Explore the natural beauty and wild scenery of the Santorini caldera.
One of Santorini’s definitive landmarks is the active volcano and caldera dominating the island’s geography. This geological wonder shaped Santorini’s emergence while bestowing unique characteristics. Exploring the volcano and hot springs grants visitors insight into the powerful natural forces that created Santorini.
How was the Santorini caldera formed?
Santorini was originally a single landmass before massive eruptions around 1600 BCE caused the center to collapse and the sea to rush in. This cataclysmic event formed the flooded caldera, gave rise to the current crescent-shaped Santorini, and spread volcanic matter that shapes the islands’ rock and soil.
In the caldera sea, Nea Kameni is Santorini’s present day active volcano formed by continued lava flow after the Minoan eruption. Boats offer close-up access to see smoke rising and feel the heat. Hiking the rugged landscape reveals petrified magma and sulfuric hot springs. Nearby Palea Kameni, the caldera’s oldest lava island, also provides boat or hiking access to volcanic features like hot springs.
Inland at Santorini’s southern tip, ancient eruptions formed the breathtaking rock formations of Cape Exomitis. Hike among wind-carved lava statues, jagged cliffs, and sea-filled craters at this wild headland shaped by the volcano’s activity.
What thermal springs are at the caldera?
Thermal springs enriched by the complex volcano system exist around Santorini, offering visitors the chance to soak in these mineral-rich waters. On Palea Kameni, sink into the warm sea at the natural hot springs where the ocean mixes with underground heat.
Nea Kameni sits in the heart of the caldera, and features warm and therapeutic waters. These consist of sulfur, iron, and manganese, which have been known to be beneficial to the body.
The popular beach town of Kamari houses the inviting Ancient Thera Hot Springs. Relax in a series of open-air pools facing the sea. The natural spring water provides relaxation as well as purported therapeutic benefits.
