A gentle walk around Lazio's smallest and most scenic volcanic crater lake, through mixed beech and hazel forest. Excellent birdwatching opportunities with great crested grebes, herons and migratory birds.
Lago di Vico is one of Lazio's most scenic volcanic crater lakes, cradled in the Cimini hills of the Viterbo province within the Riserva Naturale Lago di Vico, near the Renaissance town of Caprarola. The circumnavigation is a gentle walk of around 11km with minimal elevation over about 3 hours, following the cycle-and-foot path and quiet lakeside roads that ring the water. The usual start is near Caprarola or the lakeside parking areas off the road that descends from the town; access is by car from Viterbo or Caprarola, with limited COTRAL bus links to Caprarola itself. Surfaces are a mix of flat asphalt path, packed gravel and short road sections, making it one of the easier long walks in the region, suitable for families and casual walkers. The route runs through mixed beech and hazel woodland, the hazel groves being a regional crop, with sections close to the reed-fringed shore and others set back in the trees, offering a balance of shade and open lake views. The reserve is renowned for birdwatching: great crested grebes, herons, coots and many migratory waterbirds gather on the lake and in the marshes, especially around the Lestra del Lupo nature area. Above the lake rises Monte Venere, an optional steeper detour for those wanting a summit. The grand Palazzo Farnese at Caprarola is visible from parts of the trail and makes a fitting cultural pairing. There are no refuge huts, but Caprarola's cafes and the lakeside bars in season provide refreshment and water; carrying a bottle is still advisable on the wooded stretches. With its flat profile, birdlife and volcanic scenery, the Lago di Vico loop is an accessible and rewarding day out in northern Lazio.

Accessibility
Parts of the loop follow flat asphalt and packed-gravel cycle path that may suit sturdy strollers and some wheelchair users in dry conditions, but road sections and uneven gravel mean the full circuit is not fully accessible.
