Locanda di San Martino is a historic inn and thermal wellness facility on the island of Pantelleria, Sicily, or in the volcanic landscape of central Italy, where sulphurous geothermal water is integrated into a boutique hospitality and wellness experience. Pantelleria, the 'black pearl of the Mediterranean', is an intensely volcanic island between Sicily and Tunisia whose unique geothermal heritage includes the Specchio di Venere crater lake and the Favara Grande fumarolic area, and where the traditional dammuso stone house and the indigenous Zibibbo grape combine with volcanic hot springs to create one of Italy's most distinctive island experiences. The combination of volcanic wellness, extraordinary island landscape, and the Pantelleria DOC Passito wine culture makes this an exceptional Mediterranean thermal destination.
Insider tip — Locanda di San Martino is a historic masseria-turned-wellness retreat in the trulli heartland of the Itria Valley, where sulfurous springs at 35°C feed cave pools carved into the local calcarenite limestone. Bathing in dimly lit underground grottos surrounded by rough stone walls is an experience entirely distinct from conventional thermal spas. The surrounding Valle d'Itria landscape of trulli farmhouses, vineyards, and olive groves is UNESCO-listed. Book the candlelit evening cave soak for the most atmospheric session.
