Vallerano (a village of approximately 2,600 inhabitants in the Monti Cimini, province of Viterbo. 20km south of Viterbo on the volcanic basalt hills of the Cimino massif, at 460m altitude) is the village that the Lazio chestnut calendar has made famous in the specific and self-limiting way of the Italian sagra (local food festival): the Sagra delle Castagne di Vallerano (the October chestnut festival, one of the oldest and most attended local food festivals in northern Lazio, held annually on the last Sunday of October and the preceding weekend) draws 20,000-30,000 visitors to a village of 2,600 for the specific occasion of eating roasted chestnuts (le caldarroste), drinking the new wine (il vino novello, the wine from the just-completed Cimini harvest), and experiencing the October Cimini landscape at its autumnal peak.
The Vallerano chestnut (the specific variety grown in the Cimini volcanic basalt soil, the basalt of the Cimino volcanic complex produces the specific mineral richness that the chestnut absorbs, giving the Vallerano castagna a sweetness and a dense texture that distinguishes it from the equivalent products from limestone or sandstone soils): the Cimini chestnut tradition is centuries old, the chestnut was the primary caloric source of the Viterbo province mountain communities before the introduction of the potato, and the specific varieties (the Marrone, the Marsol, and the Primofiore, the three principal Cimini varieties) that the Vallerano producers maintain in their chestnut groves represent a specific agro-biodiversity of genuine cultural significance.

Vallerano: Chestnuts, Village, and Landscape
The Cimini Chestnut Forest
The Bosco del Cimino (the chestnut and beech forest covering the Cimino volcanic massif between Viterbo and Ronciglione, one of the largest and most intact chestnut forests in central Italy) provides the landscape context for the Vallerano festival: the October forest (the chestnut leaves turning yellow-gold, the fallen chestnuts covering the ground, the specific smell of the forest in the first cool rains of autumn) is accessible by the forest roads from Vallerano toward Monte Cimino (1,053m, the Cimini summit, accessible by car on the Viterbo-Ronciglione road through the forest). The Cimino forest in October is the finest single autumn color display within 100km of Rome that is accessible without hiking.
Vallerano Medieval Center
The Vallerano historic center (the medieval borgo (historic village) on the hill, with the church of Sant'Andrea and the specific Cimini volcanic stone architecture of the compact village) is at its most animated during the festival weeks but worth visiting independently of the sagra for its specific authentic Viterbo-province character: the village piazza with the bar and the alimentari (small grocery shop), the medieval lanes, and the panoramic view over the Viterbo plain.
Q&A: Vallerano Chestnut Festival
How do I attend the Vallerano chestnut festival?
The Sagra delle Castagne di Vallerano (last weekend of October, check comune.vallerano.vt.it for the exact 2026 dates): arrive before 11:00 to find parking (the village parking fills quickly on festival Sunday, organized shuttle buses from designated parking areas on the Viterbo-Ronciglione road). The festival is free entry. The chestnuts, new wine, and local food products are bought at the producer stalls. Expect: crowds (20,000+ on the main Sunday), roasted chestnut smoke visible from 2km, the specific October Cimini light on the volcanic stone village, and the genuinely local quality of a sagra that hasn't been touristified because the local producers and the municipal organization maintain direct control.
