One of Morocco’s little known city sites where old world tradition and modern technology meet hand in hand is Casablanca’s Derb Ghallef. Derb Ghallef in Casablanca is worth visiting on a one-day Casablanca Tour. Derb Ghallef is essentially an enormous flea market and the center of distribution for black market goods and services in Casablanca, Morocco. The noise and bustle of the auction block, the bargain prices of the flea market and its goods are defining features of today’s Derb Ghallef. There is no better way to see a live flea market on a Casablanca Tour then Derb Ghallef.
