On a wooded promontory at Forio, Mezzatorre Hotel & Thermal Spa occupies a 16th-century watchtower surrounded by seven hectares of pine forest and Mediterranean gardens. Rooms and suites sit within the tower and garden cottages, using tiled floors, pale fabrics and sea-facing terraces to echo the island setting. A thermal spa draws on Ischia’s mineral-rich waters, while the seawater pool and private bay are cut into the volcanic coastline below. La Baia and La Torre serve island produce in open-air settings, with footpaths winding between the tower, gardens and rocks at the water’s edge.
