on the caldera, and it is genuinely useful for those reasons. The cable car between the old port and the clifftop town costs 6 euros each way and takes four minutes. It was built in 1979 and is competent, not scenic. The alternative is the 588-step cobbled path that mules and tourists share, which is both an experience and a deterrent.

On the donkeys: skip them, for reasons both ethical and olfactory. The path is steep, narrow, cobbled, and covered in animal waste. The donkeys work long hours in summer heat on harsh terrain, a practice that has drawn repeated criticism from animal welfare organisations. The steps are genuinely climbable for anyone reasonably fit. For those who cannot manage the climb, the cable car exists.

The Archaeological Museum in Fira is small, inexpensive, and worth an hour for its pre-eruption Cycladic ceramics and figurines, which provide context for Akrotiri that the site itself cannot fully supply.

Pyrgos and Megalochori: Where the Island Actually Lives

My honest recommendation for anyone visiting for more than three days: base yourself in Pyrgos or Megalochori, rent a car or ATV, and treat Oia and Fira as day trips. Both inland villages charge roughly a quarter of Oia prices for accommodation of comparable quality. A boutique hotel room in Pyrgos that would cost 400 euros in Oia runs 90 to 120 euros. The streets are real cobblestone lanes with actual residents, cats, and bakeries rather than souvenir shops.

Pyrgos is the island’s highest settlement, built in concentric rings around a Venetian castle at its peak, with 360-degree views across the island to both coasts. You can see the caldera to the west, the eastern beaches to the right, and the ferry port below. Megalochori, slightly southwest, is quieter still, surrounded by vineyards and positioned within walking distance of several of Santorini’s best wineries. Neither village has a sunset cliff, which is, in practice, a relief.

The Wineries

Santorini’s vines are among the strangest-looking in any wine region. Because the Cycladic winds are severe enough to destroy conventional trellising, growers over centuries developed a training system called kouloura: the vine is coiled into a low spiral basket, sometimes only 30 centimetres off the ground, protecting the developing grapes inside the weave. The result looks nothing like a vineyard and everything like an alien crop. Many of the island’s vines are hundreds of years old, never grafted, because the volcanic pumice soil resisted the phylloxera blight that devastated European viticulture in the late nineteenth century.

The flagship grape is Assyrtiko, a white variety with bracing acidity, pronounced minerality, and a saline quality that seems to come directly from the volcanic soil. It does not taste like other Greek whites. At its best, from the oldest kouloura vines, it is genuinely distinctive and age-worthy.

Venetsanos Winery, founded in 1947 and built into a cliff above the port of Athinios near Megalochori, is the more dramatic visit: the tasting room has a vertiginous terrace looking directly down into the caldera. The sunsets from the terrace are excellent and the crowds are manageable. Tasting flights run around 18 to 25 euros.

Santo Wines near Pyrgos is the island’s large cooperative, founded 1947, and the easiest winery to reach by bus. The setting is purpose-built for tourism but the wines are solid and the terrace view is the most photographed sunset backdrop after Oia’s castle. A tasting flight of four wines costs around 16 euros. It is worth doing at least once; it is not worth doing twice.

For a more serious tasting, look up Domaine Sigalas or Hatzidakis (Hatzidakis is a smaller, quieter operation that draws wine-focused visitors rather than tour buses). The Vinsanto dessert wine, made from late-harvested sun-dried grapes, is one of Santorini’s more underrated pleasures and costs far less to taste here than in any European capital.

Getting Around

ATV rental is widely available and costs around 25 to 40 euros per day. It is the best way to reach the beaches, wineries, and Akrotiri independently. The roads are manageable, the island is small (roughly 28 square kilometres), and parking at major sites has improved. Car rental runs 40 to 70 euros per day depending on season. The public bus (KTEL) connects Fira to most major villages and beaches for around 2 euros per journey and is reliable enough for beach days.

A half-day catamaran cruise of the caldera, typically including the hot springs off Nea Kameni, a swim stop at the White Beach, and a basic BBQ with wine, costs around 80 to 160 euros per person depending on group size and what “semi-private” means to the operator. The shared group tours pack more people than the brochure photographs suggest. Book specifically, check the maximum passenger number, and ask whether the hot springs stop is actually a swim or a “view from the boat” stop.

Eating

Metaxi Mas in Exo Gonia is the correct answer to “where should I eat in Santorini” for most meals. It is inland, not on the caldera, seats people on a terrace overlooking an unremarkable village square, and consistently serves the best traditional Santorinian and Cretan cooking on the island. Fava bean puree, courgette fritters, slow-cooked lamb, a grilled fish of the day: mains run 12 to 17 euros. Reservation essential in high season. The owners are in the restaurant. The food tastes as though someone actually cooks it.

Selene in Pyrgos occupies an 18th-century monastery and operates at the other end of the price register entirely. A degustation menu runs 175 to 210 euros per person. Under Michelin-starred chef Ettore Botrini, who took over in 2021, the kitchen works modern Greek fine dining with serious technical competence and a wine list overseen by a Master of Wine. It is excellent for a single special dinner if that is the register you want to visit. It is not a casual meal.

For the Oia harbour, the Ammoudi Fish Tavern at the base of the steps down from the village is honest, fresh, and priced for people who actually came to eat rather than photograph their food. Grilled octopus, whatever fish came in that morning, cold beer, no caldera view, considerably less expensive than anything above on the cliff.

Santorini tomatokeftedes, the island’s small tomato fritters made with the intensely flavoured small tomatoes grown in the volcanic soil, appear on menus everywhere. Order them. They are better here than anywhere else in Greece because the tomatoes are genuinely different, sweeter and more concentrated from growing in low-water volcanic conditions.

When to Go

July and August mean 35-degree heat, ferry queues, 8,000-plus cruise passengers on bad days (the cap helps, but the cap is 8,000), Oia looking like a street festival that nobody planned, and caldera-view room prices at their annual peak. If you enjoy that energy, the island delivers it fully.

May, early June, September, and October offer the same caldera views, cooler temperatures, lighter crowds, lower prices across every category, and the bonus of seeing the island functioning as a place rather than a performance. The shoulder-season light in September is better for photography. Wineries are in harvest mode in September, which has its own appeal. Ferries run less frequently but reliably.

The Fira-to-Oia caldera hike (about 9 kilometres, 3 hours at a comfortable pace) is substantially more enjoyable in May or October than in August when the exposed path becomes a heat trap. Start from Fira early morning, carry two litres of water minimum, and the views across the caldera for those three hours are worth more than any single hotel terrace.

A Practical Note on Booking

The earthquake swarm of early 2025 created temporary confusion in the booking market: some operators refunded deposits, pricing on last-minute caldera-view rooms dropped sharply in March and April of that year, and several hotels quietly offered rates they had not published in years. By summer 2025 those anomalies had corrected. The lesson is simple: Santorini’s premium accommodation sells out earliest in the best locations. Book caldera-view hotels four to six months ahead for July-August. For shoulder season, two to three months is usually sufficient.

One specific booking tip: the villages of Imerovigli and Pyrgos are consistently underpriced relative to the quality of accommodation on offer, and neither requires advance booking as far out as Oia. If you find Oia fully booked or priced beyond your range, either village is a better substitute than a budget room in Fira.
