The Santorini caldera is not a bay but the flooded mouth of a volcano that erupted around 1600 BCE, collapsing the island's center and leaving a crescent of cliffs that rise 300 metres above the Aegean. The explosion buried Akrotiri under volcanic ash and likely triggered the decline of Minoan civilization on Crete.
Today the caldera floor lies 400 metres below sea level, and the water inside it is sapphire blue, stained by mineral deposits from geothermal vents that still bubble along the submarine ridges.
Nea Kameni, the dark island at the caldera's heart, emerged from the sea in 197 BCE and has erupted twelve times since, most recently in 1950. The crater's slopes are bare of vegetation, covered instead in black and rust-colored lava flows that crunch underfoot. Sulfur vents hiss near the summit, and the rock is warm to the touch. The hike to the rim takes twenty minutes and climbs 130 metres. From the top, the entire caldera spreads out below: Fira's white villages clinging to the cliffs, Oia balanced on the northern tip, and the island of Thirassia forming the western wall.
Most boat tour Santorini departures leave from the Old Port of Fira, accessed by cable car or a 580-step switchback staircase carved into the cliff. Traditional wooden caiques and modern catamarans circle the caldera, stopping at Nea Kameni for the volcano hike and at Palea Kameni, where hot springs mix with seawater in shallow coves. The springs are not pools but open-water zones where iron-rich thermal currents turn the sea a cloudy orange. Swimming here requires jumping from the boat and treading water in the warm plume.
Sunset cruises depart in late afternoon and anchor off Oia to watch the village turn gold as the sun drops into the Aegean. Evening light on the caldera cliffs reveals layers of volcanic strata—black basalt, red scoria, white pumice—deposited over millennia of eruptions. The water in the caldera is deep and clear enough that anchor chains remain visible fifteen metres down. Wind patterns shift quickly here, and afternoon gusts can chop the surface, making morning departures the calmest window for exploration.

A step-by-step walkthrough of Boat Tour Santorini tickets — what you'll see, how long each stage takes, and the details that matter.
You board at the Old Port of Fira, where wooden caiques and sleek catamarans jostle for position along the stone quay. The boat motors out into the caldera, and the cliffs recede behind you, their white villages shrinking to a line of sugar cubes.
Within fifteen minutes you reach Nea Kameni, and the crew ties off to a concrete pier built into the lava. You step onto black volcanic sand that crunches like gravel.
The trail to the crater is wide and dusty, switchbacking up the slope through fields of twisted lava. Sulfur vents appear near the summit, hissing pale yellow steam that smells faintly of rotten eggs. You pause at the rim and look down into the crater bowl, its floor cracked and lifeless. Beyond the crater the caldera stretches out in every direction, impossibly blue.
Back on the boat, you sail to Palea Kameni and anchor offshore. The hot springs are not pools but zones of warm water mixing with the cold Aegean. You jump in and swim toward the orange plume, where the sea temperature jumps ten degrees. Iron deposits stain the rocks rust-red. After twenty minutes you climb back aboard, salt-crusted and warm, and the boat turns toward Oia as the sun begins its descent.
