Rugged Zahara, strung around a vertiginous crag at the foot of the Grazalema mountains, overlooking the glittering turquoise Embalse de Zahara (Zahara Reservoir), hums with Moorish mystery. For over 150 years in the 14th and 15th centuries, it stood on the old medieval frontier facing off against Christian Olvera, clearly visible in the distance. These days Zahara ticks all the classic white-town boxes and, with vistas framed by tall palms and hot-pink bougainvillea, its streets invite exploration. It's also a great base for hiking the Garganta Verde, so it's popular. Visit during the afternoon siesta, however, and you can still hear a pin drop.
The precipitous CA9104 road over the ultra-steep 1357m Puerto de las Palomas (Doves' Pass) links Zahara with Grazalema (17km south) and is a spectacular drive full of white-knuckle switchbacks.
