Pueblos Blancos — Whitewashed Andalusia

Grazalema is the highest of the white villages of the Sierra de Cádiz, set inside Spain's wettest natural park.

Setenil de las Bodegas is built directly under and into overhanging rock along the Rio Trejo canyon, with entire streets sheltered by stone ceilings rather than open sky.

Zahara de la Sierra is built beneath a Moorish castle ruin, overlooking a turquoise reservoir that floods what was once the valley floor below — one of the smaller and steeper of the Cádiz pueblos blancos.
