Santorini Volcano and Hot Springs Boat Tour Guide
Hike the active volcano of Nea Kameni and swim in the warm Palea Kameni hot springs on one of the most popular Santorini boat trips.
The Santorini caldera
Santorini's dramatic crescent shape was formed by one of the largest volcanic eruptions in history, around 3,600 years ago. In the centre of the flooded caldera lie the volcanic islands of Nea Kameni and Palea Kameni.
Hiking Nea Kameni
Boat tours stop at Nea Kameni, where a short hike leads to the crater of the still-active volcano, with steaming vents, black lava fields and panoramic views of the caldera cliffs.
Swimming in the hot springs
At Palea Kameni you can swim to the warm, mineral-rich hot springs, famous for their orange-tinted water. Bring an old swimsuit, as the iron-rich water can stain.
