The Hot Springs of Nea Kameni, on the volcanic islet of Nea Kameni near Santorini, offer iron-rich, sulfurous water known for its orange tint, pH 6.5. Outdoor bath and sauna, plus massage, in a unique volcanic Aegean setting.
Insider tip — The hydrothermal springs of Nea Kameni, the active volcanic island at the centre of the Santorini caldera, are unique in the Mediterranean. The warm ferruginous and sulfurous waters tint the sea yellow-green around the volcano. Accessible by boat excursion from Santorini — swimming in these steaming waters between the black lava flows is a striking experience of living geology.
