Nea Kameni Island
Walk on an active volcano in the middle of the sea
Nea Kameni is an uninhabited volcanic island at the center of Santorini’s caldera.
A visit here feels like stepping onto another planet. This black lava island is accessible by boat and offers visitors the rare chance to hike on an active volcano. Trails lead to the crater, where steam vents hint at ongoing geothermal activity. Along the way, guides explain the island’s explosive past and its role in shaping Santorini’s dramatic landscape. The views from the top are unforgettable, offering sweeping panoramas of the surrounding sea and the cliffside villages of the main island.
