The best MTB trails around Lago di Nemi

A stage to definitely include in the tour of the Roman castles

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.

So, for the Mille Curve, the advice is clear: a good mountain bike, perhaps with grippy tires, given the occasional mud. Being in the Alban Hills—or rather, Castelli Romani—the park is always open, but trust me: daylight is your best friend. At night? Well, it's fascinating, but maybe leave that to adventure stories! In short, appropriate gear, plenty of light, and off you go: the curves await!

The Mille Curve, from Colle Giovannone toward Via Veda dei Corsi, is one of those trails that make you smile just by its name... and then it keeps its promise. Continuous curves, a fast pace, trees passing so close that they remind you that here you ride with your head and cool head. It's not extreme, but it must be respected: even at 10–15 km/h, bumping your shoulder against a tree trunk isn't exactly a relaxing massage. You need agility, a forward-looking attitude, and a desire to have fun. Uphill, everything changes: the thousand curves remain, but they become an exercise in fluidity. In mud (like yesterday), you need to lighten the load, use agile gears, and use the e-bike's motor sparingly: too much assistance and the rear wheel loses grip. It's only technical in the last section (uphill, the reverse is true downhill); the rest is pure flow through the woods. A trail to do, do, and do again.

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.

Pit stop for anyone who loves to visit the Pratoni del Vivaro by mountain bike.
