After a long time, the water has returned, perhaps thanks to the rains of the past few months. There are also some tadpoles that have been placed in the fountain.

A rather scenic route, popular especially on weekends, ideal for mountain biking and gravel riding, it doesn't present any particular technical challenges. It's a great way to connect Genzano and Nemi without having to descend to lake level (which is worthwhile anyway), thus saving on elevation gain.

Fontan Tempesta is much more than a simple spring: it is a melting pot of history, geology, and legend located in the heart of the Castelli Romani Park, along the ancient path connecting Genzano, Nemi, and Rocca di Papa. 1. History and Name The name "Tempesta" has ancient roots. Some historians link it to the Tempesta family, local nobles in the Middle Ages. Others, more romantically, maintain that the area is so named for the frequency of intense atmospheric phenomena due to the particular shape of the Nemi volcanic crater, which "attracts" thunderstorms. 2. A Hydrographic Turning Point The spring is located approximately 600 meters above sea level. Geologically, the water that flows here is the result of filtering through the pyroclastic rocks of the Laziale Volcano. The fact that it has returned to flow after years of drought is an important sign of the restoration of surface water tables, often strained by the scarce rainfall of recent years. 3. Crossroads of Pilgrims and Wayfarers Historically, Fontan Tempesta was an obligatory stop for those traveling the Southern Via Francigena or for pilgrims heading to the Temple of Diana in Nemi. Even today, it is a favorite "turning point" for bikers and hikers because it represents the coolest and most sheltered spot in the forest, where the microclimate remains humid even in the height of summer.

The road is in poor condition, hasn't been cleared of tree stumps, and just before entering the village, it's blocked. There's a small, rugged and dangerous passageway, unsuitable for small children or those with mobility issues. You'll need to use your hands and feet to climb.

Nice spot to make pause and regain energy. Don’t expect water flowing during summer months

Hello Do you know if the trail is exposed in any places? We have a 15-month-old baby, and my wife is particularly afraid of the exposed sections. Thank you very much.

Ruins of a structure, likely an ancient farmhouse reclaimed by nature. Lush vegetation, including trees and creepers, has grown around the walls, giving the place a charming, wild feel. The Via dei Laghi is just a few meters away.
