About This Tour
Santorini is a caldera — the flooded mouth of one of the largest volcanic eruptions in human history. The cliffs you photograph from Fira, the black sand of Perissa, the white houses of Oia: all of it is the rim and debris of that eruption.
The Santorini volcano tour takes you across the caldera to Nea Kameni, the young, still-active volcanic island at its centre. You hike to the crater with a licensed guide, then swim in the iron-rich thermal waters of Palea Kameni.
We run small groups, traditional wooden boats, and guides who actually live here. No coach-park scale, no scripted commentary.
Getting to the Old Port
By cable car (€4/adult each way, every 20 min in season), by the famous 600 steps on foot (20–30 min), or by donkey (€5/person each way, ~20 min).
Volcano crossing time
10 minutes from the Old Port, 20 minutes from Athinios Port.
The crater hike
About 30 minutes to reach the crater. Wear sturdy closed-toe shoes. No shade on the path.
The hot springs
Recommended for good swimmers. The iron-rich water can stain light fabrics — bring a dark swimsuit.
