You step down the cable car into a pocket of sea and rock—Fira’s old port yawns beneath sheer cliffs and the boat waits, white against the dark caldera. The hull noses out into the Aegean; the cliffs shrink, the caldera widens, and the salt wind carries a faint sulfur breath that hints at the island’s volcanic past.

Suitable for most fitness levels but requires ability to climb short, rocky trails and swim to the hot springs if participating
The tour lasts about six hours and typically stops at Nea Kameni (volcano), Palea Kameni (hot springs) and Thirassia, with boarding from Fira’s old port or Athinios if transfers are included.
Yes—there is usually a small on-site fee (around €5) for the guided walk to the volcanic ridge, paid to local guides or site staff.
You must be a competent swimmer; the boat anchors roughly 20–30 meters from the shallow spring areas and you’ll enter open water. Follow crew instructions and use provided life jackets if recommended.
No—lunch on Thirassia is at your own expense; bringing snacks and water is advised if you prefer not to buy food ashore.
The Santorini caldera formed after a massive Bronze Age eruption; subsequent eruptions built Nea and Palea Kameni and reshaped local settlement, influencing Aegean trade and culture.
The volcanic islets are fragile—stick to established paths, don’t take rocks or shells and pack out all trash; operators often limit landing areas to protect soil and vegetation.
