Spiaggia Fumarole

Anchor off this otherworldly stretch of beach near Sant'Angelo on Ischia, where the volcanic sand gets so hot it reaches up to 100°C just below the surface. People bury themselves in the sand here as a form of natural heat therapy — it's been used to treat joint and skin conditions for generations. It's a short trip from the thermal gardens of Aphrodite Apollon if you want to explore more of the island's geothermal scene.
