Thanks to the heavy rains this winter, Fontana Tempesta has begun to flow again, replenishing underground aquifers and creating an ideal habitat for amphibian life above ground. On an early spring morning, during a run along trail 512 from Genzano, I witnessed this small miracle myself: the fountain was flowing, its basins filled with tadpoles wriggling in the water, soon to become frogs and toads.
What is Fontana Tempesta?
“L’acqua Sorgiva Rallegra L’Anima del Camminatore” (Spring Water Gladdens the Soul of the Traveler)
Fontana Tempesta is a natural spring shaped by the volcanic geology of the Castelli Romani that has been used since ancient times. Its name, “Tempesta” (storm), is linked to its seasonal behavior: In spring or after heavy rainfall the fountain flows abundantly, while in drier periods it can diminish significantly or even dry up.
It is a magical place, reflecting myths in which springs were believed to be inhabited by nymphs or water spirits. It lies along the Via Francigena, serving as a scenic and contemplative stop for pilgrims, hikers, and nature lovers.
The Trail – CAI 512 “Le Piagge”
Trail 512, known as “Le Piagge,” is a wonder in its own right. In a relatively short distance, it offers views, scents, and sounds that capture the authentic beauty of the Castelli Romani. Starting from Genzano, the path reveals, in sequence, the town of Nemi perched on the crater rim, the lake shimmering below, and finally Fontana Tempesta itself.
The trail begins on a paved road, turning to dirt after about five minutes. A little further on, near a chestnut tree, a panoramic view toward Nemi opens up. From there, the path becomes increasingly enchanting as you descend into the sacred woods of the goddess Diana, drawing closer to the fountain.
The route is flat and straightforward: about 1.7 miles (2.7 km) to Fontana Tempesta—roughly 40 minutes walking or 20 minutes running. The entrance is easy to find, located at the end of Via delle Piagge in Genzano di Roma, making this trail accessible for hikers of all levels.

For longer walks and hikes, the CAI 512 continues all the way to Monte Cavo. At the fountain CAI 512 meets up with CAI 511, a trail that can take you to Nemi town.
