If you get to Southern Italy, consider taking a boat to Ischia, near Capri, and you'll find one of the best undiscovered rest & relaxation spots on Earth -- NEGOMBO! There are over 20 natural thermal spas at various temperatures, & these are some seriously healing waters! The beach is a cove, so even during the busy season, feels secluded & special. The Roman Baths in this photo are my FAVORITE!
Key Italian cities and a link to temperatures and other information for each. Cinque Terre - September in the Fall would be my pick for the best time to go, followed by April or May.; Rome - Romans leave the Eternal City in July and August when it's hot and humid - the best time to travel to Rome is from mid-September to October.; Amalfi Coast - The best time to visit is April-June and September-October, when temperatures are the most pleasant.
Terme di Saturnia is a lush geothermal spring, with steamy water temperatures nearly 100 degrees Fahrenheit. The natural evolution of the landscape has smoothed out the spring and created waterfalls and shallow pools turning Terme di Saturnia into a giant, relaxing outdoor spa. While enjoying the posh lifestyle under the springs, take a moment and realize to understand this ancient luxury. The spring at Saturnia has flowed consistently for over 3000 years, and was even used by Roman nobles.
