The second part of the route through the Castagniccia starts at the B&B Carpe Diem in Santa-Maria-Poggio. In the village you turn right.
The Corniche de la Castagniccia. The tourist corniche, high above the plain and the sea, follows the narrow D330, carved into the flanks of the mountains. It is one large viewpoint, 5 km long, with several bridges and tunnels along the way. From San-Nicolao the road becomes more difficult to drive on because there is sometimes water and loose gravel on the road.

In Folelli take direction Bastia until the hamlet of Tora. From there you drive to Vescovato, the capital of the Casinca region. It is a place with tall houses of dark schist, streets with steps and a central square with a fountain.

Restaurant A Teppa in Penta-di-Casina offers a beautiful view, you sit comfortably. The restaurant serves pizzas, salads and some main dishes.

Then keep towards Silvareccio, another pretty village on the mountain side. You continue to follow the signs to the Col de St.-Antoine. Watch out: the road gets worse here.
At the top, you can see the remains of the Saint-Antoine Monastery, founded in 1420 in the town of Casabianca. It is a very symbolic place in the history of Corsica. Meetings of the Corsican insurgents of the 18th century were held here. Today it is a ruin, all that remains of the building is the main structure with the bell tower, illustrated with frescoes and decorations that are still clearly visible. The monastery remained famous because in July 1755 Pasquale Paoli was proclaimed commander-in-chief of the Corsican nation. This date marks the beginning of his reign and the beginning of the island's independence, then under the rule of the Republic of Genoa. A commemorative plaque commemorates these events.

La Porta is located in the heart of the Castaniccia. In the 17th and 18th centuries, La Porta was mainly known for the export of wood, chestnuts and the bark of chestnut trees that were used in the tannery. However, better economic prospects in the coastal cities were a reason for many families to leave in the 19th century. La Porta has never recovered from this exodus, but it is precisely because of this that the atmosphere of historic Corsica has been preserved so well in this village. The Église St.-Jean-Baptiste has a beautiful bell tower 45 m high, a colorful facade and is one of the masterpieces of baroque art in Corsica. The church was completed in 1648 and has been listed as a historical monument since 1975.

In Morosaglia take the hairpin bend to the left towards Gavignano and Saliceto. You are now driving through the Bozio, the roughest area of the island. In San Lorenzo you follow the road to Cambia, Carticasi and Bustanico. Once you get through the hairpin bends, take the road to Sant'Andrea-di-Bozo. Beyond this village the road is very bad, winding and steep for about 1 km.
The road descends to Erbajolo where you have a beautiful view over the valley of the Tavignano, with the Monte d'Oro in the background.

After crossing the Tavignano you get a nice view of the Genoese bridge of Altiani. The bridge with three arches is in Louis XVI style. In order to preserve this heritage and to facilitate traffic, this bridge is no longer accessible to cars since July 2011 and has been replaced by a new bridge.
From here it is about 15 km to Corta, the end of this route.

The citadel of Corta has a rich history and was already transformed into a real fortress in 1419. After many years of different rulers, the citadel became the symbol of Corsica's independence. When the French occupied Corsica in 1769, the citadel became a military site. Now you will find the tourist office, a museum, an art institute and many historical archives. On the upper level is the castle. The Nid d'Aigle is the highest tower and overlooks the valleys of Restonica and Tavignano.
