There's a line running down the spine of Italy where the rain that falls on the north side becomes Lambrusco and Parmigiano, and the rain that falls on the south side becomes Chianti and pecorino. That line is the Apennine ridge, and its most dramatic stretch — from the Passo della Cisa to the Passo del Cerreto — is this national park. On the Emilian side: dairy pastures where the milk that becomes Parmigiano Reggiano comes from cows grazing at 1,000 meters. On the Tuscan side: the Lunigiana, a hidden valley of castles and chestnut forests that was medieval Tuscany's frontier with the world. Between them: glacier lakes, wolf territory, and a silence that feels earned. Emilia-Romagna → · Tuscany →
Plan my Apennine trip →Lago Santo Parmense (1,507m): A glacier lake sitting in a cirque below Monte Marmagna. From Lagdei car park (1,300m, above Corniglio), it's a gentle 45-minute walk to the lake. The rifugio on the shore (Rifugio Mariotti, €45 half-board, open June-September) is one of the most peaceful overnight stays in the northern Apennines. At dawn, the lake surface is glass. Continue to Monte Marmagna (1,852m, 2h more) for views across the Po Plain to the Alps on clear days. More glacier lakes: Lago Verde, Lago Scuro, Lagoni — a chain of tarns dotting the ridge, each a different shade of blue-green.
The Apennine wolf is thriving here. The park sits on the corridor that wolves use to move between the western and central Apennines — at least 8-10 packs operate within the boundaries. You won't see them casually, but winter wolf-tracking excursions (organized by the park, free or low-cost) follow their prints in the snow. Golden eagle, peregrine falcon, eagle owl: the crags of the ridge are raptor territory. Mouflons (reintroduced) on the higher slopes. In autumn, the red deer rut echoes through the valleys.
The Tuscan side of the park drops into the Lunigiana, a valley that most tourists skip entirely on the autostrada to the coast. Their loss: medieval castles (Fosdinovo, Fivizzano, Pontremoli — all worth stopping for), chestnut forests that produce DOP flour (the chestnut was called "the bread tree" here for centuries), and a cuisine that's neither Tuscan nor Emilian but its own thing: testaroli (the oldest known pasta, cooked on hot stone), sgabei (fried bread), and torta d'erbi (herb pie). Pontremoli's Museo delle Statue-Stele has 4,000-year-old carved stone figures that predate the Etruscans.
Main access: Corniglio (Emilian side), Cerreto Laghi (ski resort on the pass), Fivizzano and Licciana Nardi (Lunigiana/Tuscan side). Nearest stations: Parma (then car 1.5h to Lagdei), Pontremoli (on the La Spezia-Parma line). Entry: free. Season: hiking June-October. Autumn foliage outstanding (beech + chestnut forests). Cerreto Laghi has a small ski area in winter. Stay: Corniglio (€45-70/night), rifugi (€40-50 half-board), Lunigiana agriturismi (€55-90). Eat: Emilian side — tortelli d'erbetta, Parmigiano 24+ months. Tuscan side — testaroli al pesto, torta d'erbi. Combine with: Parma (1.5h), Cinque Terre (1.5h from Pontremoli), Lucca (1.5h from Fivizzano).
