The Apennine Mountains are a mountain range that runs down the length of Italy, forming the backbone of the country. Stretching about 1,200 kilometers (750 miles), they separate the eastern and western regions of Italy and are known for their diverse landscapes, including rugged peaks, rolling hills, and lush valleys. These mountains are home to various wildlife and plant species, making them an important ecological area. The Apennines also feature several national parks, such as Casentino Forests, which protect their natural beauty and provide opportunities for outdoor activities like hiking and skiing.
