Sorgenti dell'Asinello — 'Springs of the Little Donkey' — are natural sulphurous thermal springs in Italy, likely in the volcanic or Apennine thermal zone, whose evocative name reflects the traditional Italian practice of naming springs after local animal associations or folk memories of the landscape. These natural springs, accessible in the Italian countryside, embody the terme libere (free thermal waters) tradition where natural sulphurous or mineral water flows freely and is available for bathing without charge, a democratic thermal heritage that survives particularly in Tuscany, Lazio, and the Apennine foothills. The surrounding Italian rural landscape, with its olive groves, vineyard terraces, and medieval village silhouettes, provides the characteristically timeless Italian countryside setting.

Insider tip — Sorgenti dell'Asinello is a small sulfurous spring cluster in the volcanic countryside near Viterbo, just meters from the better-known San Cristoforo source. The springs share the same geothermal origin from the Cimini volcanic arc and emerge at classic Viterbese temperatures of 38°C. The bucolic surroundings of hazelnut orchards and medieval hilltowns make this corner of Lazio feel timeless.
