Santorini is a visual experience unlike any other in the Mediterranean world. This volcanic island—the remnants of a volcano that collapsed during a cataclysmic eruption 3,600 years ago—has a unique geology that translates into an incomparable landscape: black, red and orange lava cliffs plunging sheer from 300 metres into a deep-blue sea; white-and-blue villages clinging to the crater rim as if suspended over the void; and an inner caldera whose wild beauty has no equal in the Mediterranean.
From a superyacht anchored in Santorini’s caldera, facing the multicoloured cliffs and illuminated villages, you enjoy an experience that neither a hotel, nor a villa, nor any other form of accommodation can replicate. It is from the water that Santorini reveals its full spectacular dimension—a truth known to all who have sailed these waters, and one that land-based tourists will never discover.
International Yachts Charter and Brokerage XXIII offers charters in Santorini with our Mediterranean fleet. Our team knows the caldera down to the finest details—the best anchorages depending on the wind, tender access to Oia and Fira, the local wine producers our chef selects for dinners on board facing the cliffs.
The eruption of Santorini around 1600 BC is one of the greatest natural disasters in human history—an explosion estimated at four times the power of the Krakatoa eruption. It destroyed the island’s Minoan civilisation, whose remarkably preserved remains can be seen at Akrotiri, generated a tsunami that devastated the coasts of the entire eastern Mediterranean, and left, in place of a round island, a crescent-shaped archipelago around a submerged caldera.
This caldera—12 kilometres long and 7 wide, with depths reaching up to 400 metres—is today the most spectacular body of water in the entire Mediterranean. Cruising a superyacht in this caldera, surrounded on all sides by multicoloured cliffs, is like sailing in a natural amphitheatre of incomparable geological beauty.
The cliffs of Santorini’s caldera are an open geology book—the different layers of lava built up through successive eruptions over millennia create a spectacular palette of colours. The black basaltic lava of recent eruptions, the white pumice of the Minoan eruption, the red and orange tuffs of intermediate deposits—together they form a natural tableau of geological beauty unique in the Mediterranean.
At the centre of the caldera, two volcanic islets—Nea Kameni and Palea Kameni—form Santorini’s active volcanic cone. Nea Kameni is accessible by boat or from our tender—a hike up to the active crater offers a panoramic view over the entire caldera and an absolutely unique geological experience. The warm hydrothermal springs around Palea Kameni—sulphurous waters at 35°C—are a natural curiosity that our guests often experience by tender from our anchorage in the caldera.
Anchoring in Santorini’s caldera is one of the most spectacular in the world—an experience only a boat can offer. From the hotels and villages perched on the cliffs, the caldera is visible but distant. From the deck of a superyacht anchored 200 metres from the cliffs, immersion is total—the coloured walls surround you on all sides, the illuminated villages reflect in the calm water, and the silence is broken only by the gentle waves against the hull.
The caldera seabed is sandy down to 30–40 metres—perfectly suited to anchoring a superyacht. Average depth is 100 to 150 metres in the centre, but the usual anchoring areas are at perfectly manageable depths.
Our captain pays particular attention to two elements when anchored in the caldera. First, the winds—the caldera can amplify northerly winds. In the event of an established Meltemi, our captain repositions the yacht towards the island’s east coast, which offers better protection. Second, ferry traffic—high-speed vessels linking Santorini to the other Cyclades islands run through the caldera all day. Our captain manages the anchoring position to guarantee safety and comfort on board at all times.
Off the cliffs of Fira — the most central and most spectacular position. Direct view of the village of Fira, its terraces and its stairways descending to the sea. Anchorage 150–200 metres from the cliffs for total immersion in the caldera’s incomparable scenery.
Off Oia — at the northern end of the caldera. The finest position to watch the sunset over Oia from the deck—the cliffs gradually ignite in golden, orange and pink hues before the sun disappears behind the horizon in a unique light show.
Ammoudi — the small fishing port at the foot of Oia’s cliffs. Our tender can dock there directly—it is the starting point for the walk up to Oia via the 200 steps carved into the volcanic rock, a sporty ascent but strikingly beautiful at every landing.
Oia is one of the most photographed villages in the world—its houses carved into the cliff, its iconic blue domes, its lanes dotted with bougainvillea and its spectacular position on the edge of the precipice make it a stop that alone justifies the journey. But it is the sunset over Oia that made it legendary—each evening, hundreds of people gather on terraces and ramparts to witness a natural spectacle of breathtaking beauty.
From your superyacht anchored in the caldera off Oia, you watch this sunset in the best possible conditions—no crowds, no elbow-to-elbow on a packed terrace, just the unobstructed view of the illuminated village and the blazing horizon from your yacht’s deck, a glass of local Assyrtiko wine in hand.
By tender to Ammoudi — the small fishing port lies 200 metres below Oia, at the foot of the cliffs. Our tender docks there directly. From Ammoudi, two options to reach Oia—on foot via the 200 steps carved into the volcanic rock (30 minutes, exceptional views at every landing) or by taxi from the main road.
Lauda — fine-dining restaurant at the top of the cliffs. Exceptional contemporary Greek cuisine, remarkable wine cellar, 180° view over the caldera. Booking several weeks in advance in high season—our chief steward takes care of it well before departure.
Ambrosia — one of Oia’s most respected tables for decades. Creative Mediterranean cuisine, panoramic terrace, Santorini wines with a remarkable selection.
Kastro — ideal position for the sunset. Traditional Greek cuisine, authentic setting, relaxed and unpretentious atmosphere.
Fira is Santorini’s capital—a livelier, more commercial and denser town than Oia, but with an equally spectacular position on the cliffs. Its historic centre concentrates shops, restaurants, bars and museums around lanes that are wider than those of Oia.
Fira’s Museum of Prehistory showcases exceptional objects discovered at the Akrotiri site—frescoes, ceramics, furnishings from the Minoan civilisation frozen by the volcanic eruption. A half-day visit accessible from our tender to Fira’s port.
Fira’s port is accessible by tender from our anchorage. From the port, three options to reach the village atop the cliffs—the cable car (the fastest), the 586 steps carved into the cliff (the most panoramic) or the donkeys (the most picturesque).
Akrotiri is one of the most important archaeological discoveries of the 20th century—an entire city of the Minoan civilisation, frozen under the ash of the 1600 BC volcanic eruption and preserved in a state comparable to Pompeii. The streets, multi-storey houses, furnishings, frescoes—everything has been preserved with extraordinary quality, making it possible to vividly imagine the daily life of this vanished civilisation.
The site is open to the public under a protective shelter. A half-day is needed to explore it properly—our chief steward organises the transfer and guided tour from our anchorage in the island’s southern bay.
Near Akrotiri, Vlychada Beach is one of Santorini’s most original—its white and grey volcanic-ash cliffs sculpted by erosion create spectacular geological formations. Our tender can dock there directly for a swim in a unique lunar setting.
Santorini Assyrtiko is one of the great white wines of the Mediterranean. Grown on vines trained into a spiral basket shape—the “kouloura”—to withstand the violent Meltemi winds, rooted in volcanic soils that give it incomparable minerality and acidity, it produces wines of remarkable complexity and longevity that consistently surprise even the most demanding wine lovers.
The emblematic Santorini estates our chef selects for dinners on board: Domaine Sigalas and its Assyrtiko “Kavalieros”, biodynamic Domaine Hatzidakis, Gaia Wines and its “Thalassitis” served in the world’s finest restaurants. Our chef embarks a carefully curated selection of Santorini wines for dinners on board in the caldera—pairing the finest volcanic landscapes with wines produced from that very soil is a unique gastronomic experience.
Thirassia is Santorini’s sister island—the north-western part of the former volcanic island, separated by the eruption. Far less visited, with only 250 permanent residents, it offers an authentic, preserved Greece just 20 minutes’ cruising from Santorini’s caldera. Its hilltop village of Manolas offers a view over the caldera as beautiful as Fira’s or Oia’s—but without the crowds.
Ios is a 40-minute cruise south of Santorini—an island known for its nightlife and spectacular beaches. A day or evening stop from Santorini perfectly complements a Cyclades itinerary for groups who wish to alternate calm and lively atmospheres.
Folegandros is 45 minutes from Santorini—one of the most discreet and most authentic islands in the Cyclades. Its limestone cliffs dropping into turquoise water, its hilltop village of Chora and its atmosphere preserved from mass tourism make it the ideal stop for a calm interlude after the intensity of Santorini.
May–June — our top recommendation. Water at 20–22°C, island lightly visited, exceptional light, Meltemi still weak. Oia’s sunsets are already spectacular and restaurant terraces are accessible without hours of waiting.
July–August — peak high season. Santorini is at maximum crowd levels—Oia is packed at sunset, restaurants are booked weeks in advance. The experience remains extraordinary, but logistics require rigorous preparation. Booking 4 to 5 months in advance is mandatory.
September–October — the luxury alternative. Santorini regains relative calm, the water remains at 24–25°C in September, and the autumn light has incomparable photographic quality. Our second recommendation after June.
Yes—the seabed is sandy, perfectly suited to anchoring. Our captain monitors winds and ferry traffic at all times. In the event of Meltemi, he repositions to the sheltered east coast.
It is even the best way to watch it. From the deck of your superyacht anchored off Oia, you have a panoramic view with no crowds and no elbow-to-elbow.
Our tender docks at Ammoudi port at the foot of Oia’s cliffs. Walk up (30 min) or take a taxi. Our chief steward books the tables in advance.
Yes—Mykonos and Santorini are a 2h30 cruise apart. A typical itinerary devotes 3 nights to Santorini and 2 nights to Mykonos over 7 days.
Our chef systematically embarks a selection of local Assyrtiko for dinners in the caldera—one of the most memorable food-and-wine-and-landscape pairings in the entire Mediterranean.
June and September are our recommendations—Santorini regains relative calm, the water is ideal, and the light is of superior photographic quality compared with high season.
