Djibouti, on the Horn of Africa, is a mostly French- and Arabic-speaking country of dry shrublands, volcanic formations and Gulf of Aden beaches. It’s home to one of the saltiest bodies of water in the world, the low-lying Lake Assal, in the Danakil Desert. The nomadic Afar people have settlements along Lake Abbe, a body of saltwater featuring chimneylike mineral formations.
