Volcanic Hot Springs

The warm, iron-and-sulfur-tinted thermal waters in a cove off Palea Kameni, reached only by swimming from a boat in the caldera.

The call

Worth it if you're traveling with kids and you're traveling as a couple.

Short answer

Is Volcanic Hot Springs worth it?

Volcanic Hot Springs is a specialist choice, not a default stop. Go early or reserve ahead. Crowds are part of the cost.

The answer depends on your budget, time and travel style; the breakdown below shows who gets the most value.

Why

  1. 01

    A novelty more than a spa: the water is warmer than the sea and the rust-red minerals supposedly do your skin good, and it's fun to swim into a volcanic cove.

  2. 02

    The catch is that it's often only a couple of degrees warm, murky, and can stain swimwear orange.
