A complete guide to the Italian chestnut groves: Mugello, Lunigiana, Sila, Campania, Aspromonte. When to visit them, the most famous chestnut festivals, harvesting, products, and a thousand-year history.
The chestnut tree ( Castanea sativa ) is one of the trees that made Italy more than marble or laurel. For centuries, in the Apennine and pre-Alpine mountains, chestnuts were the main food of the rural populations, bread, flour, polenta, soups. The chestnut was called the "bread tree" or the "tree of life." It isn't bucolic poetry: it's a subsistence economy. The chestnut woods in Italy, today, are one of the most beautiful autumn landscapes in Europe, and almost no one talks about them as they should.
Italy has about 780,000 hectares of chestnut groves (ISTAT/INFC data), the largest area in Europe after Spain and France. Of these, about 140,000 are fruit-bearing chestnut groves (traditional silviculture) and the rest are spontaneous, often abandoned woods. The regions with the most chestnut groves: Tuscany (150,000 ha), Campania (100,000 ha), Calabria (80,000 ha), Piedmont (70,000 ha), Liguria (60,000 ha).
The reality is that many Italian chestnut groves have been abandoned for decades, the post-war rural migration left without care trees that require pruning, undergrowth clearing, and regular harvesting. An abandoned chestnut grove doesn't die, but it produces less, gets sick (gall wasp, bark canker), becomes impassable. The recovery of the chestnut groves is one of the most urgent issues of Italian forestry policy.
The Mugello, the valley north of Florence between the Apennines and Chianti, has one of the densest concentrations of fruit-bearing chestnut groves in Italy. The area between Marradi (FI) and Palazzuolo sul Senio (FI) is particularly rich, and produces the Marruca, a prized local marron variety, the base of the famous Marradi festival. Centuries-old chestnut groves along the SS302 and the secondary roads between Marradi and Palazzuolo, accessible on foot from the roadside.
The Lunigiana, the territory around Pontremoli and Fivizzano (MS), produces the Farina di Neccio della Garfagnana DOP, the most prized chestnut flour in Italy. The chestnut groves of the Lunigiana are among the oldest and best preserved in the country, trees 300-500 years old with circumferences of 4-5 meters. The area of Comano, Licciana Nardi, and Filattiera has chestnut-grove landscapes that look like they came out of a Kurosawa film (the same autumn effect, the same silence).
Campania is the main producer of the Castagna di Montella IGP, the most famous chestnut in Italy. Montella (AV), on the southern slope of the Partenio, has a local variety (Palommina, Verdola, Castagna di Montella) with particularly sweet and crunchy flesh. The Montella chestnut groves cover about 5,000 hectares of the municipality. Visit: October, the local festival, direct sale from the farmers in the square.
The Sila plateau (CS-KR-CZ) has majestic chestnut groves above 1,000 m of altitude. The area of San Giovanni in Fiore and Camigliatello Silano has chestnut woods alternating with silver firs and larch pines, a landscape completely different from the stereotyped image of Calabria. The Sagra della Castagna di San Giovanni in Fiore (October) is one of the most attended in the South.
The Bosco di Sant'Antonio is the oldest beech forest of the Apennines, but in the lower bands (900-1,100 m) it has old chestnut groves that in autumn create spectacular colors. Reachable from Pescocostanzo (AQ), 15 km from Roccaraso. Free access, well-marked trails, no tourist infrastructure, perfect for those who want the woods without the crowd.
| Period | What to expect | Activity |
|---|---|---|
| September | Green leaves, burrs still closed | Walks, mushrooms (if it rains) |
| First half of October | Yellowing, burrs start to open | Harvest begins, local festivals |
| Second half of October | Peak colors, full harvest | Main festivals, roast chestnuts, markets |
| First half of November | Fallen leaves, bare woods | Silence and austere beauty, late mushrooms |
Yes, but with limitations. Gathering chestnuts in the Italian woods for family use is generally allowed in limited quantities (5 kg/day per person in most regions). In the national parks and the nature reserves, gathering may be prohibited or require specific permits. In private woods, the owner's consent is necessary. Commercial gathering requires authorization. Always check the regional regulations before gathering.
In the Italian commercial sense, the "marrone" indicates chestnut varieties selected for fruit use (large, with an internal septum that doesn't penetrate the flesh, easily peelable), while "castagna" indicates the wild or semi-wild varieties (smaller, with an internal septum adhering to the flesh). It isn't a botanical distinction, it's a commercial one. The Marrone di Castel del Rio, the Marrone di Marradi, the Marrone del Mugello are all varieties of Castanea sativa selected for the premium markets.
Chestnut trees ( Castanea sativa ) are among the long-lived trees of Italy. A chestnut tree can live 500-600 years with adequate care. There are Italian chestnut trees of documented age over 1,000 years, the most famous is the Castagno dei Cento Cavalli on Etna (Municipality of Sant'Alfio, CT), with a circumference of 57 m and an estimated age of 2,000-4,000 years. It's the largest and probably the oldest chestnut tree in the world. Free visit from the provincial road to Sant'Alfio.
The Dryocosmus kuriphilus, known as the chestnut gall wasp, is a parasitic insect native to China that arrived in Italy in 2002 (the first report in Piedmont, probably introduced with plant material from nurseries). Between 2005 and 2015 it devastated about 70% of the Italian chestnut production, causing damage worth hundreds of millions of euros. The response: the biological introduction of its natural antagonist, the parasitoid Torymus sinensis, starting in 2010. Today the gall wasp is under biological control in most Italian regions, but production hasn't yet recovered the pre-2002 levels.
The main chestnut festivals in Italy (all in October): Sagra della Castagna di Marradi (FI), the most attended in Tuscany; Sagra del Marrone di Castel del Rio (BO), IGP chestnuts, a medieval village, local specialties; Sagra delle Castagne di Vallerano (VT, Lazio), Cimino chestnuts, local wine, a historic procession; Sagra del Marrone di Sorbo Serpico (AV, Campania), the Irpinia area, marrone IGP; Sagra della Castagna di San Giovanni in Fiore (CS, Calabria), Sila, a mountain setting, Calabrian specialties.
Chestnut flour has come back into fashion in the gluten-free era, it contains no gluten, has a moderate glycemic index, is rich in potassium and vitamin C. But real chestnut flour, dried in the metati (small stone buildings where the chestnuts are smoked for weeks), is hard to find outside the Lunigiana and the Garfagnana. The one sold in supermarkets is almost always industrially dried, it has a completely different aromatic profile, less complex.
The best porcini in Italy often grow in the chestnut groves, not in the beech woods or the fir woods as many believe. The undergrowth of the chestnut grove, with its layer of decomposing leaves and the acidic soil, is the preferred habitat of Boletus edulis in many Apennine areas. September-October in the Tuscan and Campanian chestnut groves: look for the porcini before the chestnuts.
What to take home from a visit to the chestnut woods: Garfagnana chestnut flour (DOP, €8-12/kg at the traditional mills of Castelnuovo Garfagnana); chestnut honey (the most bitter and aromatic of the Italian honeys, €10-15/250g at the local beekeepers); artisanal marrons glacés (Aosta and Turin produce the most prized Italian version, €30-60/kg, not a cheap souvenir but it lasts months); necci (chestnut-flour crepes, only in Tuscany and the Lunigiana, not exportable fresh but the flour to make them is).
Walking in a chestnut grove in mid-October is a multisensory experience: the sound of the burrs falling, the earthy smell of the rotting leaves, the dull thud of the chestnuts on the ground, the rustle of the squirrels among the branches. The autumn chestnut groves of the Apennines on a sunny day with morning mist are among the most beautiful natural experiences in Italy, and they cost zero euros.
To gather chestnuts legally and safely: check the regional regulations (every region has its own rule, typically 5 kg/person/day for family use), go in the central hours of the day (in the morning the snakes sleep on the trail absorbing the heat), bring a basket or a cloth bag (avoid plastic bags that make the chestnuts rot), wear gardening gloves to open the burrs (the spines penetrate the skin), choose heavy chestnuts without holes (the holes indicate the presence of the worm, the larva of the Cydia splendana).
Fresh chestnuts keep up to 2 weeks in the refrigerator in a paper bag (not plastic). For longer storage: immerse the chestnuts in cold water for 9 days, changing the water every day (the traditional method, which eliminates the worms and delays the mold). Then dry them and put them in the fridge. Or: freeze them directly after the water treatment. Frozen chestnuts last 6-12 months and are cooked directly from frozen.
The Farina di Neccio della Garfagnana DOP is bought from the traditional mills of the Garfagnana (Castelnuovo Garfagnana, LU) or from the artisan shops of Barga, Piazza al Serchio, and Sillano. Online it's distributed by the Consorzio della Farina di Neccio della Garfagnana (www.farinaginecchio.it). The Farina di Castagne della Lunigiana DOP follows the same channels. Prices: €8-12/kg from the producer, €12-18/kg in the city shops.
The chestnut runs through all of medieval and Renaissance Italian literature as a symbol of autumn abundance and peasant life. Giovanni Pascoli (1855-1912), the Romagnol poet who lived much of his life at Castelvecchio di Barga in the Garfagnana, wrote "Castagne" (Myricae, 1891), one of his best-known poems. Carlo Levi in his "Christ Stopped at Eboli" (1945) describes the chestnut groves of Basilicata as part of the survival economy of the southern peasants. Ignazio Silone in "Fontamara" (1930) makes the chestnut the food of the lowliest. The chestnut is the plant of the humble of the Apennines, not of the aristocracy (which preferred the fruits of the formal gardens), but of those who lived off the mountain.
