The largest Arab and African country — and the least touristically discovered: its secret and its charm. White Algiers cascades to the Mediterranean with its UNESCO Ottoman Casbah and the Great Mosque (the world's tallest minaret); radiant Oran keeps its Andalusian soul west. Saudis currently need an embassy visa (rules are easing fast — check before planning); ~5h direct from Jeddah; 100 DZD ≈ 2.8 SAR; April-June and September-October shine.
