Swim in naturally warm volcanic waters in the heart of the Santorini caldera — a truly unique experience.
The Santorini Hot Springs are one of the most unusual natural attractions in the Aegean — geothermally heated waters that bubble up from volcanic vents near Palea Kameni, the older of the two volcanic islands in the caldera. The water here is naturally warm, rich in minerals, and tinged a yellowish-brown from the sulphur and iron oxide seeping up from below.
Swimming in the hot springs is a memorable experience — the contrast between the cool Aegean and the warm volcanic water is immediately apparent, and the rust-coloured plume spreading from the springs into the blue caldera makes for remarkable photos. The minerals are said to be beneficial for skin, and many guests stay in the water far longer than planned.
Our catamaran anchors nearby and guests swim across to the hot springs area — a short, easy swim in calm caldera waters. It is a highlight that guests frequently mention in their reviews as one of the most memorable moments of their Santorini holiday.
Book your sailing cruise and experience this volcanic natural wonder in the heart of the caldera.
