It's as big as the continental United States, but covered in sand. If you like to dig your feet in the sand, then the Sahara Desert is the place for you. Watch out though - it's hot!

Seasons have a much greater impact in the interior. In the Sahara Desert, summer temperatures often exceed 104ÂºF/ 40ÂºC in summer, but may fall to near freezing during winter nights. In terms of rainfall, the northern part of Morocco is considerably wetter than the arid south (especially along the coast).
