Volcanoes in Santorini
Santorini's volcano is a short boat trip from the caldera. Nea Kameni, a small uninhabited island in the middle of the flooded crater, has a rocky trail to the top and vents that puff steam and sulfur. Many visitors add a warm swim in the hot springs nearby, which come from the eruption of 1570. It is one of the most direct ways to see the island's volcanic past up close.

What to expect
Most visitors start with a ferry from Thira to Nea Kameni, about 20 minutes away. The island is nearly barren and is visited daily by many tourist boats through the summer, so the trail can be busy at midday. A rocky path climbs toward the top of the volcano, 2.6 km in total. Along the way you pass steam and sulfur vents, which you view from a safe distance. Near the top you can walk a full circuit of the crater rim and look down into the smoking crater.
Many boat trips also stop at the hot springs of Palea and Nea Kameni, formed after the 1570 eruption. At Agios Nikolaos Bay in Palaia Kameni, the boat anchors just meters away and you can swim in the warm sulfur waters for about 30 minutes. Some visits go on to the old port of Thirassia. Half-day tours on this theme usually run three to six hours, so the day can be short and simple or fill most of the afternoon. The trail and crater are best suited to people comfortable on uneven ground.

When to go
Summer brings red succulents to the crater, but the island is very hot from May onward. Spring and early autumn are milder for the climb, and weather can delay ferries and shuttles in winter.

- Bring water and a hat, especially in summer when there is little shade.
- Keep a safe distance from the steam and sulfur vents at all times.
