In the northernmost part of the province of Chieti, the landscape is more arid, whereas in the south it is smoother and full of small scattered settlements. A large part of the Majella massif, which is the second highest mountain of the Apennines chain after the Gran Sasso d’Italia, is also located in the province of Chieti. After the limestone peaks, the landscape of the rolling hills at the foot of the Apennines is characterized by extraordinary phenomena, such as the impressive ravines.
Many areas of the surface are covered with forests with high biodiversity. In this province there are many nature reserves to safeguard, enhance, and promote the heritage of spontaneous forests in the region, and to create natural barriers of self-defense for crops and vineyards.
The coastal area is called “Costa dei Trabocchi”, for the presence of picturesque wooden fishing structures, which have now become an attraction for tourists. The coast in the province of Chieti is one of the most diversified in the region, with alternating low and sandy stretches of beach or pebbles and high and rocky cliffs.
