The traditional Ciociaria land snail in the heart of the Simbruini Mountains
This edition has not been confirmed by the organiser to date. We recommend checking before going.
The Ciammaruca Festival is one of the most characteristic summer events in Trevi nel Lazio, a mountain village in the Province of Frosinone nestled in the heart of the Simbruini Mountains Regional Natural Park, the largest protected area in the Lazio region. Launched in 2024 by the local group Le Lumache dei Monti Simbruini, the festival has already secured a permanent spot in the mid-August calendar of the upper Aniene Valley, attracting locals, vacationers, and hikers passing through the park.
The absolute star is the ciammaruca, the term used in the local Ciociaria dialect for land snails. This is a humble, ancient ingredient of the rural cuisine of the Lazio Apennines, traditionally gathered after summer rains and cooked according to recipes passed down through generations. At the festival, the ciammaruche are prepared with simple, flavorful sauces, often based on tomato, garlic, chili, and wild herbs from the Simbruini meadows: a dish to be savored slowly, strictly by hand, in a perfect spirit of conviviality.
The festival takes place in the evening along Viale Cesare Battisti, in the center of Trevi nel Lazio, where food stalls open for tastings. Alongside the signature dish, there are other specialties of Lazio and mountain cuisine, all accompanied by local wine. The soundtrack is provided by live music, which transforms the main street of the village into a long, open-air banquet under the August stars.
The Municipality of Trevi nel Lazio, at an altitude of about 820 meters in the Lazio Region, is one of the most picturesque villages in the upper Aniene Valley: the historic center, dominated by the imposing Castello Caetani, preserves medieval alleys and panoramic views of the surrounding mountains. The village is a privileged gateway to the Simbruini Mountains Park, a paradise of beech forests, springs, and trails: the festival is the perfect opportunity to combine a day of hiking—such as the nearby Trevi waterfall or the Campo Staffi plateau—with an evening of authentic popular gastronomy.
The Ciammaruca Festival is part of a busy summer schedule that enlivens the village between July and August, alongside the Pro Loco Beer Festival, the Mountain Festival, and other local summer program initiatives. It is yet another reason to stay a few days in this corner of the mountain Ciociaria, where popular traditions are still lived with genuine enthusiasm by the community.
For 2026, the organizers of the Le Lumache dei Monti Simbruini group have not yet published the official date of the festival. The summer calendar of Trevi nel Lazio is already full of events—from the Beer Festival to the Mountain Festival—and the Ciammaruca Festival is expected, as in previous editions, during the week of Ferragosto. We recommend checking the event confirmation on the Simbruini Mountains Regional Natural Park channels before traveling.
By car: from Rome, take the A1 motorway to the Anagni-Fiuggi Terme exit, then follow signs for Fiuggi and the SR411 towards Altipiani di Arcinazzo and Trevi nel Lazio; alternatively, from Subiaco along the SR411 of the Aniene Valley. Parking is available near the center.
By bus: COTRAL connections from Rome and Frosinone via Fiuggi; the village is not served by a train station.
The festival takes place outdoors in the evening along Viale Cesare Battisti: at an altitude of 820 meters, August evenings can be cool, so it is best to bring a sweater. Admission to the event is free; dishes can be purchased at the food stalls.
