The Sahara Desert is a huge desert region, but it contains several smaller geographical areas with different types of terrain. These are sometimes informally described as deserts within the Sahara. The main types include ergs, which are large areas covered by sand dunes; regs, which are flat plains covered with gravel and stones; and hamadas, which are rocky plateaus. In Morocco, Erg Chebbi near Merzouga is one of the best-known sandy regions of the Sahara. It features extensive golden dunes and is known for its distinctive desert landscape. Erg Chigaga, located farther west in southern Morocco, is another major dune area. Therefore, there is no separate desert located inside the Sahara as a whole. Instead, the Sahara is made up of numerous distinct desert landscapes, including sandy dune fields, rocky plateaus, and gravel plains.
