As autumn paints Rome in warm golden hues, the beloved Sagra delle Castagne (Chestnut Festival) returns to the historic Castelli Romani hills just outside the city. Taking place throughout October and early November, this cherished annual tradition celebrates one of Italy's most iconic autumn delicacies: roasted chestnuts. The festival transforms the picturesque hill towns of Ariccia, Genzano, and Rocca di Papa into vibrant celebrations of harvest season, with cobblestone streets lined with vendors roasting chestnuts over open flames, their smoky-sweet aroma filling the crisp autumn air.

Local families have been perfecting the art of roasting chestnuts for generations, and the festival offers visitors an authentic taste of this time-honored tradition. Beyond the chestnuts themselves—served hot in paper cones, perfect for warming your hands on cool October evenings—the festival showcases the entire gastronomic wealth of the Castelli Romani region. Food stalls offer local specialties including porchetta (roasted pork), wood-fired pizza, porcini mushrooms, and the area's excellent white wines from Frascati and Marino. Live folk music performances, traditional dancing, and artisan craft markets create a festive atmosphere that draws both Romans and international visitors. The origins of chestnut cultivation in the Castelli Romani date back centuries, when chestnuts served as a staple food for rural communities. The sweet chestnuts (castagne dolci) grown in these volcanic soils are particularly prized for their size and flavor. During the festival, visitors can learn about traditional harvesting methods, watch demonstrations of chestnut processing, and even participate in guided walks through ancient chestnut groves. Accessibility from Rome is remarkably easy, with regional trains departing regularly from Termini Station to Albano Laziale, Marino, and other Castelli Romani towns. The journey takes just 30-45 minutes and offers spectacular views as the train climbs into the hills overlooking Rome. Many visitors combine the festival with exploration of the area's stunning crater lakes—Lago Albano and Lago di Nemi—and visits to historic papal residences like Castel Gandolfo. Peak festival weekends in late October draw the largest crowds, particularly Sundays when Roman families make traditional excursions to the hills. For a more relaxed experience, weekday visits offer the same delicious food and autumn atmosphere with considerably fewer people. Most festival activities run from late morning through evening, with the most atmospheric moments arriving as twilight descends and the glow from roasting fires illuminates the medieval town centers. The festival is free to attend, with visitors paying only for food, drinks, and any crafts they wish to purchase. Dress in layers for changeable autumn weather, and wear comfortable walking shoes for navigating the hilly terrain and cobblestone streets. The experience offers a perfect escape from the city, combining natural beauty, culinary traditions, and the warmth of Italian community celebrations.
