Santorini: Caldera Sunsets, Cave Hotels & the Aegean in Its Finest Form

Santorini is the product of one of the most violent volcanic eruptions in human history — the Minoan eruption of roughly 1600 BCE, which collapsed the centre of a larger island into the sea, creating the dramatic caldera that now defines the island's entire identity. The result — a crescent of sheer volcanic cliffs rising 300 metres above a flooded volcanic crater, with the towns of Fira and Oia clinging to the rim — is one of the most spectacular natural settings of any inhabited place on earth.

The photographs are accurate. The sunsets are genuinely that colour. The caldera view from a suite carved into the volcanic rock at dusk, with a glass of local Assyrtiko wine, is as good as travel gets.

Where to Stay: The Caldera Rim

Canaves Oia Suites & Spa (canaves.com) in Oia is the standard against which all other Santorini hotels are measured — a collection of 36 suites built into the caldera cliff, each with private plunge pool or terrace facing west over the caldera. The spa, carved 300 metres below the surface into the volcanic rock, and the caldera-view restaurant are both exceptional. Suites from €1,200/night.

Katikies Santorini (katikies.com) in Oia offers a similar category of cave suite experience with three cascading pools tumbling down the cliff face and some of the most dramatic pool photography in the Greek islands. Suites from €900/night.

Grace Santorini (gracehotels.com/santorini) at Imerovigli — the highest point of the caldera rim — sits at the edge of the Skaros rock, the volcanic plug of the island's original Venetian fortress, with 360-degree caldera views and the quieter, more elevated atmosphere of a village that sees far fewer crowds than Oia. Suites from €800/night.

Assyrtiko: Santorini's Volcanic Wine

Santorini produces one of the world's most distinctive white wines — Assyrtiko, grown in basket-trained vines (kouloura) that protect the fruit from the island's strong winds. The volcanic pumice soil, devoid of the phylloxera louse that devastated European vineyards in the 19th century, means some Santorini vines are over 200 years old and ungrafted. The wines are high in natural acidity, mineral, and saline — made for seafood, especially the island's famous fava (yellow split pea purée) and grilled octopus.

Santo Wines Winery (santowines.gr) on the caldera rim at Pyrgos offers the most spectacular wine tasting experience in the Aegean — a terrace overlooking the full caldera panorama, with tastings of Assyrtiko, Nykteri, and Vinsanto (the island's dessert wine). Domaine Sigalas (sigalaswinery.com) at Oia produces the most critically acclaimed expressions of Assyrtiko for those seeking cellar-door depth.

Beyond Oia: The Island's Other Faces

Akrotiri, on Santorini's southern tip, is the site of a Minoan Bronze Age city preserved under volcanic ash — the Greek equivalent of Pompeii, inhabited from 3700 BCE and abandoned before the eruption, leaving a ghost city of multi-storey buildings, sophisticated drainage systems, and extraordinary frescoes now housed in the National Archaeological Museum in Athens. The site (akrotiri.gr) is one of the Aegean's most important archaeological experiences.

Perissa and Perivolos beaches on the island's southeastern coast offer black volcanic sand beaches with clear water and a more relaxed, less photographed atmosphere than the caldera towns.

Getting There

Santorini International Airport Thira (JTR) receives direct summer charter flights from London, Amsterdam, Frankfurt, and Milan. Year-round, the easiest routing is Athens (ATH) on Olympic Air or Aegean Airlines (30 minutes). The ferry from Piraeus takes 7–8 hours on a standard ferry or 4.5–5 hours on a high-speed catamaran — dramatic scenery but slow.
