Operated by Cretan Holidays · Athinios Port, Santorini
You step onto the deck at Athinios Port as the Aegean lifts the boat away from the white-cliff shore, the caldera’s vertical face sliding past like a geological map. The sea dares you forward; wind and salt sharpen the colors: bleached domes, ink-blue water, and black lava islands rising like recent memory.
easy.
10 hours.
Suitable for average fitness; requires short uneven hikes on volcanic terrain and boarding small boats.
Departure is at Athinios Port; the boat returns to Athinios and transfers participants to Oia where you stay through sunset.
Yes—the boat approaches Palaia Kameni and allows swimming near the springs, but water can be warm with strong sulphur odor; avoid long immersion if you have sensitive skin.
The trail is short but on loose volcanic rock and steep sections—sturdy shoes and steady footing are recommended; it’s not a technical hike.
Lunch is not included; you’ll have about two hours to eat at seaside tavernas or explore Manolas—bring cash for small establishments.
Santorini’s dramatic caldera is the result of a massive Minoan-era eruption (~1600 BCE); Nea and Palaia Kameni are much younger volcanic formations from repeated eruptions over the past two centuries.
The caldera’s marine ecosystems are sensitive—use reef-safe sunscreen, avoid littering, and stick to marked paths on volcanic islands to protect fragile soils and plants.
