Landscapes of Algeria
As described on National Parks of Algeria
The landscape of Algeria consists of a small coastal area along Mediterranean Sea on its northern border and to the south, high plateaus and the Sahara Desert. Algeria’s coastal plain is narrow and hilly. The Atlas Mountains run from southwestern Morocco through northern Algeria to the eastern edge of Tunisia and separate Algeria’s coastal plain from the vast and barren Sahara Desert found in much of central and southern Algeria. These high plateaus in the north are mainly undulating, steppe-like plains stretching for nearly 400 miles. They rise up approximately 4,000 feet above sea level in the west and drop to around 1,000 feet as you move east.
Further south the Sahara Desert covers over 80 percent of Algeria.
