Italy
Volcanic hot springs bubbling from the seabed, thermal gardens on cliffs, fumaroles in back gardens.
Steam rises off a rock pool where volcanic water meets the sea, the temperature swinging from scalding to cool with each wave. Fumaroles hiss behind garden walls. Whole terraces of heated pools step down the cliffs, each a different mineral shade.
Ischia is the Bay of Naples' biggest island, volcanic to its roots, with groundwater emerging hot enough to steam. Greeks and Romans channelled these springs, and the tradition never stopped: thermal gardens like Poseidon terrace twenty pools above Citara beach, fed by springs running from warm to 85 degrees, while at Sorgeto Bay hot water bubbles straight out of the seabed among the rocks. The Aragonese Castle has held its tidal islet since Greek antiquity, joined to the island by a causeway. Unlike its polished neighbour Capri, Ischia still farms: vineyards of Biancolella, rabbit hutches and fishing boats share the island with the bathers.
Couple
Soak at Sorgeto while the sun sinks toward Capri, then eat rabbit alla ischitana at a harbour table; romance here is geological.
Family
The thermal parks grade their pools by temperature, the beaches are sandy, and the ferry ride in counts as part of the outing.
Solo
Floating in volcano-heated water is inherently solitary, and Monte Epomeo's trails balance the soaking with a climb.
Coniglio all'ischitana, rabbit braised with tomato and wine in terracotta, is the island's ancient signature.
Biancolella, grown in volcanic terraces, pours bright and mineral beside the harbour.
