Italy sits on one of Europe's most active volcanic systems. The result: hot springs EVERYWHERE — from the sulfurous waterfalls near Rome to the volcanic pools of Ischia, the Tuscan cascade terraces of Saturnia, and the world-famous mud baths of Abano Terme. The Romans built an empire on thermal bathing — the Baths of Caracalla held 6,000 people, and every Roman town had public baths. Today, Italy has 380+ registered thermal establishments. This guide ranks the 15 best by experience type: free natural pools, day spas, and luxury resorts. Terme near Rome →
