Terme di Ischia

Ischia is Europe's richest thermal island: volcanic waters, therapeutic muds and a curative tradition spanning two thousand years.

Overview

Ischia sits on one of the most active hydrothermal systems in the Mediterranean: over 100 thermal springs feed both the large organised parks and the free natural pools scattered along the coast. The waters, rich in volcanic minerals, reach natural temperatures of up to 90°C at the hottest springs and have been used for centuries for recognised curative treatments, from arthritis to respiratory disorders.

Points of interest

  • Over 100 active thermal springs spread across the whole island
  • Organised thermal parks: Poseidon, Negombo, Aphrodite, Castiglione
  • Free, open natural springs such as Nitrodi and Sorgeto

Why visit it
