Lake Vico
Nature reserve in the Cimini Mountains, province of Viterbo — Tuscia, Lazio
A lake born from a volcano
Lake Vico, also known as Lake Cimino, is a volcanic lake in central Italy located in the province of Viterbo. At 507 metres above sea level it holds the altitude record among Italy’s major lakes, and it is enclosed by the Cimini Mountains, in particular Monte Fogliano (965 m) and Monte Venere (851 m).
Source: Wikipedia — Lago di VicoThe basin formed roughly 90,000 years ago after the collapse of a volcano, and the resulting caldera today hosts beech, oak and chestnut woods that stretch down to the lake’s calm waters. A local legend instead traces its origins to Hercules, said to have made the waters gush forth while challenging the local inhabitants.

A nature reserve in the heart of Tuscia
The Lake Vico Nature Reserve is a protected area spanning the municipalities of Ronciglione and Caprarola, established by regional law in 1982 and expanded in 2008; it has since been managed by the Ente Monti Cimini, which took over from the Municipality of Caprarola as the responsible authority. The reserve covers the entire lake basin and extends across 4,109 hectares, including the slopes of Monte Fogliano and Monte Venere.

🏞️ The highest of Italy’s major lakes
At 507 metres above sea level, Lake Vico holds the altitude record among Italy’s major lakes, a fact that sets it clearly apart from the nearby Lake Bracciano and Lake Bolsena.
Source: Wikipedia — Lago di Vico🛶 No building speculation
Having been a protected area since 1982, the lake has escaped the building speculation that affected other bodies of water in Lazio: only one small residential area, Punta del Lago, built in the 1960s-70s in the municipality of Ronciglione, sits on its shores.

The entire Vico caldera is prime territory for growing the “Tonda Gentile Romana” hazelnut, the basis of the Nocciola Romana DOP: a sector that alone accounts for around 40% of national hazelnut production in the area between the Cimini and Sabatini mountains.

The entire Vico caldera is prime ground for growing the Cimini Mountains hazelnut, of the “Tonda Gentile Romana” variety, the origin of the Nocciola Romana DOP. The volcanic, cool, organically rich soils of the hazelnut groves yield a nut with a lower fat content than other varieties; harvesting traditionally runs from mid-August to mid-November.
Source: Parchi Lazio — Nocciola dei Monti CiminiHazelnut growing today involves dozens of towns across Tuscia — including Ronciglione, Capranica and Caprarola — with thousands of active producers in the area, making it one of the largest hazelnut-growing regions nationally and in Europe, second only to Turkey.

The Berberi horse race in Ronciglione
🐎 Feast of San Bartolomeo — late August
Ronciglione hosts the “corse a vuoto” palio, also known as the Berberi race: riderless horses run about one kilometre through the streets of the old town. Linked to the feast of the patron saint, San Bartolomeo, it takes place around 20 August and is considered the most important historic game in Lazio.

A short drive from the lake, in the village of Caprarola, stands Palazzo Farnese: begun in 1530 as a pentagonal fortress designed by Antonio da Sangallo the Younger for Cardinal Alessandro Farnese, it was later transformed into a lavish Renaissance residence by Jacopo Barozzi da Vignola from 1547 onward, after the cardinal’s election to the papacy as Paul III.
Source: Lazio Nascosto — Palazzo FarneseThe building, with its distinctive pentagonal plan and circular central courtyard designed by Vignola, holds over 6,000 square metres of frescoed walls; its most famous rooms include the Room of Hercules, the Room of Farnese Deeds and the Room of the Map of the World. The palace looks onto Renaissance gardens laid out between 1565 and 1630 by Giacomo del Duca.
