Hot Springs of Santorini
Hot Springs of Santorini in Greece Tours
The Hot Springs of Santorini are located around the volcanic islets of Nea Kameni and Palea Kameni, within the spectacular Santorini caldera. Created by the island’s ongoing volcanic activity, the springs are known for their warm, mineral-rich waters and distinctive volcanic surroundings.
Visitors typically reach the hot springs by boat, often as part of a caldera excursion that also includes Nea Kameni. At Palea Kameni, boats stop near the springs, allowing visitors to swim in the warmer waters and experience the unique volcanic environment surrounded by the Aegean Sea.
The combination of volcanic landscapes, warm mineral waters and panoramic caldera views makes the Santorini Hot Springs a popular experience for visitors exploring the island’s natural heritage.
