A treasure trove of history and nature 💎 Lake Nemi, anciently called "Diana's Mirror", is one of the most evocative stops in the entire Park of the Roman Castles. Perfect for a loop tour or as a scenic detour. The descent towards the shores offers views that seem painted, with the perched village overlooking the blue water.

Unfortunately, the tour is not practicable at this time due to some fallen trees along the route, but it will surely be cleared of these trees as soon as possible and it is a beautiful ride.

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.

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.

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.

Starting from Lariano it is a long walk. The only advice is to do it in company because you will meet flocks of sheep, sometimes, without shepherds.

Fantastic spot reachable by car or on foot from both Nemi and Genzano where you can rest along the lake, camp out and feed the ducks.
