Fodor's Expert Review Imi-n-Ifri

Up a 6-km (4-mile) piste above Demnate is the natural stone bridge Imi-n-Ifri, where the diminutive River Mahseur has carved out a tunnel inhabited by hundreds of crows. A path twists down through the boulders and under the "bridge," where stalactites and sculpted hollows dramatize the natural rock formations. Women come to bathe in the stream because it is said to bring them good luck, but the crows are considered harbingers of doom. The legend associated with these birds—a St. George and the Dragon–type saga in which a lovely maiden is saved from an evil genie who, when destroyed by the brave hero, dematerializes into crows—is told in several variations by imaginative guides.
