The Palea Kameni hot springs sit beside a volcanic islet in Santorini’s caldera and are reached by boat tour. The swim takes you from the boat to yellowish, sulphur-rich water near the shore, where some areas are shallow enough to stand. The water is usually only a few degrees warmer than the sea, so expect a mineral-water swim rather than a hot bath. The volcanic setting and boat ride are part of the experience, but the swim is best suited to confident swimmers.
Reaching the springs from the boat
Boat tours stop offshore, and you swim from the boat to the bathing area. The crossing is in open water, which can feel cold before you reach the springs. One account notes that life jackets were not provided, so consider your swimming ability before joining the swim.
What the water is like
The water near the shore is yellowish from sulphur associated with the volcanic area. Some parts are shallow, and the temperature is only a few degrees above the surrounding sea. Sulphur can leave marks on swimwear; darker or older clothing is a practical choice.
