Algeria's north is fairly fertile with agricultural land between forested mountains. There are two mountain ranges dominating this region, Atlas and Kabylia.
The desert starts quickly after one leaves the coastal area, at first only as rocky desert, but soon there are large sandy areas. Desert dominates large parts of Algeria's vast territory, and Algeria is among the countries filling most of the world's largest desert, Sahara. There are some settlements all over the desert region. In the south of Algeria the large massif Hoggar is found.
