Why blue? Many tales, one certain spell: Morocco's most photographed town chose a single color between green Rif mountains and soul-mending calm. Outa el-Hammam and the kasbah, the famous stairways, Ras el-Ma's mountain spring, the Spanish Mosque sunset, and Akchour's waterfalls for the green adventure day. Sleep at least one night — dawn in the empty blue lanes is the photograph of a lifetime.
