The story

About the hot springs of Palea and Nea Kameni

The warm springs lie around Palea and Nea Kameni, two small isles that rose from the sea after the volcano's eruption of 1570. The water is dark and reddish, colored by sulfur, iron and manganese, and warm rather than hot. The springs are natural and sit in the bay of Agios Nikolaos.

A visit is a boat trip out of Fira bay. Once the boat anchors, you swim in the warm water for about 30 minutes, and many people smear on the mud. Bring an old swimsuit and a spare, because the sulfur smell clings. From Nea Kameni, walkers can climb toward the smoking crater.

  • 1570 Year of the eruption that formed the isles
  • 30 to 35 degrees Celsius Water temperature, warm rather than hot
  • About 30 minutes Time spent swimming at the bay

Getting there, cost and time

Getting there

Boats leave from Fira bay, and the springs lie near Nea Kameni, about 20 minutes by boat.

What it costs

Paid for as a boat trip that includes the swim at the springs.

Time

About 30 minutes in the water.

Good to know

  • Wear an old swimsuit and bring a spare, since the sulfur smell is hard to wash out of swimwear.
  • Light-colored swimsuits can be stained by the sulfur and iron in the water, so avoid them.
  • The water is warm rather than hot, at about 30 to 35 degrees Celsius.
  • Vents on Nea Kameni are seen from a safe distance; scientists monitor the underwater activity and the springs are safe to visit.
