Few white towns are as generically perfect as Grazalema, with its spotless whitewashed houses sporting rust-tiled roofs and wrought-iron window bars, and sprinkled on the steep, rocky slopes of its eponymous mountain range. With hikes fanning out in all directions, Grazalema is the most popular base for adventures into the Parque Natural Sierra de Grazalema.  [lonelyplanet.com]
