Why visit Santorini

The setting is unlike anywhere else in the Mediterranean. From the caldera rim you look straight down cliffs banded in black, red and cream volcanic rock to deep blue water, with the islands of Nea Kameni, Palea Kameni and Thirasia scattered across the bay.

The island's history is just as layered. The eruption buried a thriving Bronze Age town at Akrotiri so completely that its streets, houses and painted walls survived, earning comparisons with Pompeii.

Then there is the food and wine. Santorini's dry volcanic soil produces small, intensely flavored tomatoes, yellow split peas and capers, and vines trained low into basket shapes to shelter the grapes from wind.

The caldera villages and the rim trail

Oia

Oia stretches along the narrow northern tip of the island, a maze of marble lanes, cave houses, blue-domed churches and old windmills. The main pedestrian street is lined with galleries and shops, but the real draw is the view in every direction.

Ammoudi Bay

Below Oia, a long stairway of about three hundred steps zigzags down to Ammoudi Bay, a tiny harbor of fishing boats and seafood tavernas set against red cliffs. Swimmers follow a rough path around the headland to rocks where people jump into the deep water, and boats leave from nearby for Thirasia.

Fira

The island's capital and transport hub clings to the cliff above the old port. Its lanes are busy with shops, bars and restaurants, and its museums are the best on the island: the Museum of Prehistoric Thera displays wall paintings and finds from Akrotiri, while the Archaeological Museum covers later periods.

Firostefani, Imerovigli and Skaros Rock

North of Fira the rim rises through Firostefani to Imerovigli, the highest of the caldera villages and one of the quietest. From Imerovigli a path descends to Skaros Rock, a headland that once held a fortified medieval town; little remains of the castle, but the walk out is dramatic and the views back along the cliffs are superb.

The Fira to Oia hike

The trail along the caldera rim from Fira to Oia is the best walk on the island, about ten kilometers of paved paths, village lanes and rough volcanic tracks with constant views. Most people take three to five hours. Walking from Fira toward Oia keeps the best scenery ahead of you, and you can catch a bus back.

Ancient sites, inland villages and the south

Excavated Bronze Age streets and multi-story buildings under a modern protective roof at Akrotiri, Santorini, Greece

Akrotiri archaeological site

Near the island's southwestern tip lies one of the most important sites in the Aegean. Akrotiri was a prosperous Bronze Age port town with multi-story buildings, drainage systems and vividly painted walls. It was abandoned before the great eruption and then buried under deep volcanic ash, which preserved it remarkably well.

Red Beach

A short walk from the Akrotiri site, this beach sits beneath towering cliffs of rust-red volcanic rock, with dark sand and pebbles at their base. It is one of the most photographed spots on the island. Allow an hour or two.

Pyrgos and Profitis Ilias

Pyrgos is an inland hill village that grew up around a Venetian castle, with narrow lanes, arched passageways and many small churches climbing to the top. It feels calmer than the caldera villages and has wide views across the island in all directions.

Ancient Thera

On the ridge of Mesa Vouno, high above Kamari and Perissa, lie the ruins of the ancient city of Thera, inhabited from around the ninth century BCE through Roman and early Byzantine times. You can walk its main street past the remains of an agora, a theater, temples and houses, with sweeping views of the sea on both sides.

Emporio, Megalochori and the black sand beaches

The village of Emporio has a well-preserved medieval castle quarter with tight lanes and few shops, while Megalochori is a pretty village of mansions, bell towers and wineries. On the southeast coast, Kamari and Perissa have long beaches of black volcanic sand and pebbles lined with cafes and sun loungers, separated by the great headland of Mesa Vouno.

The volcano and Thirasia

Dark lava fields and a volcanic crater on Nea Kameni with the caldera cliffs behind, Santorini, Greece

Nea Kameni and Palea Kameni

The islands in the middle of the caldera are the volcano's most recent work, built by eruptions over the past two thousand years, the latest in 1950. Boat trips from the old port below Fira land you on Nea Kameni, where a marked trail climbs across black lava fields to a summit crater with small steaming vents and views of the entire caldera.

Thirasia

The second inhabited island of the group is a fragment of the old caldera wall, with a handful of villages and a slow, traditional feel. Boats connect it with Ammoudi Bay and Fira's old port, and many caldera cruises stop at its small harbor for lunch.

Food and local flavors

Start with fava, a smooth puree of the island's yellow split peas served with olive oil, onion and capers.

Wine is the island's great product.

For good-value meals, look beyond the busiest caldera terraces to the inland villages and the beach towns of Kamari and Perissa, where family tavernas serve grilled fish, souvlaki and seasonal vegetables.

Where to stay

Fira is the most practical base, with the bus hub, the widest choice of restaurants and the busiest nightlife.

Firostefani and Imerovigli offer caldera views with more calm, a short walk from Fira.

Oia has the most famous views and many cave-house hotels.

Kamari and Perissa are beach towns with more affordable rooms and easy swimming.

Pyrgos and Megalochori are traditional inland villages close to the wineries, good for travelers with a car who want character and quiet.

Best time to visit

The season runs roughly from around Easter to the end of October.

From November to March many hotels and restaurants close, especially outside Fira, and the weather is cooler and wetter, but it can be a peaceful time to walk and see the island as residents do.

Getting there and getting around

Santorini's airport, near Kamari on the east coast, has frequent flights from Athens taking under an hour, plus seasonal direct flights from many European cities.

The public KTEL bus network is cheap and runs out of Fira to Oia, Kamari, Perissa, Akrotiri, the airport and the port, with frequent service in summer; you usually need to change in Fira to cross the island. Taxis are limited, so book ahead for early flights and ferries.

A suggested itinerary

First day

Explore Fira in the morning, visiting the Museum of Prehistoric Thera, then walk the rim north through Firostefani to Imerovigli and out to Skaros Rock.

Second day

Start early on the trail from Imerovigli to Oia, arriving before the crowds.

Third day

Head south to the Akrotiri archaeological site and the Red Beach viewpoint, then visit a winery near Megalochori for a tasting.

Fourth day

Take a boat trip to Nea Kameni and the hot springs of Palea Kameni, then spend the afternoon on the black sand at Perissa or Kamari, or climb to Ancient Thera if you have energy left.

Practical tips

  • Book accommodation and ferries well ahead for June through September, especially caldera-view rooms.
  • Pack comfortable shoes with grip; marble lanes are slippery and many paths involve long stairways.
  • Carry water, a hat and strong sunscreen, since shade is scarce and the summer sun is fierce.
  • Check cruise ship schedules and plan Fira and Oia visits for early morning or evening on heavy days.
  • Respect private terraces and rooftops; many photogenic spots belong to homes and hotels.
  • Keep some cash for buses, small tavernas and boat tickets, though cards are widely accepted.
