The Zaabal Tunnel (Tunnel de Foum Zabel) is one of the most remarkable historical and engineering landmarks located within the Ziz Gorges between Er-Rich and Errachidia. This legendary tunnel was carved in the late 1920s (around 1927) by the French Foreign Legion, requiring monumental effort using primitive tools against the mountain's solid rock. Stretching approximately 60 meters long, it is known locally as a symbol of human perseverance against harsh natural elements. The tunnel is more than just a road passage; it is a gateway that evokes a sense of awe as travelers drive through the dark rock into the blinding light of the canyon. A stop at the tunnel's exit offers a stunning view of the Ziz River, allowing visitors to reflect on the history of caravans and armies that once traversed this strategic pass connecting northern Morocco to the Sahara. It is an essential stop for history buffs and travelers seeking the raw, untamed spirit of the Atlas.
